A dilemma to this is that a lot of supports lie in this 10510-10570 range and hence there is a chance that nifty might bounce from here. So it is advisable to nibble and take small trades and see how the trade pans out at day's close tomorrow.
Do not overstay your welcome in either direction.
Note : It would be wise not to sell if nifty opens below 10590 tomorrow.
Also the high probability trade of selling did not work out. But as suggested if one would have nibbled on the short trades there was money to be made on the ranges of the Bollinger Bands. It was eventually taken out in the final half an hour.
