Yep... These MT4 testing anomalies are well documented here on this board, with a number of different EAs, and are well documented elsewhere. Historical data from different sources with different price quotes, various brokers handling Sunday bars differently producing dramatic differences in outcomes, history files becoming a corrupted mix of different data sources, some downloadable historical data is generic instead of your brokers data, errors caused by backtesting models, holes in the downloadable history data, different start dates and times producing different trading sequences, different EA settings producing significantly different results in a given time period, different broker handling of lotscales and account-type (ie., FXDD and IBFX), etc. etc. All of this stuff has been reported by users at various times.
These Dreamteam posts describing different results are like deja vu all over again.
Here's a little fun reading:
You know what I love... It's the first link that popped into my head. There are many threads describing various aspects of this problem. (These problems...)
After absorbing the fix for the data problem described in the you-know-what-i-love thread, you can contemplate the idea that the solution given in the thread is great, IF you are
trading on Alpari data. Otherwise, your next step is to figure out if your broker handles Sunday bars the same way as Alpari, if they quote the same prices from minute to minute, etc. On and on it goes...
After that you can check out the Phoenix thread and see the effect of different start times...
Hmmm... at the bottom of this page we have this link: "USDCHF corrupted data from neuimex"

While it's reasonable to expect and assume accuracy and uniform results from MetaTrader, that ain't necessarily what you're gonna get.
