Hello Simon,
Glad to hear from you. You should be getting the same results with FSB Pro/EA Studio and MT Backtester. Before I give you some reasons, what you are missing, can you please post the following pictures:
1. The strategy in EA Studio – with the entry/exit rules, everything, simply the Editor of it
2. The MetaTrader where you do the backtest
3. The statistics of your Data – go to EA Studio Data – Data statistics
Kind regards,
