Versions of MSA
[What's New in Version 3]
Provided the new version differs
in the second digit (e.g., 3.5 versus 3.4), it should not be necessary to uninstall the
prior version before installing the new version of MSA. Version 3.5.0, for
example, will install in the folder "Market System Analyzer 3.5" by default,
whereas version 3.4.1 should be installed in the folder "Market System Analyzer
3.4." Also, provided the installation is on the
same computer as the prior version 3 installation, no new activation code should
be required. The new version should install already activated. MSA version 2 and
MSA version 1 do not need to be uninstalled prior to installing version 3.
Please note: uninstalling an older version will not affect any MSA files (.msa
or .msaport) you may have created or saved.
Version 3.5.0 (December
MSA Version 3.5.0 includes a new Monte
Carlo algorithm that uses parallel processing to take full advantage of
multi-core processors. This not only dramatically speeds up stand-alone Monte
Carlo analyses in MSA but improves processing times for position sizing
optimization and the Parameter Studies feature when the Monte Carlo option is
selected for these functions.
Also new to version 3.5 is the ability to
read trade data from RINA xml files, which can be generated by trading software
such as TradeStation and MultiCharts. The File Open command can now be used in
MSA to directly open one or more text files of trade data, including xml files,
and create a new MSA document in the process. Multiple files of trade data, such
as multiple xml files, can be merged into one MSA document, or a separate
document can be created for each file of trade data, with an optional portfolio
file created as well.
In addition, this release includes the following
- Separate fields have been added for entry and
exit trade times. Previously, it
was necessary to represent trade entry and exit dates and times in combined
date/time fields. MultiCharts produces output files that include separate
fields for date and time. MSA now supports this.
- Also in support of MultiCharts, the words "EnterLong"
and "EnterShort" are now accepted as descriptions of trade direction in the
Long/Short column of a file of trade data.
- In the Return Tables section of the Performance
Report, the limit on the number of displayed rows has been removed. All rows
of results for yearly, monthly, weekly, and daily returns are now shown.
- [bug fix] When the main plot was set to display
Monte Carlo results and a setting was changed that affected those results,
the display went blank for 10 second before reverting to the regular equity
plot and displaying a message stating that the Monte Carlo analysis needed
to be rerun. This behavior has been changed so that if the current plotting
is for Monte Carlo results, any change that affects those results causes the
Monte Carlo analysis to be redone automatically and the Monte Carlo plotting
to be updated without user intervention.
- [bug fix] Clicking the "font" button on the Chart
Format window caused the program to crash.
- [bug fix] Formatting errors were
present on the portfolio optimization results window related to the display
of the names and paths for the market-system files comprising the portfolio.
The same errors were corrected on the results window for the Monte Carlo
analysis for portfolios.
- [bug fix] When entering trades
manually through the editor (Edit/Add Trades window), if the profit/loss and
risk fields were left empty, the corresponding values were set to zero,
rather than as undefined. The zero values could subsequently affect the
results if the selection on Analysis Setup was to use profit/loss and risk
values, rather than prices.
- [bug fix] Incorrect column labels on the trade
export results have been corrected.
- [bug fix] The missing cursor for dragging the
vertical divider between the Performance Summary window and the main chart
window has been restored.
Version 3.4.1 (December
MSA Version 3.4.1 contains the following
bug fixes and changes:
- Trade entry and exit prices have been
added to the Equity Table for both market systems and portfolios.
- [bug fix] The "ideal equity curve"
line on the equity chart was incorrectly plotted as logarithmic under linear
scaling and vice-versa for the constant value position sizing method. This has been corrected.
- [bug fix] The formatting in the
Equity Table was incorrect for some values less than 1, including risk
values, although the internal representation and calculations were correct.
