What exactly is the difference between the formulas

 AVG(BOP5,10)

AND

BOP5.10

BOTH PROVIDE A RESULT BUT SOMEWHAT DIFFERENT GRAPH.

I wanted to create a PCF which provided the 5 day average of BOP as it was 10 days ago.

More generally, what exactly is the difference between using the comma and the period?

thx

Rob

AVG(BOP5,10) is the 10-Period Simple Moving Average of the 5-Period Simple Moving Average of Balance of Power (BOP).

BOP5.10 is the 5-Period Simple Moving Average of Balance of Power (BOP) from 10-bars ago (which is what you seem to actually want).

A , is used to separate the arguments in a function while a . is used to sparate the arguments in an indicator or as a decimal point (at least when using US regional settings).
