Nifty _ Tough Resistance at 15865

Nifty has to get back into the channel for an up-move to 16000. To do this there is a stiff resistance at 15865 once it enters the zone above 15800. It needs to close above these levels , sustain and then attempt to touch 16000 which may further go to touch 16150 - 16200. At the same time , 15865 can also be a shorting opportunity with a 15 minute close above this level.
