1. SMA: Simple Moving Average

A simple moving average is the arithmetic average of closing prices over a period. A 20 SMA averages the latest 20 candles.

2. EMA: Exponential Moving Average

An exponential moving average assigns greater weight to recent data, making it more responsive to price changes.

3. Main differences
