@Virajsemwal, Good question which u have asked. Appreciate you.. Small correction RSI 80 is overbought. And its depends on ur periods setting and time frame. if RSI 14, 30 and 70 levels are taken to consideration and if RSI 7, 20 and 80 levels are taken to consideration. Give u one more clue on RSI, Watch out the 61.8 is good buy and 38.6 on down side, it's based on Fibonacci levels. Time frame also a matter. Not only RSI, Even all indicators will get fail on strong news especially on result day. Happy Trading..!