The formatting has been
- [bug fix] Addition and withdrawal
"trades" were duplicated when the file was re-opened after saving in version
3.4.0. This error only affected version 3.4.0 and has been corrected.
- [bug fix] The delta fraction for
fixed ratio position sizing was not read when using the "Set All" command
for portfolio position sizing, resulting in the default value of 1.0 being
used. This has been corrected.
- [bug fix] A fixed fraction of 100%
was shown as "10" in the summary panel and in the Equity Table. This has
Version 3.4.0 (June
MSA Version 3.4.0 adds a new
type of Monte Carlo analysis designed to detect the failure of a trading
strategy or portfolio of strategies. This new Monte Carlo analysis extrapolates
the equity curve forward by a user-specified number of trades to produce a
prediction envelope. By comparing the actual equity curve to the prediction
envelope, abnormal trading can be detected. This new feature is discussed in the
user's guide and help files in the chapter on Monte Carlo analysis, as well as
recent newsletter article.
In addition, the following
bug fixes and changes were made:
- [bug fix] Risk metrics, including
expectancy and R-values, were set to zero in version 3.3.0 and 3.3.1 even
when trade risks were defined. This has been corrected.
- [bug fix] Trade files generated from
a TradeStation performance report, as well as any file of trade data
containing a blank line, caused MSA 3.3.0 and 3.3.1 to hang. This has been
- [bug fix] Some settings affecting the
Monte Carlo analysis results, including re-optimizing the position sizing,
did not invalidate the Monte Carlo results, causing a mismatch between the
settings and the Monte Carlo results. This has been corrected.
Version 3.3.1 (May 28, 2013)
This release corrected errors in version 3.3.0 that affected how the trade
files were read for some non-US locales. The errors resulted in missing decimal
digits for price values for some locales and zero values for fields such as the
profit/loss in some cases. The only other change in this version relative to
version 3.3.0 was that the functionality of the buttons on the Getting Started
screen, which didn't work in the prior release, was corrected. Version 3.3.0
should be uninstalled prior to installing this version.
Version 3.3.0 (May 24, 2013)
In MSA version 3.3.0,
the Monte Carlo analysis was updated so that the
equity plot displays probability bands
resulting from the MC analysis. A new "Current Sequence" drop-down menu in the menu
bar changes to "Monte Carlo", and four equity curves are displayed,
representing the current sequence of
trades, the upper and lower confidence bands for the Monte Carlo analysis, and
the equity curve at 50% confidence.
In addition, the following
bug fixes and changes were made:
- [bug fix] The portfolio Monte Carlo
analysis calculated the optional results incorrectly by only including the
last market system in the portfolio. This has been corrected.
- [bug fix] The "Skip first..." edit
box on the Trades File Format window allowed the user to enter a value but
didn't respond to it. The user can now either use the spin controls or
directly type in a value for the number of lines to skip.
- To avoid long processing delays, only
the first 100 lines are now shown in the Trades File Format window.
- [bug fix] The last character of the
symbol for the last trade in a file of trades formatted for "WriteTrades"
was not read on import or via Data Source. This has been corrected.
- [bug fix] The Trade Type field was
not read correctly when text codes were used. This has been corrected.
- [bug fix] The currency conversion
factor was incorrectly multiplied by the entry, exit, and stop prices and by
ATR before storing these values, resulting in incorrect values in the stored
file. This has been corrected.
- [bug fix] The correlation coefficient
was calculated using the wrong range of trades in some cases when market
systems had been saved with a modified date range. This has been corrected.
- The time-out interval for searching
for a file of trades has been reduced from one minute to 30 seconds.
- [bug fix] If a portfolio was defined
with a market system file that contained no trades, the program would crash.
This has been corrected.
- [bug fix] In fixed ratio position
sizing, the first level of increase was calculated based on an initial size
of 1, regardless of the specified initial size. This has been corrected.
Version 3.2.1 (May 3, 2010)
MSA version 3.2.1 corrects the following
- When the trade list is manually edited via Edit/Add Trades (Trades menu), the account and trades locales
were reset to the computer's default setting.
