Your Liquidation Price Is Not Where You Think.
By CryptoTraders · Market Education · 2026-07-18
Ask a new perp trader where their liquidation price is and you get a shrug or a guess. Ask them after their first liquidation and they know the number to the cent. The line was always computable in advance. Most people just never look until they have crossed it.
The mechanics, in plain terms
When you open a leveraged position, you post initial margin, the collateral backing the trade. The exchange also defines maintenance margin, the minimum collateral the position must keep as it moves. Liquidation is nothing more than the price at which your remaining margin would fall below that maintenance requirement. The engine closes the position by force at that point because beyond it, losses would exceed what you posted, and the exchange is not in the business of absorbing your deficit.
This is why leverage moves your liquidation price closer. At higher leverage you posted less margin for the same position, so a smaller adverse move exhausts it. Roughly, at 10x an adverse move somewhat under 10% reaches the line, at 25x under 4%, at 50x under 2%, with the exact distance shortened further by fees and the maintenance requirement itself. And a detail that catches many: on most venues the calculation runs on mark price, an index-based fair price, not the last traded print, precisely so that one manipulated wick on one book cannot liquidate you by itself. It also means you can be liquidated without your entry venue ever printing your level.
Cascades, insurance funds, and ADL
One liquidation is arithmetic. Many at once is weather. Forced closes are market orders, so a cluster of liquidations pushes price into the next cluster, which is how cascades turn a 3% move into a 12% one on a leveraged pair. Exchanges maintain insurance funds to absorb the shortfall when a position closes worse than its bankruptcy price, and in extreme cases fall back on auto-deleveraging, closing winning traders' positions to balance the books. If you have ever had a winning position trimmed during a violent move, that was ADL, and it is the system telling you how stressed the venue was.
What to do with this
Three habits. Know the number before you enter: every exchange shows the liquidation price at order time, and if you would not accept that price being hit, the size is wrong. Keep the line far behind your stop: your stop is where the trade idea dies, and liquidation should be far beyond it, a backstop you never intend to test, because dying by stop costs your planned R while dying by liquidation costs the whole margin plus fees. And in cascade conditions, respect that the liquidation map is the move: heatmap clusters, which we covered in the stop-map post, mark exactly where these chains detonate.
Liquidation is not bad luck. It is a computable line that sizing either respects or does not. The traders who last are not the ones who never get stopped. They are the ones who never meet the other line.
