Periods Skipped in Backtesting

Recently discovered that my metatraders skip dates, seemingly at random when backtesting, sometimes it will be weeks at a time. No reason in the code for this. Looked for data errors, and tried different data, no luck.

Any reason for this people know of, apart from metatrader being a bit rubbish?

Also, the ea will sometimes still trade in this period, but not post anything in the journal or anything.

Thoughts?

cheers.

BUMP.
