Option testing tools

Hello, Can you suggest how to back test option selling strategy where the put/call and strike would be decided based on high low of the daily live candle at 2 pm.
It means whether to sell put or call and strike price would be decided dynamically based on the parameter at certain time of the day.
Your advice / insight would be useful.

Thank you

can you maybe explain more on this with an example? if i get better clarity i can probably suggest you, i have tried couple of platforms rigorously
