Interesting idea from
@dhirajsinha sir
Sell 20 Delta Strangle at 9:16 AM.
Exit if either leg reaches 50 Delta (30 pts SL).
We were curious, so we backtested it on NIFTY (0 & 1 DTE) with slippage, taxes & charges included.
Results were surprisingly consistent across multiple years.
Also, this is exactly why we
@AlgoTest_in recently launched Delta Based SL, Target & Trail SL on AlgoTest.
Curious — how many of you manage option positions using Delta instead of premium-based SLs?
Here's an non directional strategy and the formula for deciding the position size.
Strategy - Short strangle, sell 20 delta at 9:16 am with 30 delta SL on each leg (basically exit if a leg becomes ATM). Else exit at 3:25 pm
Win % 64, R:R 0.82
So, as per Kelly, position size is
(0.82*0.64 - 0.36)/0.82 = 0.2
So, 20% of the capital.
In the context of Nifty I will use only 20% of the margin I have to run this strategy. Approx 1 lot for 10 lacs margin.
Disclaimer- strategy is given only to illustrate position size.
