Report Merger is a useful tool for traders planning to run multiple EAs on the same account. Report Merger makes it much easier to test multiple strategies running concurrently even with money management enabled. You can easily check the expected risk and gain and adjust money management parameters to get an optimal portfolio.
Adjusting parameters and (re-)merging backtests in Report Merger is much faster than re-running strategies in MetaTrader. A typical merge takes only a few seconds on a usual computer while running a backtest could take hours on a decent hardware.
Report Merger is a desktop application capable of processing MetaTrader 4 backtest reports and runs under Microsoft Windows.
Report Merger recalculates the very same statistics as MetaTrader does plus a lot more:
For every statistics Report Merger calculates values in pips too (only where valid).
The generated report contains all the above statistics plus the settings for each expert used in the merge and the list of all executed trades ordered by close time.
You can have a look at a sample merged report here.
Currently Report merger doesn't calculate floating drawdown which is due to the lack of price feed. The other limitation is that trade times are always broker dependent, they aren't converted to a common time zone so trade order might not correspond to actual execution order. However this doesn't affect graph/statistics significantly.
First of all, run all the backtests You want to merge in MetaTrader terminal as usual. Aim for the best possible modelling quality (99% or at least 90%) with no chart errors. Keep in mind that You should run all the backtests using the same deposit currency.
When all the statements are ready simply import them using the “Add…” button and browse for the statements. Multiple statements can be added at once.
After the backtests are imported You can finetune their settings per backtest by right clicking in the list:
