MT4 Backtest Help!!!

 

Hi everyone,

I need some advice regarding backtesting in MT4. I have developed a mechanical EA that references the previous bar [1], the current bar [0] and the current bid or ask price. The system is based on the daily chart, mainly gbpusd and gbpjpy. When I backtest my EA misses a lot of setups that meet my criteria, for no apparent reason. I'm also trying to get good modelling quality for the past year but can't get anywhere near the 90% mark. I have heard of an Alpari build which is better, is this what I need? Could that be the reason why my backtest misses some setups? Any assistance would be greatly appreciated.

thanks!
