Market becomes a ruthless teacher today.

Market today was in ferocious ruthless form today. Overheated RSI sometimes stays overheated for few days or weeks and sometimes like today cools off in a day. Yesterday the RSI was above 70 and today it is below 30 on the hourly chart. 21550 is a good support zone from where we can see recovery but it is less likely possible point of reversal. The possible point of reversal can be 21450 and 21397. If 21397 is broken the next supports levels will be at 2133, 21188 or 20999. On the upper side the resistances will be at 21687, 21754, 21796 and 21847. It looks like the start might be negative but later in the afternoon or Friday Nifty can try to stage a recovery.
