On Monday 13th Aug 2012, it is better to go long above 5330 with SL of 5318. Expecting market up in first half and would go down in 2nd half most probably from 5350-60 level. This could be the day when market will decide future course of action.

Expiry Logic

If the prices are trading below 60% mark of its range for the settlement, bulls are weak and the settlement will end closer to the lows, often, making a new low for the settlement day.

And vice versa for upmoves/ bulls.

ATR Formula

PC-ATR*.80 to PC-ATR*0.50 Buy Zone
PC+ATR*0.50 to PC+ATR*0.80 Sell Zone
where PC is previous day's close.

Bears get weak near PC-ATR*0.50 to PC-ATR*0.75, 
but get charged up below PC-ATR*0.80 for a target of DH-1.5*ATR

Bulls get weak near PC+ATR*0.50 to PC+ATR*0.75, 
but get charged up above PC+ATR*0.80 for a target of DL+1.5ATR

where DH & DL are current days High & Low respectively.