- In portfolio files, when the trade risk data were defined in terms of prices, rather than amounts, a point
value of 1.0 was used in calculating the risk values, rather than the
correct point value entered under Setup. This could result in incorrect
values in the portfolio performance report for average risk, average % risk,
ave R-multiples (wins), ave R-multiples (losses), overall ave R-multiple
(expectancy), and standard deviation of R-multiples. This only affected
these metrics for the portfolio when the market-system risk data were
defined in terms of prices.
Version 3.2.0 (October 16, 2009)
MSA version 3.2 provides the following
- Updated user interface with the
- Tabs are now used to display the open documents.
- Tabs can be grouped into horizontal or vertical panes.
- The program stores the open windows when exiting and opens the documents the next time the program is started.
- Different styles/color schemes can be selected for the user interface to match popular Windows
programs, such as Office 2007, Windows XP, etc.
- The tool bars can be customized.
- The right-click (floating) menus can be customized.
- Ability to plot the equity curve by
day, week, month, or year. The equity change over the selected period is
used in plotting, with one equity point per period.
- The .msp extension for portfolios has
been changed to .msaport to avoid conflicts with Windows installation files.
For backwards compatibility, MSA 3.2 can open and read either .msp or .msaport
- The option to add periodic
withdrawals to the equity curve simulation has been added. Withdrawals can
be specified on a weekly, monthly, quarterly, or annual basis.
- Two new position sizing methods have
been added: percent volatility position sizing bases the position size on
the average true range, and constant value position sizing sets the position
size so that the position has a specified value (e.g., $5000 per trade).
- A second delta has been added to the
fixed ratio position sizing method for decreasing the position size, so that
the rate of increase and the rate of decrease can be specified
- A file properties window is available
from the File menu, which lists file details of the document currently
- The following types of moving
averages can now be specified for computing the moving average for equity
curve crossovers: simple, exponential, weighted, TRIX (triple
- The following new performance metrics
have been added: pessimistic return ratio, average R-multiples (wins),
average R-multiples (losses), average R-multiple (overall), R-multiple
standard deviation, average risk, average margin, max margin, date of max
margin, average leverage, risk of ruin.
- The trade editor has been redesigned
to improve usability. Multiple trades can be deleted together using shift
- New data input fields are available
including market symbol, trade type (regular, cost/fee, add/withdraw),
currency conversion factor, and average true range.
- Multiples .msa and .msaport/.msp
files can be opened together using the File - Open command.
- The equity table can now be sorted by
any column by clicking on the column heading. The table has been expanded to
include the new data fields.
- The Edit/Add Trades dialog and Trades
File Format dialog windows are now resizable.
- The full-screen cursor box, displayed
when clicking the mouse over the chart window, now displays the equity value
at the cursor location ("Equity"). The account equity at the selected trade
is displayed under "Account" and the date of the trade under "Exit Date".
Bug fixes in version 3.2.0:
- Weekly results in the Return Tables tab of the performance report has been corrected so that each listed week
starts on Sunday. The date for the listed week is the date for the Sunday on
which the week starts.
- An error has been corrected that occurred when writing reports to a text file in which the report contained
no date information.
- An error related to the date/calendar control has been corrected in which the program selected the incorrect trade
based on the selected date when multiple trades had the same date with different times.
- The portfolio optimization now returns zero, rather than a negative number, for the position sizing
parameter when the associated market system does not contribute to the portfolio equity.
- An error related to rounding errors resulting in negative position sizes has been corrected. This occurred when
a series of overlapping trades resulted in zero available equity.
- When the portfolio performance report was displayed and the portfolio was closed, the report dialog window was not
closed. This has been corrected.
- Updating of the Equity Table window has been improved to reduce unnecessary redraws.
- The full-screen cursor sometimes appeared when the chart was initially opened. This has been corrected.
