A crypto liquidation heatmap is one of the most useful tools a derivatives trader can have open alongside their charts, yet it gets far less attention than indicators like RSI or moving averages. The heatmap shows where large clusters of leveraged positions will be forcibly closed if price reaches a given level. When those clusters are big enough, they act as magnets: market makers and large players actively push price toward them to collect the liquidity sitting there.
For Australian traders watching BTC, ETH, or SOL on exchanges like Bybit or Binance, learning to read this data can be the difference between entering a trade with context and entering into a trap.
What a liquidation heatmap actually shows
Every leveraged position has a liquidation price. That's the level at which the exchange forcibly closes the trade and the collateral is taken. A heatmap aggregates millions of open positions across major exchanges and plots their liquidation prices on a vertical axis, with time along the horizontal axis.
The colour intensity tells you how much capital is sitting at each price level. Bright yellow or white zones on most heatmaps represent the heaviest concentrations, often hundreds of millions of dollars in open positions that would get swept if price moves through that level. Cooler colours, blues and greens, indicate thinner clusters that the market can pass through with less drama.
There are two sides to every heatmap. Long liquidations sit below the current price: those are traders betting on price rising who will be wiped out if price falls to their level. Short liquidations sit above: traders betting on a decline who get closed out if price rallies. Heatmaps usually display both simultaneously, giving you a picture of where gravity might pull price in either direction.
Where to find liquidation heatmap data
The most widely used tool is Coinglass, which aggregates liquidation data from Binance, Bybit, OKX, and other major perpetual futures exchanges. The heatmap on Coinglass updates in near-real time and lets you toggle between BTC, ETH, SOL, and a handful of other assets. Note that it covers centralised derivatives exchanges only. It doesn't capture decentralised perpetuals protocols like GMX or dYdX, so it's a picture of the market, not the whole market.
Other platforms including Hyblock Capital offer more granular heatmap overlays with additional filters, though some of those features sit behind a subscription. For most retail traders in Australia, the free Coinglass heatmap is a solid starting point.
How to read the levels in practice
The practical reading method has three steps. First, identify the brightest cluster closest to the current price. That's the level most likely to be targeted in the next significant move. Second, check whether the cluster sits above or below price, because that tells you the direction of the likely sweep. Third, check the timeframe: a cluster that's been building for 48 hours is stickier than one that appeared in the last few hours, because more traders have had time to add to positions at that level.
Consider a concrete example. If BTC is trading at AU$165,000 and there's a dense yellow zone at AU$160,000 (long liquidations) and a lighter cluster at AU$172,000 (short liquidations), the heatmap is telling you that a downside sweep is more explosive than an upside one. A drop to AU$160,000 would cascade through a wall of long liquidations, accelerating the move. A rally to AU$172,000 would close fewer positions and generate less forced buying.
This is why experienced traders often place entries just after a liquidation sweep rather than before one. Price tends to spike sharply through a liquidation cluster and then reverse. The reversal happens because the forced selling (or buying) exhausts itself quickly once those positions are closed.
Liquidation heatmaps versus open interest
It's worth separating what a heatmap shows from what open interest shows, because traders sometimes conflate the two. Open interest is the total value of all outstanding derivatives contracts. The heatmap is a distribution of where specific price levels will force those contracts to close. They're related but different questions. High open interest with a dense liquidation cluster nearby is a more powerful signal than either figure alone.
If you're already using open interest alongside volume to gauge market conviction, adding the liquidation heatmap gives you the spatial component: not just how much leverage is in the market, but exactly where it breaks.
Common mistakes when using heatmaps
The biggest mistake is treating heatmap clusters as guaranteed price targets. They're not. They're zones of elevated probability. Price sometimes approaches a cluster and reverses before sweeping it, particularly in low-volatility conditions. The heatmap shows you the map; it doesn't guarantee the route.
A second mistake is ignoring the macro trend. A downside liquidation cluster in a strong bull trend may never get swept because sustained buying pressure keeps price elevated. Context matters. The heatmap is a supplement to trend analysis and on-chain data, not a replacement.
Third, don't treat a sweep as a buy or sell signal in isolation. A sweep followed by a fast close back through the level (a wick on the candle, essentially) is a much stronger reversal signal than a slow grind through the same zone. Speed and volume at the moment of the sweep tell you whether the market has actually exhausted those positions or is continuing through them.
Understanding on-chain funding rates alongside the heatmap adds another layer: when funding is deeply negative and a major long liquidation cluster sits below price, the conditions for a sharp but brief flush are set up clearly.
ATO and tax considerations for derivatives traders
If you're trading perpetual futures on a platform accessible from Australia, the ATO treats your gains and losses as assessable income under ordinary income rules, not as CGT events. That's a meaningful distinction. Profits are taxed at your marginal rate, and losses can offset other income in the same financial year. The exchanges generating the liquidation data you're reading (Bybit, Binance) are not AUSTRAC-registered, which means Australian traders using them carry additional regulatory and counterparty risk. That doesn't make the data less useful, but it's context worth holding when deciding where to actually execute trades.
Keeping accurate records of every derivatives trade, including liquidations (which are effectively forced closures at a loss), is essential for ATO compliance. If you're tracking these through a portfolio tool, make sure it supports futures and perpetuals, not just spot trades.
Putting it together
A liquidation heatmap won't tell you where price is going. What it tells you is where the market has concentrated leverage, and by extension, where a move of sufficient size will accelerate on its own. That's genuinely useful information for timing entries, placing stops outside sweep zones, and understanding why price sometimes spikes sharply to a level and reverses without any obvious news catalyst.
Use it alongside your standard technical tools, keep an eye on funding rates, and treat the brightest clusters as areas of elevated risk rather than guaranteed stops. That framing keeps the heatmap in its proper role: one input among several, not a trading strategy on its own.
