MT4 Backtesting Issue

It is weird !

My MT4 platform was updated to version build 509 last week. Then once the updated was completed, i closed it and restart the platform. After that, i did my EA backtesting, the result is good. Now, i open my MT4 platform to backest again the EA, but the result is completely changed, it is losing now.

So what's happen actually ? Something wrong with the historical data? Anyone has encountered this before? Or someone here could advice me what should i do?

Thanks.

What was the Spread last week when you ran the Strategy Tester ? what was the Spread when you tested the second time ?
20 pips a day isn't too much to ask . . .

I am not sure actually because i ran it as normal last week. I did the test on build 451 before the update, the result was good as well. I have noticed now there is a adjustable spread cell at the tester in build 509, which i could test it with fixed spread. Now if i try to backtest with low fix spread, i can get good result. May i know if spread is different for demo and live ?

Fyi, i am not using tick data to test the EA, and the broker is demo GFT.

spread reset
You mean platform will reset the spread to zero after the update?
I have searched the website, seem many traders lose money once he/she get the new build updated. So in this case, restart the PC will solve the issue, which i did off my PC on weekend?
