Hello, Step ONE: REMOVE the for loop. It is used incorrectly in your formula.
STEP TWO for starters: Don't put array functions inside loop. AFL is array processing language and you really NEED to read "Understanding AFL" first: http://www.amibroker.com/guide/h_understandafl.html STEP THREE: Buy needs to be ARRAY that has 1 (or true) for bars when you are entering the trade. Your code actually overwrote Buy array NumberOfBars-times with scalar zero or one.