- Opening a portfolio file sometimes crashed MSA in cases where the trades file in the .msa file had been
changed. This has been corrected.
- Previously, if all trades were deleted under Edit/Add Trades, the program crashed when clicking OK. This has been corrected.
- If all trades were deleted via "Clear All", the right-hand summary pane did not update. It now resets the
performance numbers to zeros.
- When an empty portfolio was created with two empty market-system files, calling the Trade Size command for the
portfolio caused the program to crash. This has been corrected.
- A problem with an internal number formatting function has been corrected that caused improper rounding in some cases.
- When selecting "save as" from the File menu, the program now prompts for a new trades file in addition to a
new .msa file.
- When a market-system was randomized then saved, the program opened with the "restore" function dimmed. This has
- When MSA cannot find the trades file specified in the .msa file, the search function now times out after 60
seconds, rather than continuing to look for the file, which previously caused the program to wait for extended periods of time.
- On the Trade Size and Portfolio Trade Size windows, clicking the calculate button is now the same as hitting the
Enter key, so hitting the Enter key no longer closes the window.
- Printing of reports has been corrected so that long lines are no longer truncated. The print size is
reduced so that the report fits the paper.
- A problem with an internal number formatting function has been corrected that caused an error when the number
being formatted was too large.
Known issues in version 3.2.0:
- The cursor disappears when selecting the resizing bar between panes on the main window.
- Window tab settings (e.g., horizontal or vertical pane settings) are not stored when the program exits.
implements three minor bug fixes over version 3.1 and modifies the
trial/registration module to reset the trial for those who've tried a prior
version of MSA 3.
- If MSA has not yet been activated, the trial will
automatically reset to 30 days when a newer version of MSA 3 is installed,
provided the old version is uninstalled first.
- [bug fix] On the performance report (Settings tab)
for market-system documents, the trades file path did not display the
backslash (\) character.
- [bug fix] On the performance report (Return Tables
tab) for both market-system and portfolio documents, the table headings ran
together when there was no data to display (i.e., when no date data was
- [bug fix] In some cases, the right-hand panel did
not display the font size properly.
represents the official release version of Market System Analyzer (MSA) 3.
- Portfolio optimization has
been implemented. Each market system may use a different position sizing
method if desired, and stocks and futures can be freely mixed in the same
- The optimization command for market systems now
opens a window that stays on the screen while the optimization is ongoing to
provide additional feedback and intermediate results. It's now possible to
work in other windows in MSA while the optimization is ongoing.
- Correlation analysis has been implemented for
portfolios. A correlation table has been added to the performance report.
The correlation analysis is automatically performed whenever the portfolio
document is recalculated.
- An option has been added to automatically reload
the chart at specified intervals, such as every 5 seconds or every 2
minutes. This is intended to facilitate the use of MSA for day trading where
the trades file is automatically updated after each trade.
- Dependency analysis and significance testing are
now calculated automatically whenever the document is recalculated. Tabs for
the corresponding results have been added to the performance report. The
user settings for dependency analysis and significance testing have been
moved to the Setup command window.
- The user's guide and help files have been updated
through this version.
- The performance of the tabbed performance reports
(market system, portfolio) has been improved to reduce screen flicker and
correct scrolling errors.
- The floating (right-click) menu has been expanded
to include most functions from the Analysis and Portfolio menus.
- The toolbar has been expanded to include icons for
the most commonly used Analysis and Portfolio menu functions.
- On the Portfolio Position Sizing dialog window,
the Set All window has been redesigned to improve functionality.
- Color schemes have been added to the Format Chart
window, Lines and Colors tab.
- Copy-to-clipboard functionality has been added.
The Ctrl+C keyboard combination can be used in the main window, the
right-hand pane, and in most results windows. Copying the main chart copies
a bitmap of the chart to the clipboard. Copying elsewhere copies the text
from the window to the clipboard.
