If you want to delay based on bars in the actual test period you have selected, then maybe something like this might work
Buy = OtherBuyConditions and IIf(Status("action")>2,Cum(Status("barinrange"))>150,1);
If you just want to make sure there are 150 bars at the start of the symbol history then
Buy = OtherBuyConditions and BarIndex()>150;

Subject: Delay first BUY signal by x bars
To: amibroker@xxxxxxxxxxxxxxx
Hi,
if Buy= cross(ema(c, 15), ema(c,50))
then it is recommended that no signals be taken till (as a thumb rule) - Largest EMA * 3 periods
In this case how do instruct to postpone taking the first BUY signal till 50*3 =150 bars from the befining of test period?
Do I do something like - iff(barindex() <=300, buy=0, buy) ??
Sorry if the code looks clunky - I am an absolute rookie and I have just written my first system AFL today. Still figuring if it works the way i intended it to! B-). But Amibroker rocks!
TIA
