I would say that you should start backtesting the ma example strategy from the expert advisors example page
http://www.molanis.com/products/molanis ... rs-for-mt4Your ma conditions seem fine but using periods 3 and 5 does not make too much sense (unless you try to scalp) - One period should be longer.
Your iosma conditions are wrong. You need to compare the indicator with a number and not to itself
You said it: "buy signal above zero line and a sell signal below zero line." so you should compare it to zero.
Again, look at the examples, I think the rsi example compares the indicator to a number.
Also, it qould be better if you test first the ma and the iosma separatedly to make sure they work, and they join them
