R/S is a indicator invented by Hirashima Sugita. The purpose of R/S is to provide automatic Support and Resisstance lines.
A short period length adapt the indicator for short terms Supports and Resisstance and long period length to long terms support and resistance. Hirashima Sugita dont recommend to use this indicator for trade channel breakout. I tried to remake this indicator but it can be incomplete, some functions of the original indicator are too complex for me.
I think the indicator work well with all markets and time frames but feel free to modify the indicator if you want.
