Comment lire un graphique crypto
  • April 16, 2026

Reading a crypto chart means understanding what the price is telling us at every moment: where it’s coming from, where it’s going, and who’s in control of the market—buyers or sellers. For a beginner, a chart can seem intimidating with its candlesticks, lines, and numbers. But in reality, it’s based on a few simple principles that you can master in less than an hour.

Step 1: Understanding Japanese Candlesticks

Each candlestick represents price movement over a given period (1 minute, 1 hour, 1 day, depending on your timeframe). A candlestick provides four pieces of information:

  • Opening Price: the price at the start of the period
  • Closing Price: the price at the end of the period
  • High: the highest price reached during the period
  • Low: the lowest price reached during the period

Reading the color

By convention:

  • Green (or white) candle: the closing price is higher than the opening price. Buyers won this period.
  • Red (or black) candle: the closing price is lower than the opening price. Sellers won this period.

The body and wicks

The colored rectangle of the candle is called “the body” and represents the difference between the open and close. The thin lines above and below are the “wicks” (or shadows), which represent the extremes reached during the period.

A large green candle with short wicks indicates dominant buying pressure. A red candle with long upper wicks means that buyers tried to push the price up but were pushed back by sellers.

Step 2: Choose the Right Timeframe

The timeframe defines the duration represented by each candle. On TradingView, you can switch from 1 minute to 1 month with a single click. Here are the most commonly used timeframes:

  • 1 min to 15 min: for scalpers trading on very short-term movements
  • 1H to 4H: for day traders and swing traders
  • 1D (daily): to see the underlying trend and take a step back
  • 1W (weekly) and 1M (monthly): for long-term investors

Golden rule: never look at just a single timeframe. Always start with the 1D to identify the general trend, then gradually zoom in to your trading timeframe. This is the essence of multi-timeframe analysis, which we detail in a dedicated article.

Step 3: Identify the trend

Before doing anything, ask yourself: which direction is the market heading?

Uptrend

The price forms higher highs and higher lows. On a chart, this looks like an upward staircase. In this scenario, focus on buying.

Downtrend

The price forms lower and lower highs and lower and lower lows. The staircase is going down. Focus on selling (or stay out of the market if you’re a beginner).

Range (sideways market)

The price fluctuates between support and resistance, with no clear direction. These are the most treacherous setups for beginners: many false breaks, many stop hunts. It’s best to wait for a clear breakout before entering.

Step 4: Identify support and resistance levels

Support is a level where the price has bounced upward several times. A resistance level is a point where the price has been pushed down multiple times. These are the “decision zones” where the market consistently reacts.

How to identify them visually

Look at the price history and search for areas where the price has “touched” a level multiple times without breaking through it. The more a level has been touched, the more significant it is.

Practical tip: switch to the 1D or 4H timeframe (levels on larger timeframes are more reliable than those on smaller ones) and draw horizontal lines at points where the price has clearly bounced or been blocked at least twice.

Support/Resistance Flip

When a support level is broken to the downside, it often becomes resistance. Conversely, a resistance level broken to the upside often becomes a new support level. This is one of the most reliable patterns in technical analysis.

Step 5: Add Moving Averages

Moving averages (MA) smooth out price fluctuations to reveal the underlying trend. The most commonly used in crypto are:

  • 21-day EMA: for short-term momentum
  • 50-day EMA: for the intermediate trend
  • 200-day EMA: for the long-term trend

These averages often act as dynamic support/resistance levels. The price “touches” the 50-day EMA and then bounces back—this is a classic buy setup in an uptrend.

When the three EMAs are stacked in ascending order (price > EMA 21 > EMA 50 > EMA 200), you are in a confirmed uptrend.

Step 6: Observe the volume

Volume represents the quantity of assets traded during each period. It is displayed at the bottom of the chart as a histogram (green and red bars).

Fundamental principle: a price movement without volume is suspicious.

  • Price rising with increasing volume = healthy movement, likely continuation
  • Price rising with decreasing volume = losing momentum, watch for a reversal
  • Break of resistance with explosive volume = confirmed breakout
  • Breakout of resistance with low volume = risk of a false breakout

Step 7: Add a momentum indicator

The RSI (Relative Strength Index) is the simplest and most useful indicator for beginners. It oscillates between 0 and 100 and measures whether the price is “expensive” or “cheap” relative to its recent history.

  • RSI > 70: overbought zone, possible correction
  • RSI < 30: oversold zone, possible rebound
  • RSI between 40 and 60: neutral zone

This is not an automatic buy or sell signal (an RSI at 70 can stay at 70 for a long time in a strong trend), but it is a good indication of the market context. To take your crypto technical analysis further, you need to combine multiple indicators.

Minimum setup to get started

On TradingView, here is the setup I recommend for all beginners:

  • Japanese candlestick chart (not line chart)
  • Timeframe: start with 4H to get familiar
  • Overlayed 21, 50, and 200 EMAs
  • Volume displayed at the bottom
  • 14-period RSI as a secondary indicator
  • Support and resistance levels drawn by hand at obvious points

Avoid displaying 10 indicators simultaneously at all costs. The more you add, the more confused you’ll become. Three indicators understood well are better than ten used poorly.

Beginner mistakes to avoid

Focusing solely on the 5-minute chart

The 5-minute chart is tempting because it moves quickly, but it generates a lot of noise and false signals. Start with the 4-hour or daily chart and learn to read the market on these timeframes first.

Trying to predict the price

A chart doesn’t tell you what’s going to happen. It shows you probabilities and areas where the market is likely to react. Learn to think in terms of probabilities, not certainties.

Ignoring the macro context

If Bitcoin has just dropped 10% in a single day, all altcoins will follow suit, regardless of what their individual charts indicate. Always check BTC’s direction before trading an altcoin.
