Hmm, IDK, but now I remember where I have seen this part of a strategy before. Elliott Waves. The idea is that when the oscillator reaches the OB/OS level and returns, the impulse wave is over. But keep in mind it is just a confirmation for EWs or maybe another strategy, no strategy itself. You would have to filter Zigzag and Stoch/RSI.
