Momentum
The momentum indicator is a technical analysis tool used to identify ongoing trends and their remaining strength. It graphically represents the strength of a trend based on the relationship between the current price of a security and past prices.
It does not provide specific directional indications, so its value can indicate either a buy or sell signal; it merely estimates the probability that the current trend will continue. Generally, it is not used to generate primary trading signals, but to confirm signals produced by other indicators or chart movements.
