I'm trying to deteremine the max of the standard deviation for a given period over the same period. Below is my code:
double v1 = StdDev(stdevPeriod)[0];
double v2 = MAX(v1(), stdevPeriod)[0];
however i get the error 'v1 is a variable but is used like a method'.
If I don't use the parenthesis with v1 I get the other error 'invalid arguements' and 'cannot convert from double to dataseries'
could someone help me with this???
thank you for help.