- All the results windows (performance results,
Monte Carlo results, optimization results, equity table for market-system
and portfolio documents) can be saved to the following formats:
tab-delimited text (.txt), comma-delimited text (.csv), unformatted Word
(.doc), and html (.htm).
- On the Trades File Format window (used with Data
Source or importing trades), the preset format for TradeStation Trades List
has been updated for TS 8.3.
- [bug fix] Font changes made to the chart also
applied to the cursor box displayed when clicking the mouse on the chart,
sometimes resulting in text that was too large for the cursor box. This has
been corrected so that the font for the cursor box does not change.
- [bug fix] Performing a Clear All command then
saving the market-system document resulted in an error when trying to open
the empty trades file then selecting another trades file. MSA will not
properly open an empty trades file.
- The order of the periodic
performance results in the Return Tables part of the performance reports has
been reversed so that the most recent results are on top.
- Two new options have been
added to the Trade Size command for the portfolio. When entering the data
for each market system, a box can be checked to exclude the market system if
there is no new entry signal. If there is an open trade, a second box can be
checked, and the position size for the open trade can be entered.
- Feedback for plot-by-date errors has been
improved. If the program can't plot by date due to a missing or incorrect
date, the trade where the problem occurs is noted in a error box displayed
to the user.
- The options for drawing tick marks and new equity
highs has been improved to allow marks at equity highs by themselves without
requiring tick marks on all trades.
- Portfolio files now search for market-system files
(.msa) in the folder where the portfolio (.msp) file is located if the
market-system files can't be found in their specified locations. This makes
it easier to copy portfolio files or send them to someone else. Provided the
portfolio, market-system, and trades (.csv) files are all in the same
directory, MSA will be able to find them. MSA will also search in standard
locations, such as the Documents folder, for .msa and trades files that are
not found in their specified locations.
- The wording on the Setup screen for the risk-free
interest rate used in calculating the Sharpe ratio has been changed to
indicate that a monthly interest rate should be entered. Because the Sharpe
ratio is calculated from monthly rates of return, the risk-free interest
rate should be the interest rate per month, not an annual rate.
- [bug fix] Whenever the trades file was written, it
was saved with only two decimal digits of precision. The trades file is now
saved with a total of seven digits of precision.
- [bug fix] Exporting the trades file has been
corrected to include a total of seven digits of precision, up from two
- [bug fix] When all trades are short, the
performance summary misaligned the columns so that they overlapped. This has
- [bug fix] Extra space has been removed from the
text file generated when exporting the trades file to make the format
compatible with Excel.
- [bug fix] Adding trades created with the
statistical trade generator ("Create Trades from Statistics") to trades
plotted by date gave an error. This has been corrected.
Versions 3.0.0 through 220.127.116.11
In addition to the changes discussed above, version 3
(through 18.104.22.168) includes the following:
- Performance results have been expanded to include:
Results for long and short trades tabulated separately
Period returns for each month and year and for the most recent 100 weeks and days
Average yearly, monthly, weekly, and daily returns
True Sharpe ratio based on monthly returns and
using a user-adjustable value for the risk-free rate of return
Average and standard deviation of the annual,
monthly, weekly, and daily results, including net profit, return,
drawdown, number of trades, percentage wins, and profit factor
- Right-clicking or double-clicking in the results
summary (right-hand) pane brings up the full performance report.
- Performance reports can be printed from the
performance results window or saved to a file in the following formats:
.txt, .doc, .csv, .htm, .html.
- The graphics in the main chart have been improved:
- New highs in equity can be optionally marked on the chart.
- An empty chart can be formatted to use as a template.
- Clicking on the main chart displays a full-screen cursor with an information box to display chart details.
- Drawing of the zoom selection box has been improved to reduce screen flicker.
- When viewing a portfolio equity curve, the equity curve for any one of the market-systems comprising the portfolio
can be optionally plotted.
