ROC SAR

The ROC SAR indicator is nothing more than the ROC indicator applied to all Orion averages: 17, 34, 72, 144, 305, and 610.
It features alerts for possible pullbacks.
Bullish pullback: ROC 17 below the 0 line with all other ROCs above 0.
Bearish pullback: ROC 17 above the 0 line with all other ROCs below 0.
Colors and thicknesses can be adjusted to your liking.
It comes with a default period setting of 5; I recommend changing it to 3 periods, I think it works better, but it’s up to your trading style and preference.
