This is one of the very good video on a forex indicator called momentum indicator that I got today and would like to share with you. I almost don’t know how to use this indicator until I watch this video. Momentum indicator is a leading indicator. Momentum measures the rate of change in the closing prices for a currency pair. It is often used to defect weakness and likely reversal points. High momentum readings occur when a trend is at its strongest. Lower readings are found at the start or end of a trend.
