How is the look back period determined

There are six adaptive methods in Adaptive RSI, all works in the similar way. In ranging, sideway, swing, choppy, and oscillating market, the look back period tends to be shorter. In trending market, the period tends to be longer. The stronger trend, the longer period. The weaker trend, the shorter period. With this mechanism, in trending market, Adatpive RSI is less likely to change its direction so we can ride on the trend for longer time. And in ranging market, Adatpive RSI will change its direction more often so that we can either catch the upcoming trend early or catch each reversals in the market.
