Re-entry on sl hit with difference between ltp and sl

[kgangaprasad29]

I created straddle.

1. ATM CE : premium - 120
2. ATM PE : premium - 120
3. If one leg sl hit with 25 % - 120*1.25 = 150 SL (Example CE hit SL)
4. I would like re-enter with difference 150-125 = 25 Rs CE
5. I have to find the strike which is having 25 premium using repair once condition and find strike condition.
   I need your help.
   Thank you.
