Risky short Last week high as resistance duration for first half of the day 0.5% low , if open gap up of 0.3%... This will be the ideal scenario to short build up from 9.30 to 10.00 Am if opens gap up and sustain for 45 min. however there is a long build up at 17500 ce 63 (16sep expiry)... and it may reach 80 to 90 tomorrow.
