Then order of types of function arguments is.... array, string, float

As aside NthHighest function has been posted few months ago (and same there... order of arguments doesn't matter).

Function of Nth highest function in AFL

Your code is wrong as it returns wrong values (see table below). And yes, there is simpler way by just using Percentile function outputting correct values function NthHV( array, period, nth ) { return Percentile( array, period, (period-nth) / (period-1) * 100 ); } Period = 30; HighestValue = HHV(H, Period); NthHighest = NthHV(H, period, nth=2 ); Filter = 1; format = 1.2; AddColumn(H, "High", format ); AddColumn(HighestValue, "HighestValue", format ); AddColumn(NthHighest, "NthHighestVal…
