I'm constantly tinkering with the Delta for my strikes and the width of my wings for my 45-60 DTE trades.
There is not much to go on here as far as reward to risk tolerance.
It is a long process starting with backtesting.
We have 10 million backtests just for SPY to get a sense of how this strategy may work out.
We test with varying DTE, deltas, spread price/stock price, and options environments levels: VIX, SMA, RSI, IVpercentile, and skew.
For example now we are in a moderate VIX, stock >200SMA, stock<50SMA, oversold RSI, high IV pctl, and high slope environment for SPY.
You can view how your strategy does in any combination of two of these parameters.
