Backtest_many will test all system listed in a system file on all the values listed in the market file.
The <system file> contains one line per defined system, where each system is defined by its full system name or by an alias. An alias is defined in the configuration file with entries of the form Aliases::Global::<alias_name> <full_system_name>.
The full system name consists of a set of properties, such as trade filters, close strategy, etc., together with their parameters, separated by vertical bars ("|"). Multiple properties of the same type can be defined, e.g., there could be a set of close strategies. For example, System:ADX 30 | TradeFilters:Trend 2 5 | MoneyManagement:Normal defines a system based on the "ADX" system, using a trend following trade filter "Trend", and the "Normal" money management.
The following abbreviations are supported: Systems = SY CloseStrategy = CS TradeFilters = TF MoneyManagement = MM OrderFactory = OF Signals = S Indicators = I Generic = G
Another example of a full system name is SY:TFS|CS:SY:TFS|CS:Stop:Fixed 4|MM:VAR.
Determines the time interval to consider for analysis. In detail:
The start and end dates considered for analysis. The date needs to be in the format configured in ~/.gt/options and must match the timeframe selected.
The number of periods to use in the analysis.
Consider all available periods.
The periods considered are relative to the selected time frame (i.e., if timeframe is "day", these indicate a date; if timeframe is "week", these indicate a week; etc.). In GT format, use "YYYY-MM-DD" or "YYYY-MM-DD hh:mm:ss" for days (the latter giving intraday data), "YYYY-WW" for weeks, "YYYY/MM" for months, and "YYYY" for years.
The interval of periods examined is determined as follows:
The first period determined following this procedure is chosen. If additional options are given, these are ignored (e.g., if --start, --end, --full are given, --full is ignored).
The timeframe can be any of the available modules in GT/DateTime.
Determines the number of periods (back from the last period) that are loaded for a given market from the data base. Care should be taken to ensure that these are consistent with the performed analysis. If not enough data is loaded to satisfy dependencies, for example, correct results cannot be obtained. This option is effective only for certain data base modules and ignored otherwise.
Calculate commissions and annual account charge, if applicable, using Finance::GeniusTrader::Brokers::<broker_name> as broker.
If you want to start two (or more) backtests in parallel (useful for machines with several CPUs for example).
Stores the backtest results in the "backtests" directory (refer to your options file for the location of this directory) using the set name SETNAME. Use the --set option of analyze_backtest.pl to differentiate between the different backtest results in your directory.
A configuration option (typically given in the options file) in the form of a key=value pair. For example, --option=DB::Text::format=0 sets the format used to parse markets via the DB::Text module to 0.
