Topic: Big difference in backtest on FSB vs. MT4 using identical price data
I see this subject has been discussed a lot but I don't see any clear answer to the simple question:
Which backtest platform is more rigorous, accurate and reliable - FSB or MT4?
I ran backtests using the identical 16 months of Alpari historical price data and start and end dates on a strategy developed on FSB and saved as an MT4 EA.
I would expect very similar results but this was not the case at all:
The strategy had no losing trades on FSB (299 total trades) but there were 5 losing trades on MT4 and some different trades were taken. (the strategy requires an extremely high win/loss ratio - taking small profits and big losses)
On FSB with 'pessimistic' setting I got virtually identical results with the Alparia data vs. the FSB demo data.
The Alpari MT4 backtest used the 'every tick' model - and showed 90% modelling quality in the report (with 278 trades).
Is the MT4 backtest more strict and/or accurate than the FSB backtest and therefore the more rigorous test result to evaluate a strategy backtest?
I started a live 'forward' test and the 3rd trade was a loser.
Any guidance would be much appreciated.
