Nifty at 50 EMA support on the edge of a knife

Even DIIs booked some profit today. Also it was weekly expiry. Tomorrow will be a key day for the rally to continue NIFTY is exactly and very rarely at 50 days EMA support of 17560...As it was mentioned in this tweet here. (The support level of 17555 was given last night).

Nifty has to close above this tomorrow to take the momentum to the next week.....
