What is a Moving Average Crossover?
A moving average crossover occurs when a faster EMA crosses above or below a slower EMA — indicating a potential trend change.
Golden Cross: EMA 50 crosses above EMA 200 — strong long-term bullish signal, often precedes major rallies.
Death Cross: EMA 50 crosses below EMA 200 — strong long-term bearish signal, often precedes prolonged downtrends.
Bullish Crossover: EMA 20 crosses above EMA 50 — short-term uptrend signal.
Bearish Crossover: EMA 20 crosses below EMA 50 — short-term downtrend signal.
Types of Moving Averages
There are two main types of moving averages used in this screener:
Simple Moving Average (SMA / DMA): Calculated by summing closing prices over N periods and dividing by N. Equal weight to all periods. Formula: SMA = Sum(prices) / N
Exponential Moving Average (EMA): Gives more weight to recent prices. Reacts faster to price changes than SMA. Formula: EMA = (Price × Multiplier) + EMA(previous) × (1 − Multiplier)
Key Moving Average Levels to Watch
200 DMA: The most important long-term trend indicator. Stocks above 200 DMA are in a long-term uptrend. Stocks breaking above the 200 DMA after a sustained period below it are prime swing trade candidates.
100 DMA: Medium-term trend indicator — useful for swing trades of 1–3 months.
50 DMA: Medium-short term — popular for identifying trend health in ongoing uptrends.
20 EMA: Short-term trend — widely used by intraday and positional traders for entries and stops.
How crossovers are detected
This screener computes EMA values on 1 year of daily candles. Crossovers are detected by comparing the current EMA relationship with values from 10 days ago (short-term) or 20 days ago (long-term). If the fast EMA was below the slow EMA 10 days ago but is above it now, a Bullish Crossover is flagged.
Understanding MA Crossover Signals
MA above stock price → stock rises above MA: Traders read this as a bullish signal — the stock has regained short-term momentum.
MA below stock price → MA rises (stock falls): Traders read this as a bearish signal — the downward momentum is dragging the MA up.
Stocks breaking out of 200 DMA: These are prime intraday and swing trade candidates in the coming sessions.
