Nifty Showing weakness and near important support level.

Nifty was repelled from the resistance zone near 21768 and got thrashed throughout the day as RSI had to cool down. Further downside is possible if support zone of 21500 to 21425 is broken. In this case further down side upto 21389 or 21235 is possible. The worst case scenario as of now looks near 21143. In case 21143 is broken Bears can strengthen their grip and bring the index under their control. Resistances zone on the up side is between 21593 and 21613. Further upside upto 21686 or 21768 can be seen in case we are able to close above 21613 level.
