This is what happened to me recently.
I was running 2 EA's on separate charts and within a time span of 1 minute the EA's lost over $1000. The losses were small ranging from
$1.25 to $2.50 each. When I backtested each EA independently they showed overall winning behavior with high profit factors >10
and low drawdowns <5%. At this point I don't understand why the trades occurred. I am wondering if anyone can give me
some clues as to what to look for or how to duplicate with backtesting. I would be happy to share the EA's if this might help diagnose the
issue. I am hoping someone has seen this before and can point me in the right direction.
You have to write down all the operations your EAs are doing and the conditions under which they are doing it in the log file, so you can know the
why of things.
