```
usage: rsi [-l N_LENGTH] [-s N_SCALAR] [-d N_DRIFT] [--export {csv,json,xlsx}] [-h]
```

The Relative Strength Index (RSI) calculates a ratio of the recent upward price movements to the absolute price movement. The RSI ranges from 0 to 100. The RSI is interpreted as an overbought/oversold indicator when the value is over 70/below 30. You can also look for divergence with price. If the price is making new highs/lows, and the RSI is not, it indicates a reversal.
