GMS: % True Range

This just give the range based in % so it can be easily compared to the past. The default setting gives the % range high to low for the current session.

This is what I originally wanted as a 1 period ATR gives it in price points and ROC only does current close to previous close. With this you can select OHLC for the two prices you want to use as well as length.

I hope it helps!
