Every candlestick chart is built from bars, and each bar covers a fixed slice of time. On a daily chart each candle is one trading day from 09:15 to 15:30. On a 15-minute chart each candle is fifteen minutes, so one NSE session makes 25 candles. On a weekly chart each candle is a whole week. This slice of time is the chart's timeframe, and choosing it is one of the first decisions a trader makes, often without realising it.
The timeframe changes everything you see: the trend, the support levels, the indicator readings and the signals. A stock can be in a clear uptrend on the weekly chart, a pullback on the daily chart and a sharp rally on the 5-minute chart, all at once. None of these is wrong. They are answers to different questions.
Match the timeframe to your holding period
The simplest rule: the chart you trade from should show roughly 20 to 100 bars over the time you expect to hold a trade.
| Style | Typical holding time | Common trading chart | Common higher chart |
|---|---|---|---|
| Scalping | Minutes | 1-minute | 5-minute |
| Intraday | Within the day (out by 15:30) | 5 or 15-minute | 60-minute or daily |
| Swing | A few days to a few weeks | Daily | Weekly |
| Positional / investing | Months or longer | Weekly | Monthly |
A swing trader using a 1-minute chart sees hundreds of meaningless wiggles and gets shaken out of good trades. An intraday trader using a weekly chart cannot see anything that happens today.
Why indicators change with the timeframe
A "14-period RSI" on a daily chart looks at 14 days. On a 15-minute chart it looks at 14 fifteen-minute bars: about half a session. They are completely different readings. The same is true for moving averages: the 200-day average reflects most of a year, while a 200-bar average on a 5-minute chart covers about 2.7 sessions.
The indicator box below shows daily readings for Infosys: RSI, MACD, the 50 and 200-day averages and Supertrend, all calculated on daily candles.
Treat these as the daily picture. If you trade Infosys intraday, the 15-minute RSI may be far from this number. A common habit is to note the daily direction from this kind of summary (price above or below the 50 and 200-day averages) and only take intraday trades that agree with it.
Using more than one timeframe
Many traders look at two or three timeframes, each about 4 to 6 times longer than the last. A popular version of this is Alexander Elder's "triple screen" approach:
- Higher timeframe for direction. A swing trader checks the weekly chart: is the stock above a rising 30-week average? Then only look for buys.
- Trading timeframe for setup. On the daily chart, wait for a pullback: RSI or the stochastic dips, the price nears support or a Fibonacci level.
- Lower timeframe for timing. On a 60-minute chart, enter when the pullback ends, for example on a break above the previous hour's high.
For an intraday NIFTY trader the same idea might be daily, 15-minute and 3-minute charts, with VWAP on the intraday charts to show who is in control since 09:15.
A worked example
Suppose a stock at ₹2,450 is above its rising 30-week and 200-day averages: the weekly and daily trends are up. Over five days it slips to ₹2,360, near its 50-day average, and the daily RSI drops from 65 to 45. On the 60-minute chart it forms a higher low at ₹2,365 and breaks above the prior hour's high of ₹2,385. A trader using three timeframes might buy at ₹2,386 with a stop below ₹2,360. The weekly chart gave the direction, the daily chart the setup, the hourly chart the moment. Each layer filters out trades the others would have allowed.
Daily candles, weekly candles and the trading session
A few details are worth knowing about how candles are built. A daily candle on NSE runs from the 09:15 open to the 15:30 close; the pre-open session before 09:15 sets the opening price but is not a separate candle on most charts. A weekly candle opens on the first trading day of the week and closes on the last, so a holiday week has fewer days inside it. MCX commodities trade until late in the evening (up to 23:30 or 23:55 depending on the season), so an MCX daily candle covers far more hours than an NSE one, and intraday charts for gold or crude oil show a long evening session that stock charts do not have.
Intraday candles are usually aligned to the session start: on a 15-minute chart the first candle covers 09:15 to 09:30, the second 09:30 to 09:45, and so on. On a 60-minute chart the last candle of the day is shorter (14:15 to 15:30 is 75 minutes on some charts, or the final bar is cut at 15:30 on others), which can make the last bar look unusual. These details matter when you compare the same indicator across different chart sites and get slightly different numbers.
Noise, costs and the number of signals
Shorter timeframes produce more signals, which feels like more opportunity. But each move is smaller, so brokerage, taxes and slippage take a bigger share of each trade. A 0.3% target on a 5-minute chart can be half eaten by costs; a 6% target on a daily chart barely notices them. Shorter charts also react more to random order flow, especially in the first fifteen minutes after 09:15 and near the close. Beginners usually find daily charts easier to learn on: fewer decisions, more time to think, and the chance to plan trades in the evening rather than react during market hours.
Timeframes in backtesting
When you test a rule, the timeframe is part of the rule. A moving-average crossover that works on daily bars may fail on 5-minute bars, and vice versa. The ScreenerCharts backtester lets you run the same entry and exit rules on 5, 15 and 60-minute or daily bars for indices and F&O stocks, so you can compare them directly. The backtesting guide explains how to read the results.
Common mistakes
- Switching timeframes mid-trade. Entering on a 5-minute signal, then holding a loser because "the daily chart looks fine".
- Looking at too many charts. Five timeframes will always disagree somewhere. Two or three is enough.
- Using daily stops on intraday trades. Stops and targets should come from the chart you trade.
- Ignoring the session. Intraday indicators reset meaning overnight; a 15-minute chart's first bar after a gap is not comparable with the bars before it.
- Thinking a shorter timeframe is more accurate. It is more detailed, not more predictive.
