EMA
Also known as: Exponential Moving Average
The Exponential Moving Average (EMA) is a type of moving average that places a greater weight and significance on the most recent data points.
Plain-English Meaning
Like a regular moving average, the EMA smooths out price action. However, the EMA reacts much faster to recent price changes because it gives more mathematical importance to what happened recently compared to what happened weeks ago.
Why It Matters
Because the EMA hugs the price more closely than a simple moving average, traders use it to spot trend changes and reversals much earlier. It is highly popular among day traders and swing traders.
Simple Example
If sudden news causes the price to jump, a 20-period EMA will curve upwards to reflect this new momentum much faster than a standard 20-period Simple Moving Average.

Beginner Mistake
Relying solely on the EMA during volatile events. Because it reacts so quickly, sharp, temporary price spikes can cause the EMA to give false signals before the trend actually reverses.
