DeployQuantRSI (Relative Strength Index)
A momentum oscillator that scores the speed of recent price changes on a 0–100 scale. Readings below 30 are conventionally called oversold and above 70 overbought. RSI is computed from average gains versus average losses over a lookback window — 14 periods in Welles Wilder's original version. Mean-reversion strategies buy low RSI readings expecting a snapback; trend traders instead read persistent high RSI as strength.

Backtests are hypothetical, computed by DeployQuant's engine on minute-resolution consolidated US market data (2021-01-04 to 2026-10-02, $10,000 starting capital, no margin, no fees or slippage in the headline run; buy-and-hold puts 98% of the account in at the first open, as the templates do) and do not guarantee future results.
