TRADING GLOSSARY

EMA (Exponential Moving Average): responsive trend tracking

An Exponential Moving Average gives more weight to recent prices and less to older prices, making it more responsive to current price action than a Simple Moving Average (SMA). This faster response time makes the EMA the preferred moving average for many active traders.

How EMA is calculated

The EMA uses a multiplier that gives exponentially more weight to the most recent data: Multiplier = 2 / (Period + 1). For a 20-period EMA, the multiplier is 2/21 = 0.0952, meaning the most recent price gets about 9.5% weight. Current EMA = (Current Price × Multiplier) + (Previous EMA × (1 − Multiplier)).

Popular EMA periods

9 EMA: Short-term trend on daily charts. 21 EMA: Intermediate trend, popular for swing trading. 50 EMA: Medium-term trend. 200 EMA: Long-term trend — often treated as the boundary between bull and bear territory.

EMA trading strategies

EMA crossover: When a fast EMA (e.g., 9) crosses above a slow EMA (e.g., 21), it signals a bullish trend change. The opposite signals bearish. EMA as support/resistance: In strong trends, price often bounces off the 21 or 50 EMA. Price-EMA relationship: Price above the 200 EMA = bullish bias. Price below = bearish bias.
