RSI Mean Reversion

What It Does

RSI Mean Reversion runs on a single contract at one timeframe. On every bar close it computes the current RSI value over the configured period and compares it to four thresholds: an oversold level, an overbought level, a long-exit level, and a short-exit level.

• If the strategy is flat, the side is long-only or both, and RSI crosses down through the oversold level, it goes long at the close.
• If the strategy is flat, the side is short-only or both, and RSI crosses up through the overbought level, it goes short at the close.
• A long position exits when RSI crosses up through the long-exit level.
• A short position exits when RSI crosses down through the short-exit level.

Crossover detection is symmetric. The strategy tracks the previous bar’s RSI and only fires when the line moves through the threshold; sitting below the threshold for multiple bars produces one entry, not a stream of them.

There are no stops, no profit targets, no trend filters, no position sizing beyond a fixed contract count. The RSI cross is the only exit. Holding period is whatever RSI takes to mean-revert.

Why It Works (Sometimes)

Mean reversion at short horizons is one of the better-documented edges in liquid equity indices. After a sharp move down, the next day’s return is on average slightly positive; after a sharp move up, the next day is on average slightly negative. Larry Connors codified this with RSI-2 in the mid-2000s, and the pattern has held up reasonably well in equity index futures since.

The edge is small, the variance is large, and the strategy can chain a string of winners before a single big trend move erases them. RSI mean reversion strategies tend to look great until they don’t, and the “don’t” usually coincides with a regime change to trending markets. The presets here are the textbook starting points; before relying on any of them, run them through a regime that matches what you actually trade.

Presets

Five presets cover the canonical variants:

• Connors’ RSI-2 Long / Short: the original short-term setup. Fires often (typically 10-30 trades per year on a daily contract), short holding periods, high win rate, ugly tail.
• RSI-14 Oversold Long / Short: the textbook slower variant. Fires rarely, holds longer, less prone to whipsaw.
• RSI-7 Two-Sided: a middle ground that takes both long and short entries off intermediate RSI extremes.

Use the form to set your own period and thresholds; the presets are starting points, not endpoints.

Best In

• Mean-reverting regimes. Range-bound markets, post-shock reversion, post-event chop.
• Liquid equity index futures (NQ, ES) where the mean-reversion edge is best documented.
• Research where you want a clean, well-known baseline to compare a more sophisticated mean-reversion idea against.

Where It Struggles

• Strong directional trends. RSI-2 in a bull market will short overbought spikes that keep going up; long-only variants avoid this side of the failure but still get smaller wins.
• Single-sided regimes that last for months. The strategy has no regime filter; it will keep entering whether the setup is working or not.
• Markets with persistent skew (commodities in a structural backwardation, for example). The two-sided preset can be especially exposed.

Possible Uses

• A control strategy when evaluating other short-term reversion ideas: any setup whose returns track RSI-2 long is not adding much.
• An honest stress test of the “mean reversion” thesis on whatever contract and timeframe you care about. The same parameter set can be sampled across regimes.
• A starting point for layered strategies. RSI dips combined with a regime filter, or with a volatility filter, or with a position-sizing rule, often produce more usable backtests than the bare strategy does.

What It Does Not Do

• No stops, no targets, no time exit. If RSI never crosses back through the exit threshold, the position is held until the strategy is shut down.
• No volatility-adjusted thresholds. The same oversold value applies across calm and chaotic regimes.
• No re-entry while in position. Once a long is open, additional RSI dips below oversold are ignored.

FAQ

Does RSI mean reversion actually work?

RSI mean reversion captures the tendency of short-term price extremes to snap back toward a neutral level. It tends to work in choppy, range-bound conditions and to struggle when a market trends hard and stays oversold or overbought for a long time. Whether it is profitable depends on the contract, timeframe, and thresholds. Run the backtest to see the win rate and profit factor for your settings.

What RSI settings does this strategy use?

It compares the current RSI to four thresholds: oversold for long entry, overbought for short entry, and separate long-exit and short-exit levels. The classic short-term setup uses a low RSI period with deep oversold and overbought levels, the shape behind the well-known RSI-2 idea. The form lets you set the period and all four thresholds.

Is a high win rate from RSI mean reversion reliable?

Mean reversion strategies often show high win rates because they exit on a small bounce, but the occasional trade that keeps going against the position can erase many small wins. Look at average win versus average loss and the drawdown, not the win rate alone. The backtest on this page reports all of them so you can judge the trade-off honestly.