- The floating menu, accessible by right-clicking in
the main window, now includes the most commonly used menu items from the
Analysis, Portfolio, and View menus.
- Initially, the starting account size is set to an
estimate of the minimum equity required to trade the strategy. The estimate
is calculated by adding the one-contract/share drawdown to the
one-contract/share margin requirement and multiplying by the largest
position size in the input data.
- The results summary in the right-hand pane now
- Negative prices are now valid, which allows
back-adjusted prices series data to be used even in cases where the
back-adjusting results in negative values.
- Version 3 is fully Vista compatible.
- A new registration/licensing system prevents
errors occasionally encountered under Windows 2000 and Windows XP Pro.
- The following bugs have been corrected:
- MSA crashed when the number of non-empty days of performance results was exactly equal to the display limit.
- Trades files were not read correctly when using non-US locales.
- Trade risks were not saved in the trades file after defining them using the
Create Trade Risks command.
- Results file exported to .txt format did not open correctly in NotePad.
- In the position sizing window for portfolios, the market system column was blank if a label had not been defined for
the market system. It now uses the file name if a label has not been chosen.
- Edit/Add dialog did not save data correctly when using non-US locales.
- Trying to import a file that was already open on the user's desktop generated an error.
- Hard-coded "$" symbols have been replaced with the symbol based on the selected locale setting.
- The risk-free interest rate has been added for the portfolio Sharpe ratio.
- The date selector on the menu bar can now be changed manually by typing into the date field.
- The number format in the Edit/Add Trades window has been increased to 7 digits in total.
- Negative position sizes are no longer allowed.
What's New in
The following information is intended primarily for those who are
migrating from MSA Version 2. Version 3 was designed to encapsulate the
functionality of version 2 while adding portfolio analysis. This was done by
(1) adding a second file type for portfolios, and (2) allowing multiple
windows/files to be open at the same time. In addition to files of type .msa,
version 3 uses a new file type to represent portfolios. Starting in version
3.2, portfolios use the file type .msaport. In versions 3 prior to 3.2,
portfolios had the file extension .msp. Current versions of MSA can open
either .msp or .msaport files.
The vast majority of features and operations pertaining to market systems
remains the same in version 3 as in version 2. Working with .msa files and
market systems in general is very similar in both versions of the program.
In addition, version 2 files can be opened directly in version 3.
The main difference in version 3 is that once several market-system (.msa)
files have been created, a portfolio can be defined. This is done by opening
a new portfolio (.msaport) file, then selecting two or more market-system (.msa)
files from the Setup window. Once the market-system files have been
selected, the trade histories are combined by MSA to show the resulting
portfolio equity curve.
While most features in version 3 pertaining to market systems are the same
as in version 2, there are a few differences. In version 3, market systems
can have entry and exit dates for each trade. Exit dates are required for
each trade if you want to view results that relate to date/time, such as the
return each month or year. Entry dates are used primarily to track margin
usage when multiple trades occur together. When migrating a version 2 file
to version 3, dates can be added in an approximate manner in the Edit/Add
Trades window (Trades menu) using the Set Date Range.. button. This enables
you to set the dates for each trade based on the starting date, ending date,
and average trade length for all trades in the history. To add the exact
entry and exit dates for each trade, either re-import the trade data from a
file that includes dates or use the Data Source command (Trades menu)
to set the trades file to a text file that contains the trade data with
When exit dates are available for all trades, the equity curve in the main
chart window can be plotted either by trade or by date. To change to
plotting versus date, version 3 has a Plot by Day/Week/Month/Year/Trade
pull-down menu selector in the menu bar at the top of the window. You can
also choose to limit the trade range by date in version 3 using the date
selectors in the menu bar. After selecting the starting and ending dates,
click the Recalculate button to recalculate the equity curve for the new
range of trades.
