Best Indicators for Intraday Trading, and How to Combine Them
The best indicators for intraday trading are VWAP, short exponential moving averages (EMA 9 and 20), RSI, MACD, Bollinger Bands, Supertrend and ATR. No single one is "best". Intraday traders get the most from combining one indicator for trend, one for momentum and one for volatility, then testing that combination on past data before trading it.

The four jobs an indicator can do
Most beginners stack RSI, Stochastic and CCI on one chart and feel more confident. All three measure momentum, so they agree with each other and add nothing. Pick by job instead:
| Job | Question it answers | Indicators |
|---|---|---|
| Trend | Which way is the day going? | VWAP, EMA 9/20, Supertrend |
| Momentum | Is the move speeding up or running out? | RSI, MACD |
| Volatility | How far does the price normally move? Where should my stop go? | ATR, Bollinger Bands |
| Volume | Is there real participation behind the move? | Volume, VWAP |
A workable intraday setup usually has one trend filter, one entry trigger and one volatility-based stop.
1. VWAP (Volume Weighted Average Price)
What it is: the average price traded so far today, weighted by volume. It resets every morning at the open.
How intraday traders use it:
- Bias: price above VWAP means buyers have been in control on average today; below means sellers.
- Pullback entries: in a trending day, a pullback to VWAP that holds is a common entry point.
- Benchmark: large buyers and sellers often measure their own fills against VWAP, which is why price tends to react around it.
Watch out: VWAP needs volume, so it does not exist for an index itself. Read it on NIFTY futures, an option or a stock, not on the NIFTY 50 spot.

2. Moving averages (EMA 9 and 20)
What it is: the average closing price over the last N candles. An EMA (exponential moving average) gives more weight to recent candles, so it reacts faster than a simple moving average (SMA). That makes EMAs the usual choice on intraday charts.
How intraday traders use it:
- Direction: a rising EMA 20 on a 5-minute chart describes an up-trending session.
- Crossovers: EMA 9 crossing above EMA 20 is a classic bullish trigger; crossing below is bearish.
- Dynamic support: in a strong trend, price often pulls back to the EMA 20 and bounces.
Watch out: in a sideways market, the two EMAs cross back and forth and generate a string of small losing trades. Pair crossovers with a trend filter such as VWAP.

3. RSI (Relative Strength Index)
What it is: a momentum oscillator from 0 to 100 that compares recent up-moves with recent down-moves. The default period is 14.
How intraday traders use it:
- Overbought and oversold: above 70 is stretched to the upside, below 30 to the downside.
- Trend filter: in an uptrend, RSI tends to hold above 40–50 on pullbacks. "Buy pullbacks while RSI stays above 40" often works better intraday than "buy when RSI is below 30".
- Divergence: price makes a new high but RSI makes a lower high, a warning that the move is losing strength.
Watch out: in a strong trend, RSI can stay above 70 for hours. Selling just because it is "overbought" is one of the most common intraday mistakes.

4. MACD (Moving Average Convergence Divergence)
What it is: the difference between a 12-period and a 26-period EMA (the MACD line), a 9-period EMA of that line (the signal line), and the gap between them (the histogram).
How intraday traders use it:
- Signal-line crossover: MACD crossing above its signal line is bullish; below is bearish.
- Zero line: MACD above zero means the short-term average is above the longer one: an upward bias.
- Histogram: shrinking bars show momentum fading before price turns.
Watch out: MACD is built from moving averages, so it lags. On a 5-minute chart the signal often comes after a good part of the move is over.

5. Bollinger Bands
What it is: a 20-period SMA with bands two standard deviations above and below it. The bands widen when the market is volatile and narrow when it is quiet.
How intraday traders use it:
- Squeeze: very narrow bands mean low volatility, which is often followed by a bigger move. Traders wait for a close outside the band to pick the direction.
- Mean reversion: on a range-bound day, a touch of the outer band followed by a close back inside can signal a move back to the middle.
- Riding the band: in a strong trend, price "walks" along the upper or lower band.
Watch out: the same touch of the upper band can mean "overbought" on a sideways day and "strong trend" on a trending one. Decide which kind of day you are trading before you use it.

