At a first glance it seems to be usable - further testing needed though. It is also showing that if metatrader 5 code is used as it should (without attempts to have metatrader 4 equivalents) the code is much simpler and much faster then the code that is starting to float around (and which is hard to recommend to anybody to use). Old threadHere is double stochastic rsi - metatrader 5 version. It uses floating levels.
In case of setting rsi period to 1, then you get double stochastic of rsi.
