Until Nifty sustains below 10780 (weekly 100EMA), there is no short opportunity. On the other hand, there is no positive bias in the market to start an upward rally. At present Nifty is in a volatile sideways zone and it is better to stay out of the market till it closes below 10780 on a weekly basis. Protect your capital and wait for the right opportunity, even if that means taking no trades at all for several days!
