What a timeframe is
A timeframe is the period of time that one candle or bar on a chart represents. On an hourly chart, each candle shows where price opened, the high, the low and where it closed during one hour. On a daily chart, each candle covers one trading day.
Changing the timeframe does not change the market. It only changes how price data is grouped. A daily candle and all the hourly candles inside that day describe the same price movement at different levels of detail.
If candles are new to you, read Reading charts and Candlestick Patterns first.

“M5 M15 H1 meaning”: how the labels work
MetaTrader and most charting software use short labels. The letter gives the unit, and the figure after it tells you how many of that unit each candle covers:
| Label prefix | Unit | Examples on the chart |
|---|---|---|
| M | Minutes | “M1”, “M5”, “M15”, “M30” |
| H | Hours | “H1”, “H4” |
| D | Days | “D1” |
| W | Weeks | “W1” |
| MN | Months | MN |
So “M5” means each candle covers five minutes, “M15” covers fifteen minutes, and “H1” covers one hour. The letters M and MN are easy to confuse. M is minutes and MN is months.
MetaTrader 4 has a fixed set of standard timeframes. MetaTrader 5 adds more intermediate options, such as more minute and hour steps. See MetaTrader 4 and MetaTrader 5 for how each platform works.
What each group of timeframes shows
Minute charts. These show fine detail: short bursts around news, spread widening, and quick reversals. Much of this movement is noise, meaning random back-and-forth price movement with no lasting direction.
Hour charts. These show the shape of a trading day and how price behaves across trading sessions. Swings are clearer, and single spikes matter less.
Daily, weekly and monthly charts. These show the broader direction, major highs and lows, and longer ranges. A single candle can contain a lot of intraday volatility that you cannot see at this level.
Timeframe, holding period and noise
The timeframe a trader watches usually matches how long they expect to hold a position:
- Very short holds (scalping, intraday): minute charts. Many signals appear, but many are noise. Trading costs such as the spread and commission per lot take up a larger share of each small move.
- Holds of hours to days (swing trading): hour and daily charts. Moves are larger compared with costs. Positions held past rollover pay or receive swap.
- Holds of weeks or longer: daily, weekly and monthly charts. Stop distances are wider, so position size usually has to be smaller for the same money at risk. Swap and weekend gaps matter more.
The general rule: a lower timeframe means more candles, more noise and more decisions. A higher timeframe means fewer signals, wider stops and longer exposure. To size a position for a given stop distance, use the tools on Calculators and enter your own inputs. This page gives no sample figures.
Is there a best timeframe for trading?
No single timeframe suits everyone. The right choice depends on how much time you can watch the screen, how wide a stop you can accept, and how costs compare with the moves you aim for. Lower timeframes are not "faster profit." They mean faster decisions and often faster losses.
Leveraged forex and CFD trading can lose money quickly on any timeframe. Practising on a demo account shows how a timeframe feels before real money is involved. Also read Risk management.
Precise points for experienced traders
- Candle boundaries follow server time. Each candle opens at a fixed time on the broker's server clock. Daily candles therefore depend on the server's time zone. Different brokers can show different daily highs and lows, and some show a short Sunday candle.
- Bid-based bars. MetaTrader builds bars from the bid price by default. A buy stop or limit fills on the ask, so it can trigger without the bar's high appearing to touch your level. See Bid and ask.
- MN candles are calendar months. They are not equal in length or in the number of trading days. Keep this in mind when comparing ranges.
- Volume is tick volume. In OTC forex, the volume shown is the count of price updates, not traded size. See OTC vs exchange.
- Multi-timeframe analysis. Many traders read structure on a higher timeframe and time entries on a lower one. Indicator values such as moving averages differ by timeframe because each is calculated on different bars. See Technical analysis.
- The current candle is still forming. Patterns and indicators on the latest bar can change until that bar closes.
Frequent questions
What does “M15” mean on a forex chart?
Each candle shows the open, high, low and close of fifteen minutes of trading. The M stands for minutes.
What is the difference between M and MN?
M is minutes and MN is months. MN shows one candle per calendar month.
Do lower timeframes give more accurate signals?
No. They give more signals, and a larger share of them reflect noise. Costs also weigh more on small moves.
Why does my daily candle look different on another platform?
Candles follow each server's clock. A different time zone produces different daily open, high, low and close values.
Which timeframe should a beginner use?
There is no correct answer. Pick a timeframe that matches how long you can hold and watch a trade, then practise on a demo account first.
