This is an early version (2015) of Mladen Rakic Schaff_Trend_cycle_zones.mq4.
Expect the teacher to replace the original algorithm with the Composite RSI (RSX) algorithm and make a Schaff_Trend_Composite RSI (RSX)_zones.mq4. Further improve the accuracy of the zones version.
Boundless merit!
(The main chart in the chart is M30 minutes zones, and the technical indicator window is M5 minutes)
