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
The textbook 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 the washout at the next session open and holds until RSI crosses back above 70 — no profit target, no stop, just the oscillator round trip.
Good for: assets that trend up over time but overshoot on the way — broad index ETFs are the classic home.
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 5.5 years of minute data in seconds, tweak any parameter, then paper trade it on live data. No card, no broker needed to start.
