Theory : We have all sorts of RSI : regular rsi, rsi of averages, .... so far we did not have an RSI of SAR (Parabolic SAR). Here is this version : instead of using prices, it is using parabolic SAR. Results are interesting and are not lacking logic, hence decided to post it here PS: the RSI used in this calculation is the one using double smoothed Wilders EMA instead of "simple" Wilders EMA. Results are a bit smoother (and faster) this way
