Backtesting 0DTE Options Strategies: What the Data Shows

Opinions about 0DTE trading are everywhere. Data is scarcer. Here are actual backtesting results for the most popular 0DTE strategies, run against historical options data with realistic assumptions about fills and commissions.

Methodology

All backtests use these parameters:

  • Underlying: SPX
  • Period: January 2020 – December 2025 (6 years)
  • Starting capital: $100,000
  • Commissions: $0.65 per contract
  • Slippage: $0.10 per spread (conservative assumption)
  • Entry time: 10:00 AM ET
  • Days excluded: FOMC announcement days, CPI release days

    • Strategy 1: 10-Delta Put Credit Spreads

    Setup: Sell a $5-wide put spread at the 10-delta short strike daily. Exit: Close at 50% profit or 2x credit loss. Hard close at 3:45 PM.

    | Metric | Result | Total trades1,425 Win rate81.3% Average win$68 Average loss$312 Annual return22.4% Max drawdown14.7% Sharpe ratio1.52 | Profit factor | 1.38 |

    Takeaway: The workhorse strategy. Consistent, boring, profitable. The max drawdown occurred during March 2020, but the strategy recovered within 4 months.

    Strategy 2: 10-Delta Iron Condors

    Setup: Sell a $5-wide put spread and $5-wide call spread, both at 10 delta. Exit: Close at 50% profit or 2x credit loss on either side.

    | Metric | Result | Total trades1,425 Win rate73.6% Average win$125 Average loss$380 Annual return19.8% Max drawdown18.2% Sharpe ratio1.18 | Profit factor | 1.25 |

    Takeaway: Higher premium collected, but the call side gets tested more often than you'd expect. Strong trend days hurt. Slightly worse risk-adjusted returns than pure put spreads because the market's upward bias means the call side has more risk than its delta suggests.

    Strategy 3: Long ATM Straddles (Event Days Only)

    Setup: Buy ATM straddle 30 minutes before FOMC/CPI. Close at end of day. Filter: Only 12 FOMC days and 12 CPI days per year = ~24 trades.

    | Metric | Result | Total trades142 Win rate44.4% Average win$480 Average loss$285 Annual return8.2% (on allocated capital) Max drawdown22.5% Sharpe ratio0.68 | Profit factor | 1.19 |

    Takeaway: Marginally profitable but high variance. The wins are large (2–3x the straddle cost on volatile FOMC days), but many events produce muted moves that don't cover the premium. Not reliable as a primary strategy.

    Strategy 4: Opening Range Breakout (30-min)

    Setup: Buy the $1 OTM call on a break above 30-min high, or put on a break below low. Exit: 50% stop loss on premium, target at 1x opening range width.

    | Metric | Result | Total trades892 Win rate42.1% Average win$168 Average loss$84 Annual return14.6% Max drawdown16.8% Sharpe ratio0.95 | Profit factor | 1.34 |

    Takeaway: Lower win rate, but the average win is 2x the average loss. This is a momentum strategy that works well in trending markets and bleeds in chop. Adding a VIX filter (only trade when VIX is 15–25) improves the Sharpe to 1.15.

    Strategy 5: VWAP-Centered Butterfly

    Setup: At noon, buy a $1-wide butterfly centered on VWAP. Exit: Close at 3:30 PM or let expire.

    | Metric | Result | Total trades1,380 Win rate29.8% Average win$62 Average loss$24 Annual return11.3% Max drawdown8.4% Sharpe ratio1.35 Profit factor1.52

    Takeaway: Surprisingly strong risk-adjusted returns. The low cost of butterflies means losses are tiny, and wins are 2.5x losses. The low max drawdown makes this an excellent complement to a credit spread strategy.

    What Backtesting Can't Tell You

  • Execution quality. Backtests assume you get filled at theoretical prices. Real-world slippage, especially during fast moves, can erode 1–3% of annual returns.
  • Emotional impact. A 14.7% drawdown on paper feels very different from watching $14,700 disappear from your account in real time.
  • Regime changes. Past performance doesn't guarantee future results. Market microstructure changes as 0DTE volume grows.

    • Running Your Own Backtests

    The strategies above used OptionsPilot's backtesting engine with SPX data going back to the 1990s. You can replicate these results — or test your own modifications — by adjusting delta targets, spread widths, entry times, and exit rules. The backtester runs in seconds and requires no coding.

    The most valuable thing you can do before trading 0DTE with real money is test your exact rules against years of data. Not approximately — your exact entry time, your exact delta target, your exact exit rules. The gap between "this strategy generally works" and "these specific parameters work" is where most traders lose money.
