Momentum Indicator

momentum📊 1H, 4H, Daily

Measures the rate of price change by comparing current price to price n periods ago.

Formula

Code

Momentum = Close - Close(n periods ago)

ROC = ((Close - Close(n)) / Close(n)) × 100

Detailed Explanation

The Momentum indicator is one of the simplest technical indicators, measuring the rate of price change.

Two Forms:
1. Momentum: Absolute difference (Close - Close[n])
2. Rate of Change (ROC): Percentage difference

Usage:
- Rising momentum confirms uptrend strength
- Falling momentum warns of potential reversal
- Zero-line crossovers signal trend changes
