Re: [amibroker] Could someone point in the right direction...

["Steve Dugas" <sjdugas@xxxxxxxxxxx>]

Hi - In 2nd arg of for loop header, you are assigning a value of zero 
instead of testing for it, so I am guessing the expression returns zero and 
so is never true. Might be easier to do this without a loop, something 
like...

InTrend = AlligatorGreen > AlligatorRed AND AlligatorRed > AlligatorBlue;
NotInTrend = NOT InTrend;
TrendBars = BarsSince( NotInTrend );
