# EMA ## EMA An exponential moving average (EMA) is the weighted average of a set of data points where new data points receive greater weight in the average calculation. An exponential moving average is a technical indicator of a trend that responds faster to new data points than a simple moving average because a multiplier is used to give preference to the new data points and reduce lag in responsiveness to price movements. The source code for the EMA function is available [here](https://app.optionalpha.com/ta/EMA.txt). --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
