How to Read a Liquidation Heatmap
Liquidation heatmaps show where leveraged positions are likely to be force-closed. Learn how the map is built, what the bright zones mean, and how traders use them.
If you have ever watched Bitcoin drift toward a round number, spike straight through it, then instantly reverse, you have watched a liquidation event. Price is drawn toward areas where leveraged positions must be force-closed, because forced orders are guaranteed fuel. A liquidation heatmap makes those areas visible before price gets there.
First, what a liquidation is
When a trader opens a leveraged position on a perpetual futures exchange, they post margin. If price moves against the position far enough that margin can no longer cover the loss, the exchange force-closes it, buying back a short or selling out a long, at market. That forced market order is a liquidation.
The key insight: a liquidated long becomes a forced sell order and a liquidated short becomes a forced buy order. Liquidations do not just mark the end of someone's trade, they inject aggressive volume into the market at a predictable price. Enough of them close together and you get a cascade: liquidations push price into the next band of liquidations, which push it further, until the pocket is cleared.
How the heatmap is built
Exchanges do not publish where everyone's liquidation price sits, so a heatmap is an estimate. The general method: take where positions were opened (from price and open interest changes), apply common leverage levels such as 10x, 25x, 50x and 100x, and compute where each cohort of positions would be liquidated. Aggregate that across time and you get a density map of likely liquidation levels above and below the current price.
The result is drawn as a heatmap over the price chart: the x-axis is time, the y-axis is price, and color intensity shows how much estimated liquidation volume rests at each level. Bright bands are dense clusters. Dim areas are relatively empty.
Reading the map
Bright zones above price
These are mostly short liquidations. If price rises into the zone, shorts are force-bought, which adds buying pressure and can accelerate the move upward. Traders often describe these zones as magnets: not because of any physical force, but because the market rewards pushing price into places where forced orders wait.
Bright zones below price
These are mostly long liquidations. A dip into the zone triggers forced selling, which is why heavy clusters below price often produce fast, deep wicks followed by sharp recoveries once the forced flow is spent.
The empty space between clusters
Just as informative. When price enters a pocket with little liquidation fuel in either direction, moves tend to slow and chop. Momentum needs fuel, and cleared zones have none left.
Why crypto is uniquely prone to cascades
Liquidation dynamics exist in every leveraged market, but crypto amplifies them in three ways. First, the leverage on offer is extreme: many venues allow 50x to 100x, which places liquidation prices absurdly close to entry. A 100x long is liquidated by a move of well under one percent, so clusters form tightly around every popular entry area. Second, positioning is transparent enough to model. Open interest, funding and volume are public, which is what makes a heatmap possible at all. Third, the market never closes, so cascades can trigger at 4 a.m. on a Sunday when books are thin and there is little resting liquidity to slow them down.
This is why the largest single-hour moves in crypto are almost always liquidation-driven rather than news-driven. The news, when there is any, is merely the spark. The fuel was sitting on the map days in advance.
How traders actually use it
- Target selection. If you are long and a dense short-liquidation band sits 2% above, that band is a rational take-profit area. Price often reaches the fuel, burns it, and stalls.
- Stop placement. Avoid placing your stop inside a dense cluster just beyond an obvious level. Those areas get swept precisely because so many stops and liquidations sit there. Place stops beyond the cluster, or size down.
- Reversal spotting. A violent wick into a major cluster that immediately reverses is the signature of a liquidation sweep. Once the forced orders are consumed, the pressure that caused the move is gone, and the reversal is often tradeable.
- Cascade risk assessment. Stacked clusters in sequence below price signal that one break can chain into the next. That is a reason to reduce leverage, not a prediction that it will happen.
Honest caveats
- It is a model, not an order book. The map estimates where liquidations should sit given leverage assumptions. Real positions may use different leverage or added margin.
- Levels decay. Positions close, get de-risked, or move their liquidation price. Recent clusters are more reliable than old ones.
- Magnets are probabilities, not promises. Price visits dense zones more often than chance, but "often" is not "always". Never trade a heatmap level without price confirmation.
A useful habit is watching the map alongside a live feed of actual liquidations as they fire. The heatmap tells you where the fuel sits; the live feed confirms when it is actually burning, and how much of the projected cluster was real.
