Title: AFL drives me nuts

Yep you’re right.  I always thought Null was 0.

anything that is added to NULL is null;

try result = 0;

This looks correct and logical to me, but it doesn’t work.

result = Null;

        for ( i = 1; i < BarCount; i++ ){

                High1 = High[i];

                High2 = High[i-1];

                Low1 = Low[i];

                Low2 = Low[i-1];

                if((High1 > High2 AND Low1 > Low2) OR (High1 > High2 AND Low1 == Low2)){

                        result[ i ] = result[i - 1] + 1;

                }else if((Low1 < Low2 AND High1 < High2) OR (Low1 < Low2 AND High1 == High2)){

                        result[ i ] = result[i - 1] - 1;

                }else{

                        result[ i ] = result[ i - 1];

                }

        }

        Plot( result, "Digger", ParamColor( "Color", colorBlack ), ParamStyle("Style"));

Thanks
