I have a question about calculating Moving averages. I'm curious to know how a 20 period 60 minute moving average is calculated? The reason I ask is because I have this software which does this, but not in the traditional manor it seems. It simply does not plot a 60 minute chart with a 20 period Moving average. The line mostly ressembles a 75MA on a 10 minute chart. I'm wondering if anyone heard of such calculations in trading?
