Today Nifty opened flat and we saw a sharp down move towards 21450 but it didn't sustain below 21470 which was our sell level, after consolidating near 21500 - 21470 support zone we saw a good rally in afternoon session.
For tomorrow, if Nifty sustains above 21640 we expect to see upside towards 21680 and upper marked levels. On the down side, Nifty has to break 21450, which can take Nifty towards 21410 and lower levels. Range is bigger for tomorrow in Nifty weekly expiry, trade cautiously.
