Having a strange problem backtesting an EA I made in Meattrader 4’s strategy tester. It stops making trades after about 8 months, no matter what dates I test.
For example, I run it for 2008 to 2012. It will make trades for the first 8 months of 2008, but then then run no more trades all the way through til 2012. If I start the next test where the last one stopped trading (Aug 2008), it will trade for another 8 or 12 months, then stop again.
The only solution so far is to test 6 months at a time. But that’s not fixing the problem. Something is wrong here. Any ideas what it might be?

Nevermind. I downloaded history data from another source and now it works 
Aside from what you just encountered, here’s some more things to look out for in the future that would cause an issue with a backtest.
[ul]
[li] Unrealized loss maxes out usable margin, stopping any further trades.

[ul]
[li] EA uses pending orders, and one is left open, mitigating any further trades.

[ul]
[li] Incorrect date for start of test.

[ul]
[li] Conflict in code that compiles correctly, but isn’t possible. usually in the < or > area, but sometimes order related.

These are just a few I’ve encountered along the way, but are by far the most frequent offenders.
It’s tricky figuring out what went wrong sometimes, so thanks for the tips. Duly noted.