6. Supertrend
What it is: a trend-following line built from ATR. Common settings are period 10 and multiplier 3 (some intraday traders use 7 and 3 for faster signals). The line sits below price in an uptrend and above it in a downtrend.
How intraday traders use it: as a trend filter (only buy when price is above Supertrend) and as a trailing stop (exit when a candle closes on the other side of the line).
Watch out: like every trend follower, it whipsaws in a range.
7. ATR (Average True Range)
What it is: the average size of a candle's range, including gaps, over the last N candles (usually 14). It does not tell you direction, only how much the price normally moves.
Why it may be the most useful intraday indicator: it tells you where to put your stop and how big your position should be. A fixed 20-point stop is tight on a volatile day and loose on a quiet one. A stop at 1.5 × ATR adapts.
How to combine intraday indicators
A combination works when each indicator answers a different question. Three examples:
| Setup | Trend filter | Entry trigger | Stop and exit |
|---|---|---|---|
| Trend pullback | Price above VWAP | EMA 9 crosses above EMA 20 on a closed 5-min candle | 1.5 × ATR below entry; exit all by 3:15 pm |
| Momentum breakout | Supertrend (10, 3) is bullish | Close above the first 15 minutes' high | Below the opening-range low; trail with Supertrend |
| Range fade | Narrow Bollinger Bands, flat EMA 20 | Close back inside the lower band with RSI below 30 | Middle band as target; fixed stop below the day's low |
Common mistakes with intraday indicators
- Too many indicators. Five momentum indicators agreeing is still one opinion.
- Optimising settings to the past. If RSI 11 with 73/27 levels works but 14 with 70/30 doesn't, you have probably fitted noise.
- Ignoring the first and last minutes. The opening minutes are noisy; many intraday systems skip the first 15 minutes and exit before the close.
- No time exit. An intraday trade needs a cut-off, for example 3:15 pm, or your broker squares it off for you.
- Trading the same rules on every kind of day. Trend tools fail on range days and range tools fail on trend days. A filter that tells them apart is part of the strategy.
Turning indicator rules into an automated strategy
Indicator rules are precise, which makes them easy to automate. That also removes the hardest part of intraday trading: acting on the signal exactly when it comes, and taking the stop when it is hit.

Frequently asked questions
Which is the best indicator for intraday trading?
There is no single best indicator. VWAP is the most widely watched intraday reference, EMAs and Supertrend show trend, RSI and MACD show momentum, and ATR sizes stops. Most traders combine one trend indicator, one trigger and an ATR-based stop.
What are the best indicator settings for intraday trading?
Common starting points are EMA 9 and 20, RSI 14, MACD 12/26/9, Bollinger Bands 20 and 2, Supertrend 10 and 3, and ATR 14, on 5- or 15-minute candles. Keep the defaults unless a backtest shows a clear, stable reason to change them.
Which timeframe is best for intraday indicators?
The 5-minute and 15-minute charts are the most common. One-minute charts give more signals but more noise. Many traders read the trend on 15 minutes and time entries on 5 minutes.
Is VWAP better than a moving average for intraday trading?
They do different jobs. VWAP resets every day and includes volume, so it shows where today's average buyer and seller stand. A moving average follows recent closes across days. Many traders use VWAP for bias and EMAs for entries.
Can I use RSI alone for intraday trading?
It is risky. RSI can stay overbought or oversold for long periods in a trend, so a reversal signal on its own often fails. Use it with a trend filter and always with a stop loss.
Can I automate intraday indicator strategies?
Yes. On Tradetron, indicators such as EMA, VWAP, RSI, MACD, Bollinger Bands, Supertrend and ATR are available as keywords in a no-code builder. You can backtest the rules, run them Live Offline, then connect a broker.
