The 10, 20 & 50 EMA Rule Explained

Bullish means both conditions are true: 10 EMA above 20 EMA, and price above 50 EMA.

Check the two conditions

Read the EMA 10 and EMA 20 values from the chart legend, then compare the price with EMA 50. Under this method, both conditions must pass for a bullish alignment. If both comparisons point below, the alignment is bearish; mixed or equal readings are neutral / transition. A trend definition is not a guarantee of a profitable trade.

The default chart

The Moving Average Ribbon loads three EMA lines using closing prices: green 10 EMA, cyan 20 EMA and orange 50 EMA. Its fourth line is hidden; a 200-period label may still appear in the legend but is not plotted. On the daily timeframe they cover daily candles; hourly and four-hour views use their own candle periods. Hover a completed candle to inspect its values when you want a close-based check. The newest candle is still changing until it closes.

Optional RSI

RSI can be added manually through the chart’s Indicators menu. A common length is 14. Readings above 70 are commonly described as overbought and below 30 as oversold. These are conventions, not automatic reversal triggers: a strong trend can keep RSI elevated or depressed.

EMA: a smoother view of price

An exponential moving average gives more weight to recent prices. Shorter lengths react faster; longer lengths smooth more history. Because an EMA uses past data, it can lag a sudden move and repeatedly cross another average in a choppy range.

Keep the methods separate

The EMA chart is the primary tool. TradingView’s optional Buy/Sell gauge combines additional moving averages and oscillators, so it can show Neutral while the two-condition EMA check is bullish or bearish. Do not treat the gauge as an automatic result for this rule.

Volume needs a fair comparison

Current intraday volume is incomplete. Comparing it directly with an entire prior day can mislead. This version does not calculate a volume-surge badge or a 20-day volume comparison. Review the embedded chart’s available volume settings rather than assuming a confirmation is present.

Use separate questions

An EMA smooths a price sequence, optional RSI describes one form of momentum, and the optional gauge combines several technical inputs. Similar readings are not independent proof of what price will do next.
