The rules
Buy when the 14-day RSI drops below 30 (oversold), sell when it recovers above 70 (overbought).
- WHEN the market opens · IF not invested AND RSI(14) < 30 · THEN buy with 98% of the sleeve
- WHEN the market opens · IF invested AND RSI(14) > 70 · THEN sell the whole position
A standard mean-reversion setup. The Relative Strength Index measures how stretched recent price action is. Readings under 30 have historically marked short-term washouts in uptrending assets. This template buys at the next session open and holds until RSI crosses back above 70. It has no profit target and no stop.
Good for: assets that trend up over time but overshoot on the way, such as broad index ETFs.
Watch out: in a persistent downtrend, RSI can stay oversold for weeks while the position keeps losing; there is no stop-loss in this template.
Build it from blocks (or type it in English), backtest it on 5.7 years of minute data in seconds, tweak any parameter, then paper trade it on live data. No card, no broker needed to start.

Over 2021-01-04 to 2026-10-02, RSI mean reversion on SPDN returned −4.0% annualized vs −9.7% for buy-and-hold: it beat buy-and-hold by 5.7% per year, with a maximum drawdown 17.6 points shallower than holding (28.5% vs 46.2%).

Why RSI 30/70?
They are the conventional oversold and overbought bands from Welles Wilder's original formulation. Treat them as a starting point. In DeployQuant you can change them to 25/65 or anything else and re-backtest in seconds.
Does this strategy use a stop-loss?
No. The only exit is RSI recovering above 70. Adding a stop or a take-profit block is a one-block edit in the Lab.
