Orderbook Heatmap indicator

The screenshot shows BTC/USDT on the 4h timeframe with the Orderbook Heatmap switched on. Each colored column sits behind one candle.

1. Overview

The Orderbook Heatmap shows where large amounts of limit orders were waiting in the orderbook while each candle was forming. Instead of only seeing the price, you see the liquidity around it: walls of resting orders that can act as support or resistance, and gaps where price can move quickly.

2. Purpose of the indicator

What does it measure?

It measures the volume of resting orders at each price level, per candle. Every cell is one price band in one candle. The color shows how much volume was waiting there compared with the rest of the visible chart.

When do you use it?

• To find liquidity walls near the current price that may stop or slow a move.
• To see whether large orders stay in place, or appear and vanish as price approaches.
• To spot thin areas where price can move fast because few orders are in the way.
• To confirm levels you already found with support and resistance, or with the Liquidation Heatmap.

3. How to read the indicator

• Bright yellow and red cells are price levels with a lot of resting volume. Treat them as liquidity walls.
• Blue and green cells hold less volume. Dark or empty areas have very little.
• A horizontal streak that continues over many candles is an order that stayed in the book for a long time.
• A cell that disappears as price comes close means the order was pulled or filled. Walls that vanish at the last moment are weaker than walls that hold.
• Colors are relative. They are scaled to the large volumes in the visible part of the chart, so a bright cell means “large for this view”, not a fixed number of coins.
• History is short. The heatmap only covers the most recent period (roughly the last week), so the columns start at a certain point in the chart instead of covering all candles.

5. Tips and combinations

• Switch on Peak filter when the chart looks crowded and you only want the biggest walls.
• Resting orders can be cancelled at any time. A wall is a hint, not a guarantee, so wait for price to react before trading it.
• Combine with the Liquidation Heatmap. Liquidation clusters show where positions would be forced out, the Orderbook Heatmap shows where orders are waiting. When both point at the same level, that level deserves extra attention.
• Compare columns over time: walls that keep coming back at the same price are more meaningful than a single spike.
