Short Straddle with Adjustment - Streak Strategy - Help needed

I am trying to run a short straddle strategy in bank nifty using streak. On hitting stop loss of 50 or target of 100, ATM leg at that moment should be sold. But the issue is after hitting stoploss or target, it is taking 1 minute gap to execute the next sell order. Is there any way i can pass the sell order at the same time of the stoploss or target?
