Straddle with adjustment

Dear Sir,

I want to make strategy as following.

Want to sell bank nifty monthly ATM straddle on starting of month in morning.

Example short straddle banknifty 36000 at 900ce and 900 pe.

Break even point is 34200 and 37800.

If banknifty move 450 point ( 1/4 of my break even ) up then want to sell Bank nifty weekly 1000 point down to current banknifty spot price.

If banknifty move 900 point ( half of break even point ) then exit all positions and repeat short straddle.

If my lose become more then 2000 then exit all positions and repeat short straddle.

Profit 12000 then exit.

Please help me to built this kid of strategy.