Version 3 also allows multiple windows and files to be opened at once. For
example, you might have several market-system files open as well as a
portfolio file. Each file will be shown in its own tab. The menus available
in the main window frame depend on the type of tab/file selected. When a
portfolio file is open and selected, the menus in the main window reflect
the options available for portfolios, including a Portfolio menu. When a
market-system file is open and selected, the menus reflect the available
options for market systems, including the Trades and Analysis menus. Trades
are only entered, imported, and edited in market systems, not portfolios. To
enter or import trades, a market-system window must be selected. By default,
the files opened when the program was last closed are opened when the
program is opened from the Windows Programs menu or desktop.
When opening a version 2 file in version 3, the equity curve crossover
and dependency rules may need adjusting. In version 2, several of the
equity curve crossover and dependency rules adjusted the position sizing
parameter value by a specified percentage based on the rule logic. For
example, the fixed fraction might have been increased 20% on an equity curve
crossover. In version 3, the rules change the position size directly, rather
than changing the position sizing parameter value. Instead of increasing the
fixed fraction by 20%, the same rule in version 3 will increase the position
size by 20%. In some case, this will have the same effect as the old rule.
However, in some cases, the effect will be in the opposite direction. For
example, increasing the fixed equity amount is the same as decreasing the
position size. When working with a version 2 MSA file in version 3 for the
first time, each crossover and dependency rule should be reviewed and
adjusted if necessary to make sure it works as desired.
Also keep in mind that while MSA version 3 can read version 2 files, the
reverse is not true. MSA version 2 cannot read version 3 files, so if you
want to be able to continue to use a version 2 file in MSA 2, it's important
to "save-as" your version 2 file to a different name in version 3. Once a
version 2 file is saved in version 3, it becomes a version 3 file and will
not be readable by version 2.
For non-US users, starting with version 3.0.3, you can change the
number/currency format (locale) from the Setup
command to match the currency that your trading account is
denominated in. For example, if the locale is set to Germany, the currency
symbol will be the Euro symbol, and the thousands separator will be the "."
rather than the "," used in the US. It's not necessary to change the Windows
locale, as in previous versions. You can select an account locale for each
market-system file and for each portfolio file. You can also select the
number/currency format for the trades file. For example, if using the
WriteTrades function for TradeStation, the number format will be "US". If
your account is in Euros, you could select Euros in Setup for your account
and "$" for the trades file format. The format for the trades file is set on
the Trades File Format window when using the Data Source command or
when importing a trades file. Please note: MSA does not include a currency
converter. If you have market systems with different account locales and you
combine these into a portfolio, MSA will not convert the currency values
from the market-system locale to the portfolio locale. However, starting in
version 3.2, there is an input data field for currency conversion. The value
in this field is multiplied by the entry, exit, and stop prices, as well as
by the average true range (ATR) value.
An important difference in version 3 is how trade data are stored. In
version 2, the trade data were stored in the .msa file. In version 3, the
trade data (entry price, exit price, entry date, exit date, position size,
etc.) are stored in a separate text file that is specified using the new
Data Source command of the Trades menu. This new feature is designed to
make it easier to update and work with trade data files. The Data Source
command allows you to specify the file where trade data are stored and
identify the columns of data that MSA should read. If you edit trades within
MSA, the trades file is updated accordingly. Likewise, if you change the
trades file outside of MSA, the market-system file will change the next time
it's opened or if you select Reload From File from the Trades menu. By
storing the trades in a separate trades file, several MSA files can
reference the same file of trades. If the file is changed, all MSA files
that use that trades file will automatically reflect that change. Also, any
portfolio file based on the MSA file will be updated as well.
If you import trades into MSA from a text file using the
Import command, the next time you save
the MSA file, the program will prompt you for a file name for storing the
trade data. This will be the "trades file" for your MSA file. Any changes
made to the trades while in MSA will be stored in the trades file. If you
want to use the text file from which you imported the trades as your trades
file, you can save a few steps by using the Data Source command to
define your trades rather than importing them.
