Is RSI 14 the best setting?

RSI 14 is the default and works well for most situations. Shorter periods (7-9) are more sensitive, longer periods (21-25) are smoother.

Can RSI stay overbought for a long time?

Yes! In strong trends, RSI can stay in overbought/oversold territory for extended periods. This is why divergences and trend context matter.

momentum📊 15M, 1H, 4H, Daily

RSI measures the speed and magnitude of price changes, oscillating between 0-100 to identify overbought and oversold conditions.

Formula

Code

RSI = 100 - (100 / (1 + RS))

RS = Average Gain / Average Loss over period

Detailed Explanation

The Relative Strength Index (RSI) is a momentum oscillator developed by J. Welles Wilder Jr. in 1978. It measures the speed and change of price movements on a scale of 0 to 100.

Key Levels:
- Above 70: Overbought territory
- Below 30: Oversold territory
- 50 Line: Centerline, indicates trend direction

Trading Applications:
1. Overbought/Oversold: Trade reversals at extremes
2. Divergences: Price vs RSI disagreement signals reversals
3. Failure Swings: RSI pattern that can precede price reversals
