A liquidation map shows the price levels where leveraged futures positions would be forced out if the price reached them. When many longs sit just below the price, a fall to that zone can trigger a chain of forced sales; when many shorts sit just above it, a rise can trigger forced buying. This page draws such a map for Bitcoin and Ethereum perpetual futures on Binance: red bars below the price are longs, green bars above are shorts, and a white line adds up the volume you would meet if the price travelled that far.
No exchange publishes where individual positions will be liquidated, because that would reveal other traders' positions. What Binance does publish is the open interest history, candles and the forced orders that already happened. The map on this page is therefore a model, not exchange data. Other services model it with their own assumptions, so their pictures differ from ours and from each other. We show the assumptions under the chart instead of hiding them.
Every time open interest grows during a 15-minute bar, we assume new positions were opened around the typical price of that bar. Their side is unknown, so we split them equally between longs and shorts, and we assume a mix of leverage from 5x to 100x with a maintenance margin of 0.4%. Each position gets a liquidation price. When open interest falls, positions are closed proportionally, and when the price later trades through a level, the positions there are removed as liquidated. The window is 29 days, because Binance serves open interest history only for the last month.
Below the chart we compare what the model says was liquidated over the last 24 hours with what the Binance liquidation stream reported. The stream sends at most one forced order per coin per second and our recording started recently, so it is a lower bound. We do not claim the map predicts price: a cluster of liquidations is a place where forced orders may add fuel to a move, not a promise of a move. Treat it as context, and read it together with the live Liquidations page.
No. Binance does not publish one. This is an estimate calculated from open interest and price history with stated assumptions.
Each service assumes its own leverage mix, long and short split and time window. The result is a model, so the pictures differ.
No. It shows where forced orders may appear if the price gets there. It does not say that the price will.
Bitcoin and Ethereum for now. More coins can be added if the model proves useful.
