To the traders who are asking for MQL5 version, here is the code that you can copy paste into your MQL5 MetaEditor. note I just modified the code to work on MQL5 only colors were changed and timing windows were changed, EVERY THING belongs to the original author (KimIV). NOTE: the session timings in right now are based on FTMO America servers, you'll have to convert it to your own timings. but I only use New York time. Asia- 8pm - 11pm | London 11pm - 2am | NewYork 8am - 11am. GOOD LUCK.
