The best indicators for swing trading are the simple ones that answer different questions: moving averages for trend, RSI for momentum, volume for conviction, ATR for volatility and stop placement, and relative strength for picking the strongest stocks. Use one from each group, not five that measure the same thing. Price and key levels still come first; indicators add context.
Group indicators by the question they answer
| Question | Indicator | Common swing settings |
|---|---|---|
| What’s the trend? | Moving averages (EMA or SMA) | 20, 50 and 200 days |
| Is momentum strong or fading? | RSI | 14 periods |
| Is momentum turning? | MACD | 12, 26, 9 |
| Is there conviction? | Volume, volume average | 50-day average volume |
| How much does it move? | ATR | 14 periods |
| Is it beating the market? | Relative strength vs an index or sector, RRG | 10–14 weeks |
Two indicators answering the same question (RSI and Stochastics, say) mostly repeat each other.
Moving averages: the trend
- 20-day EMA: the short-term trend. Strong stocks often pull back to it.
- 50-day: the medium-term trend and a common pullback level.
- 200-day: the long-term line. Many swing traders only buy stocks above it.
How to use them: trade in the direction of the slope. When the 20 is above the 50 and both are rising, look for long setups on pullbacks.
RSI: momentum
RSI measures recent gains against losses on a 0–100 scale.
- Above 50 generally means bullish momentum, below 50 bearish.
- In strong uptrends, RSI often stays between 40 and 80. A dip to around 40–50 can mark a pullback entry.
- 70 and 30 are the classic overbought and oversold lines, but in trends they’re not sell or buy signals by themselves.
- Divergence, where price makes a new high but RSI doesn’t, warns that momentum is fading.
MACD: momentum turning
MACD compares two moving averages. Swing traders watch the MACD line crossing its signal line and the histogram shrinking or growing. It’s slower than RSI, which helps filter noise but means later signals.
Volume: conviction
- Breakouts on volume well above average are more reliable.
- Pullbacks on light volume suggest sellers aren’t in control.
- A volume surge after a long run can mean exhaustion.
ATR: stops and position size
Average True Range measures how much a stock typically moves per day. It’s not a direction signal, but it’s one of the most useful swing tools:
- Stops: place stops beyond normal noise, for example 1.5–2 ATR below entry or below a swing low.
- Position size: a stock with a large ATR needs a smaller position for the same dollar risk. See the position size calculator.
Relative strength: picking winners
Swing traders make most of their money in stocks that beat the market. Relative strength compares a stock to an index or its sector. A relative rotation graph shows relative strength and its momentum for a whole group at once. See RRG vs a relative strength line.
A simple combination that works for many traders
- Filter: price above a rising 50-day; stock or sector leading on relative strength.
- Setup: pullback to the 20-day EMA or a prior breakout level, with RSI dipping to about 40–50.
- Trigger: a bullish candle off the level with volume picking up.
- Stop: below the pullback low or about 1.5–2 ATR.
- Target: prior high, or 2R or more.
Test any combination before trading it. Our guide on how to backtest a trading strategy shows how to do it without fooling yourself.
Mistakes to avoid
- Indicator stacking: five oscillators saying the same thing.
- Ignoring price: indicators lag price.
- Changing settings after every loss.
- Buying “oversold” stocks in downtrends.

Frequently asked questions
What is the best indicator for swing trading?
There’s no single best one. Many swing traders combine a moving average for trend, RSI for momentum, volume for conviction and ATR for stops.
What RSI setting is best for swing trading?
The default 14-period RSI on daily charts is the most common. In uptrends, dips to about 40–50 often mark pullbacks.
How many indicators should I use?
Two to four, each answering a different question. More usually adds noise.
