Trends

Trend indicators help identify the direction and strength of a market trend. Moving averages are the most common type of trend indicator, smoothing out price data to create a clearer picture of the underlying direction.

Indicator Full Name Description
ALMA Arnaud Legoux MA Uses Gaussian distribution weights to balance smoothness and responsiveness.
