The main moving average periods to focus on are 21, 55, 100, and 200. Shorter-term traders may consider looking at the 9- and 14-period moving averages.
I read the above in a book. What does it mean? I would love some clarification on this. What are moving average periods?
The ‘21, 55, 100, 200’ define how far back the MA is being calculated.
If you’re looking at an H1 chart and plot a ‘[I]100 SMA[/I]’, it’ll use the last [I]one hundred[/I] 1-hour bars for its calculation.
If you’re looking at an M15 chart and plot a ‘[I]55 SMA[/I]’, it’ll use the last [I]fifty-five[/I] 15-minute bars for its calculation.
