NIFTY 50 "Cypher Harmonic pattern"

Since several months Nifty 50 on Expanding Triangle, recently it tried to breakout but it starts to retraced to the correction, hence it formed a "Cypher harmonics pattern" and i expecting the massive reversal for the coming weeks, as im expecting the targets below

Target 1 - 17582
Target 2 - 18091
Target 3 - 18917
