Intraday S&P 500 Gap-Reversion Strategy with Daily Levels

Summary

This strategy description proposes trading intraday reversals around levels derived from daily bars. It buys when price is below a recent daily low and sells short when price moves above a recent daily high, aiming to capture a return toward the prior day’s close. The example limits entries to a stated trading window, permits at most one long and one short entry per day, and uses stop distances based on the previous daily range. Positions are closed when price crosses back through the prior close or at the end of the session, leaving the strategy flat overnight.

The post characterizes the approach as a mix of gap closure and mean reversion and says similar settings may be applied to other indexes, but it supplies no test results, sample period, or performance statistics to support that claim. The code’s entry conditions, stop settings, and timing depend on platform-specific behavior and should be checked carefully in a backtest. Spread, slippage, contract sizing, and the risk of moves continuing away from the entry level could materially affect results.

Key ideas

• The strategy enters long below a recent daily low and short above a recent daily high.
• It seeks reversion toward the previous day’s close and exits positions before holding overnight.
• Entry frequency is limited, and stop distances are tied to the daily range.
• The document provides no performance evidence, and execution costs or platform behavior may change outcomes.
