Addendum to the installation instructions of xxTrader.exe:
8) Ensure that there is only one copy of ABtool.dll and xxTrader.exe is one your
machine (on all drives, incl. network drives). Otherwise a DLL load error will happen.
Here again:
- The correct location of ABtool.dll is the "Plugins" subdirectory under the
AmiBroker base directory.
- The correct location of xxTrader.exe is the "ABtool" subdirectory under the
AmiBroker base directory.
- The correct location of xxRankedSys.afl is the "ABtool/xxRankedSys" subdirectory
under the AmiBroker base directory.
- The correct location of xxScoring.afl is the "ABtool/xxRankedSys" subdirectory
under the AmiBroker base directory.

Subject: [abtool] ANN: xxTrader v1.00 released
> xxTrader is an external Scoring&Ranking Backtester for AmiBroker.
> It requires the ABtool.dll plugin v0.9.21 or higher. The file can be
> downloaded from the ABtool and xxTrader home page at:
> http://groups.yahoo.com/group/abtool
>
>
> Documentation of xxTrader's Scoring&Ranking Backtester Part:
>
> Installation and configuration steps:
>
> 1) xxTrader.exe requires AmiBroker v4.x or higher and the ABtool.dll plugin
> version 0.9.21 or higher. As usual the plugin must reside in the "Plugins"
> directory under the AmiBroker base directory.
>
> 2) You must add the full path to the "Plugins" directory into your PATH environment
> variable. Otherwise xxTrader.exe cannot find/load the ABtool.dll. For example
> the following string must be appended to your PATH variable:
> ;C:\Program Files\AmiBroker\Plugins
> Consult your operating system manual on how to do this. Mostly it is done
> via "My Computer/Advanced/Environment variables". Select PATH and append your string.
>
> 3) xxTrader.exe must be put into the ABtool directory.
> You can add it to the Tools menu of AmiBroker. But then leave the working
> directory empty, and also don't specify any parameters.
> AND: before starting xxTrader AmiBroker+ABtool must already be running.
> So, it is wise to put xxTrader into the Tools menu of AB and start it only
> from there.
>
> 4) Put the xxRankedSys.afl file into ABtool/Systems/xxRankedSys directory.
> Create this directory if it isn't already existing.
>
> 5) Put the xxScoring.afl file into ABtool/Systems/xxRankedSys directory.
> This is the only source you should edit. Place your scoring algorithm
> in this file. There is already a default algorithm supplied.
>
> 6) If you would like to start a batch file before the backtesting begins then
> place the file PreRun.cmd into the ABtool/Systems/xxRankedSys directory
> and edit its content for your needs. The default PreRun.cmd does nothing.
>
> 7) If you would like to start a batch file after the backtesting ended then
> place the file PostRun.cmd into the ABtool/Systems/xxRankedSys directory
> and edit its content for your needs. The default PostRun.cmd file starts
> Excel and opens the resulting CSV files (tested only under Win2000).
>
>
> Operating instructions:
>
> 1) Start AmiBroker
>
> 2) Start xxTrader
>
> 3) If there are any xxTrader related files open in any program (for example in Excel)
> then close them (otherwise you will be prompted to close them before writing the results).
>
> 4) From the Tools menu of xxTrader invoke xxRankedSys and fill the required fields
> and start the process by pressing the OK button.
>
> 5) The results will be put into the ABtool/Systems/xxRankedSys directory. The files are
> Portfolio*.csv and
> Summary.csv
> Summary.csv is a collection of all results, whereas the Portfolio*.csv file will be
> overwritten after each run with the same initial capital.
>
>
> How it works:
> 1) xxTrader asks user for parameters and writes them to the file xxParameters.afl
> 2) It invokes AA which then executes the system script
> 3) The system script calls user functions in xxScoring.afl
> 4) The results are put into CSV files
> 5) Via PostRun.cmd, Excel or any other application can be started to analyze the results files
> 6) The system settings are preserved for the next run.
>
>
> Your part:
> The ranking and producing of the results is done by xxTrader. Your part is to supply
> the scoring routine. It must be done in ABtool/Systems/xxRankedSys/xxScoring.afl.
> Edit this file to suit your needs. Do not edit the xxRankedSys.afl file.
> The scoring should be a number between 0 and 100, but this up to you; you can
> also use a different range. Just imagine where it would be placed if sorted.
> In xxTrader the interpretation of the Score is as follows:
> - The higher the score the better it is for Short trades
> - The lower the score the better for Long trades
> See also:
> - ABtool/Systems/xxRankedSys/xxScoring.afl
> - ABtool/Systems/xxRankedSys/xxParameters.afl (will be generated by xxTrader)
> - ABtool/Systems/xxRankedSys/PostRun.cmd

> Results in Portfolio*.csv:
> "RelPerf" (column AC): This the chronological performance of the system.
> "MaxDrawDown" (column AR): Max Draw Down
> "CurCapital" (column AA): The current value of the portfolio
> (there are about 50 other columns in this table)
>
>
> Results in Summary.csv:
> Here a summary of each backtesting run is recorded (appended).
