What Is Renko Chart?
Renko charts are a chart type that removes time from the equation entirely. Each brick (block) is drawn only when price moves by a specified amount (e.g., $500 for BTC). If price moves $500 up, a green brick is drawn. If it moves $500 down, a red brick. Movements less than the brick size are ignored. This filters out noise and shows only significant price moves.
How Renko Chart Works
Renko bricks are always the same height, making trends visually clean — a series of green bricks is a clear uptrend; red bricks show a clear downtrend. Trend changes are identified by a color change (a red brick after a series of green bricks). Support and resistance levels align precisely with brick boundaries, simplifying level identification.
Why It Matters for Traders
Renko charts are excellent for trend identification and for traders who struggle with the noise of candlestick charts. By removing time-based noise, Renko reveals the underlying trend structure more clearly. The trade-off is that timing precision is lost — since bricks aren't time-based, you can't determine exactly when a signal was generated. Many traders use Renko for trend identification and standard candlesticks for entry timing.
