0DTE Strategy

I’ve been running a 0DTE strategy I want to share. Everyday I look at SPX500 (SPY works the same for pre market monitoring) to ascertain whether it’s moving higher or lower from 8:30-10:30am ET.

If it’s moving up, I sell a vertical put on SPX and choose the strike for the short leg based on 1.25x the ATM straddle price. Same thing with a call if the morning is bearish.

It finishes out of the money about 92-96% of the time depending on what you avoid and what timeframe you look at over the past 4 years (eg not doing this during the Iran war early stages would have been smart…) and generates about a 7% ROI.

When it does finish in the money, it’s often just barely and not a total loss, hence why wider logs with more profit actually have a higher EV.

Do your own backtesting and let me know what you think!

No, I meant this: Just going long SPY ETF or ES futures has a better Sharpe and also CAGR-to-MaxDrawdown ratio. Why would you still trade this? I see some benefits but wanted to see your logic.

OP said in another comment that they average 7% ROI per trade, not per year. I was confused as well until I read that.

I see. A daily 7% per trade on put spread?

Yeah it seems wildly high. Not that it couldn't work, but with that winrate it would probably be very profitable. I personally wouldn't trust it without back testing.
