A candlestick chart is the most common way to read price in the crypto market, and you do not need to write a line of code to understand it. Each candle is a small, honest summary of what happened to price over one slice of time. The skill is not memorising patterns — it is reading what a candle actually says, and resisting the urge to read in what it does not.
What one candle contains
Every candle encodes four prices for its period: the open (price at the start), the close (price at the end), the high, and the low. The thick part is the body, drawn between the open and close. The thin lines above and below are the wicks (or shadows), marking the highest and lowest prices touched. If the close is above the open, it is an up candle; if below, a down candle.
Reading it, step by step
- Identify the timeframe. Confirm what one candle represents — a minute, an hour, a day — before reading anything into it. The same shape means very different things on a 1-minute and a 1-day chart.
- Read the body. A long body shows decisive movement in one direction; a small body shows indecision, where open and close ended up close together.
- Read the wicks. Long wicks mark prices that were tested and rejected within the period — buyers or sellers pushed there, then lost the ground.
- Read it in context. A single candle in isolation tells you very little. Compare it to the candles around it, and to liquidity and spread, before drawing any conclusion.
What a candle does not tell you
A candle shows what price did, never what it will do next. Patterns can describe the past cleanly and still fail to predict the future — that is normal, not a bug. A candle also says nothing about your cost to trade it: the spread you would cross and the slippage you might pay sit outside the chart entirely. Reading candles well is a literacy skill, not a crystal ball, and it pairs best with a clear-eyed view of trading costs.
