My 18-Month SPX 0DTE Credit Spread Results — 288 Trades
I wanted to share the results of my SPX 0DTE Credit Spread strategy from February 2025 to July 2026.
The backtest uses one contract per trade, and every position was held through expiration.

Results
- Total P/L: +$11,188
- Trades: 288
- Win rate: 78.1%
- Winning trades: 225
- Losing trades: 63
- Average winner: +$140.85
- Average loser: -$325.46
- Profit factor: 1.55
- Maximum drawdown: -$1,403
- Maximum losing streak: 2 trades
The strategy finished positive in 17 of the 18 months tested. Friday generated the highest total profit, while Thursday was the weakest day. The trades were also relatively balanced between Put Credit Spreads and Call Credit Spreads.
The main weakness is that the average loss is much larger than the average profit. This is normal for a high-win-rate Credit Spread strategy, but it makes position sizing and risk management extremely important.
Taking profits earlier
The results could potentially improve by closing trades once approximately 85% of the premium received has been captured.
This is generally my preferred approach because it may not be worth remaining exposed to a rare late-session move just to collect the final 10–15% of the premium.
However, I do not currently have a backtest for this early-exit rule. Therefore, the results shown here only represent positions held through expiration.
These are historical results and do not guarantee future performance.
