backtesting - differrent results for the same period for two differrent brokers

 

I am back testing a strategy on IBFX and FXCM platforms.. for the same period and the for the same pair.. the results between 2 are very differrent.

Only differrence is on FXCM lot size is Mini and IBFX lot size is Micro.. I am not comparing the $ profit numbers.. I am comparing the % factor.. and the results are very differrent. I also tried with MBT MT4. It is also differrent .. though little close to IBFX.

Can this happen ? If yes, what can be the reason ? comments ?

 
gordon:

For consistent results in the Tester u need identical History Data and identical Market Properties (in the Tester -> press 'Symbol properties'...). If there are differences in either, then results will differ.
