Nifty has been seeing a corrective decline, within the parallel channel from last 10 trading session, we can observe currently it has hit and crossed upper end of channel slightly. but the decline from lows has been 3 wave. Also we are not getting follow through buying ...which normally happens when we make channel break out. Hence i feel, nifty would still remain within the channel and probably. move to lower end of channel again.
I wouldn't short though , but will wait for lower levels to come again to go long.
