Limit Order (Bid/Ask) Heatmap

See where unfilled limit buy and sell orders are sitting on the order book using Hyperliquid on-chain data.

What is Limit Order Heatmap?

Limit Order Heatmap displays pending (unfilled) limit orders from the Hyperliquid order book as a visual overlay on your chart. All data is sourced directly from Hyperliquid’s on-chain order book.

The heatmap uses a viridis color scale by default — intensity progresses from dark purple (low volume) through teal and green to bright yellow (high volume). Bid orders (limit buys) are shown in green tones and ask orders (limit sells) in red tones, making it easy to see where buying and selling interest is stacked. You can switch between five color themes — Viridis (default), Heat, Ocean, Monochrome, and Classic — in the overlay settings.

Unlike traditional exchange order books that can be spoofed with orders that disappear before execution, on-chain orders on Hyperliquid carry more weight because they are committed to the blockchain. This gives you a more reliable view of where real buying and selling interest is positioned.

Key Concepts

• Bid Orders (Green): Pending limit buy orders — these represent demand waiting below the current price and form potential support levels. Rendered in green tones by default.
• Ask Orders (Red): Pending limit sell orders — these represent supply waiting above the current price and form potential resistance levels. Rendered in red tones by default.
• Color Intensity: Brighter bars indicate higher order volume at that level. In viridis mode, intensity progresses from dark purple (low) → teal → green → yellow (high).
• Order Depth: The aggregate size of limit orders at each price level — thicker bars mean larger resting orders
• On-Chain Order Book: Orders placed on Hyperliquid’s L1 chain, giving full transparency into pending order placement
• Color Themes: Choose from Viridis (default), Heat, Ocean, Monochrome, or Classic — each provides a different visual mapping of order density

How to Use Limit Order Heatmap

1. Open Chart from the sidebar and navigate to the overlay settings
2. Enable the Limit Order Heatmap overlay
3. Green-toned bars below price show where bid (buy) orders are concentrated
4. Red-toned bars above price show where ask (sell) orders are concentrated
5. Brighter, more intense bars indicate larger order volume at that level
6. Monitor how these clusters shift as price approaches them
7. Optionally switch the color theme in overlay settings (Viridis, Heat, Ocean, Monochrome, Classic)

What to Look For

• Bullish signals: A thick wall of bid orders stacking at a specific price level below the market suggests strong buying interest and a likely support zone. If bids hold firm as price approaches, buyers are committed to defending that level.
• Bearish signals: Heavy ask order concentration above the current price creates a resistance ceiling. When price rallies into a dense ask wall and stalls, the supply is absorbing buying pressure and may cause a rejection.
• Key patterns: Watch for orders being pulled (thinning out) as price approaches — this “order book fading” often signals that the level will not hold. Conversely, orders building as price approaches indicate conviction behind the level. Large isolated limit orders (icebergs) at specific prices are often institutional and carry significant weight.

Tips

• Limit orders represent intention — they are not guaranteed to execute. Always confirm with actual trade data from Trade Footprint when price reaches a cluster
• Large bid walls below a range low often signal accumulation — smart money placing bids where retail is panicking
• The heatmap updates in real time as orders are placed, modified, and cancelled, so treat it as a dynamic map rather than a static snapshot
• Try the Heat or Ocean color themes if you find viridis hard to read on your monitor
