Nifty 50 Moves Identification for the Intraday of 21st February
I have marked two Important levels for today's trade setup.

First: Based on the Pull back, the Key resistance for the Intraday (17,920)
Second: Based on yesterday's swing low. Breaking this level is a sign the trend will continue (17,780)

Both levels are sell levels, either on pullback or continuation. The long can be considered above 17,950
