About the Indicator
Although the indicator does nothing more than it says on the tin, There are a couple of points worth mentioning:
- The indicator will let you view up to 4 SMA’s
- You can set the period for each independently
- You can set the resolution for each independently (So you can see the see the daily level when on the 15-minute chart for example)
- Each can be turned on/off independently to avoid clutter.
