Reading charts: candles, timeframes and keeping them clean

How a Japanese candlestick is built, what it really tells you, how to choose a timeframe and how to set up a readable chart.

The chart is your daily working tool. If you can't read it, every later concept (trend, support, patterns, indicators) becomes a meaningless drawing. In this lesson you learn the alphabet: how a candle is built, what it tells you, how to change perspective with timeframes and how to set up a clean chart, which is the first difference between an orderly trader and a confused one.

Three ways of showing price

  • Line chart: connects the closes. Clean, but loses a lot of information.
  • Bar chart (OHLC): for each period shows open, high, low and close.
  • Japanese candlestick chart: the same information as bars, but easier to read at a glance. It's the standard for almost all traders, and the one we'll use.

Anatomy of a candle

Each candle summarises what happened to price over a time interval (a minute, an hour, a day...). It has four data points, called OHLC:

  • Open: the opening price
  • High: the highest price reached
  • Low: the lowest price reached
  • Close: the closing price

The body is the wide part: it goes from open to close. The wicks (or shadows) are the thin lines reaching the highs and lows. The colour shows direction:

TypeBodyMeaning
Bullish candleCloses above the open (usually green or white)Buyers prevailed during the period
Bearish candleCloses below the open (usually red or black)Sellers prevailed during the period

What a candle really tells you

Candles aren't "trading cards" to collect: they're the story of a battle between buyers and sellers. Learn to read it:

  • Long body: one side dominated decisively. A long bullish candle with no wicks says "buyers controlled the whole period".
  • Short body: indecision, balance.
  • Long upper wick: price rose but was rejected: sellers stepped in. It can signal rejection of high prices.
  • Long lower wick: price fell but was rejected: buyers stepped in.
  • Long wicks on both sides: big volatility and indecision.

The timeframe: your magnifying glass

The timeframe is the duration of each candle. Each timeframe tells a different scale of the same story:

TimeframeTypical use
M1, M5, M15Very fast trading (scalping). A lot of noise, many costs
M30, H1, H4Intraday and short swings. A good balance to start
D1 (daily)Context, main trend, key levels
W1, MNLong-term view

A typical mistake is staying glued to a low timeframe. On the one-minute chart every wiggle looks like an event, but it's often noise: random moves of little consequence. A clear trend on the daily can look like chaos on the minute, and vice versa. That's why we use the top-down approach: first the high timeframe to understand context, then the low one to choose the entry.

Volume in forex

In stocks, volume is the number of shares traded. In forex, being a decentralised market, there is no official volume. Platforms show the tick volume: the number of price changes in the period. It's an approximation, useful to understand when there's activity, not for precise assessments.

How to set up a clean chart

A chart full of indicators, lines, arrows and colours is unreadable. Follow these principles:

  1. Neutral background and sober colours (green/red or blue/red), no intrusive grids.
  2. Few elements: candles, a few levels, at most two or three indicators.
  3. Enough history: look back far enough to see the important levels.
  4. A saved template: once set up, reuse it on every pair to stay consistent.
  5. No notifications or needless windows while you concentrate on analysis.

Try it yourself on a real chart

Below is a real, interactive EUR/USD 1-hour chart. Scroll back by dragging, zoom with the wheel and read the candles one by one: where is a long body? Where do you see rejection wicks? You can change timeframe from the top menu and change pair by clicking the symbol.

Common mistakes

  • Being hypnotised by the movement of the latest candle on low timeframes.
  • Confusing colour with a guarantee of future direction: a bullish candle doesn't predict the next.
  • Analysing a chart "in hindsight" thinking "it was obvious". To the right of the chart there is always the future, which you can't see.
  • Filling the chart with indicators to feel safer.

In short

  • A candle summarises open, high, low and close of a period.
  • Body and wicks tell the balance of power between buyers and sellers.
  • The timeframe changes the scale: use top-down (high for context, low for entry).
  • In forex the volume shown is tick volume, indicative only.
  • Keep the chart clean: few elements, consistent.

Practical exercise

  1. Open EUR/USD on H1 and scroll through the last 20 candles: for each, write in one word what it "said" (buyers dominating, rejection, indecision...).
  2. Switch to D1 and repeat on 20 daily candles. What changes in the story?
  3. Set up a clean template and save it.
