RelativeStrengthIndex

Summary

The RSI (Wilder) is momentum oscillator, measuring the velocity and magnitude of directional price movements.

Remarks

The RSI is most typically used on a 14 day timeframe, measured on a scale from 0 to 100, with high and low levels marked at 70 and 30, respectively. Shorter or longer timeframes are used for alternately shorter or longer outlooks. More extreme high and low levels�80 and 20, or 90 and 10�occur less frequently but indicate stronger momentum.
