Exponential Moving Average (EMA)

What is it?

The Exponential Moving Average gives more weight to recent prices, making it more responsive than SMA. In swing trading, the relationship between price and EMA 20/50/200 defines the market structure. When price > EMA20 > EMA50, the trend is bullish. The EMA 200 acts as the long-term bull/bear divider.

Why it matters

EMA positioning carries the HIGHEST weight (2.0) in AIShare's signal scoring. It determines the overall trend posture — whether you should be looking for buys or sells. The Golden Cross (EMA50 > EMA200) and Death Cross (EMA50 < EMA200) are major regime-change signals.

Formula

EMA = Price(t) × k + EMA(y) × (1 − k), where k = 2 / (N + 1)

Key parameters

How to use

1. 1Plot EMA 20 (short-term), EMA 50 (medium), EMA 200 (long-term) on your chart
2. 2Price above all 3 EMAs = Strong bullish trend — look for dip-buying opportunities
3. 3Price below all 3 EMAs = Strong bearish trend — avoid longs or look for shorts
4. 4EMA crossovers (20 crossing above 50) signal momentum shifts
5. 5Use EMA 20 as dynamic support in uptrends — entries on bounces from EMA 20
6. 6Dips to EMA 50 in bull trends are classic swing trade entry points

Swing trading tips

• In a confirmed uptrend, buy pullbacks to EMA 20 or EMA 50
• If price closes below EMA 50, reduce position size — trend may be weakening
• Golden Cross = go aggressive on buys; Death Cross = switch to defensive mode
• Use EMA 200 as the final 'line in the sand' — price above = bull market

Common mistakes to avoid

• Using EMAs in isolation without confirming with volume or momentum
• Trading against the EMA 200 direction
• Not adjusting position size when EMAs are converging (uncertain trend)
