Reliance has been a true star that practically carried Nifty for some time. Now it's time for a breather. The rally looks tired. Notice the indecisive price action at 1600 level (encircled). Also there is divergence in the stochastics as seen in CCI. Should be a low risk trade to go short with a stop above 1620 and target of 1505 (just before 1500 to be safe)
