drastic differences!
You call that different?!!!
How about those results from build 200, the first using downloaded mt data, and the other uses alpari data. Both terminals were offline so historical data was not tampered with. Both use the same EA with the same parameters and 90% modeling quality data. Also it's same timeframe, same machine and same user (me!!)
Is there something seriously wrong with the tester in this version?
In any case, attached is the EA in case you wanted to check to see if it will have similar results with you!
This is driving me

feedback appreciated!If you download from the History Center, you get the datas from MetaQuotes : those datas are NOT filtered by any broker, that's why any scalping strategy works very well. But now, no more broker is enough stupid to let you run those strategies. The History Center is simply useless.
Backtest Differences
Hi, i see the same differences with my EAs, but there is an interesting thing:
I forwardtested my EA from 2007-1-12 to 2007-1-13 , having a profit of 5k (usdmore - usdless), then i backtested the EA from 2007-1-12 to 2007-1-13 (same day as forwardtest) first in the build 198 then in the build 201, the results:
Build 198: 14k (three times more then forwardtest!)
Build 201: 600usd (1/10 then forwardtest!)
Forwardtest: 5k
Well, backtests let me a little confused, that one made with the Build 198 isn't correct (!!!) and that other one made with the Build 201 isn't surely correct (!!!), the only way to give a real reliable backtest result is to let the backtest run on real tick movements data (the data can be recorded and downloaded from mt4 like it's done now for m1-data, m5-data, etc..), i know this can take a lot of GigaBytes of historical data, but i hope that metaquotes will think about it soon, if we are trading to seriously make moneys, it isn't some GBytes of data that scary us :P
Be happy!
