What are the best indicators for day trading?
The indicators most widely used for day trading are VWAP, moving averages (often the 9 and 20 EMA), RSI, MACD, ATR, Bollinger Bands and volume. There is no single best indicator. The most useful setup is usually two or three tools that each answer a different question: what is the trend, how strong is the move, and how far could price reasonably travel.
This guide explains what each indicator does on intraday charts, the default settings most platforms use, how to combine them without clutter, and a worked example of using ATR to size a trade.
Pick indicators by the job they do
Most indicators fall into a few groups. Using two from the same group usually tells you the same thing twice.
| Job | Indicators | Question it answers |
|---|---|---|
| Trend and fair value | VWAP, EMAs | Which side should I favor? |
| Momentum | RSI, MACD, Stochastic | Is the move strengthening or fading? |
| Volatility | ATR, Bollinger Bands | How far does price normally move? |
| Participation | Volume, OBV | Is there real interest behind the move? |
1. VWAP (volume-weighted average price)
VWAP is the average price traded during the session, weighted by volume, and it usually resets at the start of each day. Many intraday traders treat price above VWAP as a sign buyers are in control and price below it as a sign sellers are. It also acts as a magnet and a reference for pullback entries. Because institutions often benchmark execution against it, VWAP is one of the most watched intraday levels. Our VWAP guide covers anchored VWAP and bands.
2. Moving averages (EMA)
Exponential moving averages weight recent prices more heavily, so they react faster than simple averages. Day traders commonly use a 9 EMA and 20 EMA on 1-minute to 5-minute charts. When the faster average is above the slower one and both slope upward, the short-term trend is up. Pullbacks to the 20 EMA in a trend are a popular entry area. Read more in our SMA and EMA guide.
3. RSI (Relative Strength Index)
RSI measures the speed of recent gains against recent losses on a scale of 0 to 100, with a default setting of 14 periods. Readings above 70 are labeled overbought and below 30 oversold. In strong intraday trends, RSI can stay overbought or oversold for a long time, so many day traders use it for divergence or to confirm momentum rather than to fade moves. See our RSI indicator guide.
4. MACD
MACD subtracts a 26-period EMA from a 12-period EMA and plots a 9-period signal line of that difference. Crosses of the MACD and signal line, and the histogram growing or shrinking, show changes in momentum. It lags more than RSI, which can help filter noise but means later signals on fast charts. Details are in our MACD guide.
5. ATR (Average True Range)
ATR measures the average range of each bar, including gaps, over a period that defaults to 14. It does not show direction. It tells you how much a market typically moves, which makes it one of the most practical tools for setting stops and targets that fit current conditions. Our ATR guide explains the calculation.
6. Bollinger Bands
Bollinger Bands plot a 20-period simple moving average with bands two standard deviations above and below it. Narrow bands show quiet conditions that often come before a larger move, and wide bands show high volatility. In ranges, traders look for reversals near the outer bands. In trends, price can ride one band for a long time. See our Bollinger Bands guide.
7. Volume and OBV
Raw volume bars show where participation spikes, such as at the open or on news. Breakouts on rising volume tend to be more trustworthy than breakouts on thin volume. On-balance volume turns that into a running line you can compare with price, and is most useful for spotting divergence between volume and price.
Worked example: sizing a trade with ATR
You are trading the Micro E-mini Nasdaq-100 (MNQ), worth $2 per index point. On the 5-minute chart, the 14-period ATR is 8 points. You want a stop wide enough to survive normal noise, so you set it at 1.5 x ATR:
- Stop distance: 1.5 x 8 = 12 points
- Risk per contract: 12 points x $2 = $24
- Maximum risk for the trade: $100
- Contracts: $100 / $24 = 4.17, rounded down to 4 contracts
- Actual risk: 4 x $24 = $96
If you aim for a target of twice the stop distance, 24 points, the potential gain is 4 x 24 x $2 = $192 before costs. When volatility rises and ATR grows, the stop widens and the number of contracts falls, so your dollar risk stays steady. The position size calculator does this for any market.
Example combinations
- Trend pullback: VWAP for bias, 9 and 20 EMA for structure, ATR for stops.
- Range reversal: Bollinger Bands for extremes, RSI for momentum divergence, volume to confirm exhaustion.
- Open breakout: the opening range high and low, VWAP for direction, volume to confirm. Our opening range breakout strategy walks through this setup.
Mistakes to avoid
- Stacking similar indicators. RSI, Stochastic and MACD on one chart mostly repeat each other.
- Changing settings after every loss. Constant tweaking fits past data and rarely helps going forward.
- Ignoring price. Indicators are calculated from price and volume. Key levels and market structure still come first.
- Trading every signal. Indicators produce many signals in choppy sessions. Define in advance which conditions you will trade and test them on past data.
Day trading involves substantial risk of loss, and most indicators lag price and can give false signals. No indicator or combination guarantees profits. This guide is educational and is not financial advice. Read our full risk disclaimer.
