two macd strategy

[mojijan76]

hello guys
I want to create an expert by using two macd.
fast macd is:
6=fast period ,13=slow period and 9=signal period
slow macd is:
135=fast period ,390=slow period and 9=signal p..
if slow macd cross above zero line and then for first time fast macd cross below zero line buy signal be created.
I can't create an appropriate loop for this strategy
i shared my strategy:

Why have you got a loop? to put it simply if slow is > 0 and fast x< 0 your basic conditions are met, get this working, then you can add logic to prevent trades if wanted.
