Your short position is profitable, the market is moving in your favor, and your account has enough margin. Then part of the position disappears from the open-positions panel. That can happen through auto-deleveraging, or ADL: a derivatives risk-control process that reduces selected positions on the opposite side of distressed positions.
The reason is different from ordinary liquidation. Your own margin may be adequate, but the market’s liquidation process and loss buffers are under pressure. Being right about direction does not guarantee that you can keep the same exposure until you choose to close it.
Why someone else’s liquidation can affect your position
When a leveraged long loses too much equity, the risk engine may take over and close it. In a fast decline, however, available buyers can disappear between the liquidation trigger and execution. The close can leave a loss larger than the collateral supporting that position.
An insurance or security fund can absorb such deficits under the venue’s rules. It is a loss buffer, not a promise that every profitable position will remain untouched. ADL becomes relevant when the applicable backstop cannot absorb the distressed exposure or when specified risk thresholds are reached. Some systems act before a fund is literally empty.
The system then reduces positions on the other side according to its selection rules. During a severe decline, selected shorts can be reduced against distressed longs; during a sharp rise, selected longs can be reduced against distressed shorts. This is not a claim that one named winning trader was the original counterparty to one named losing trader.
KTX’s contract liquidation explanation describes ADL as a possible response when the insurance fund cannot fully cover negative-balance losses. It also says affected positions can be reduced partially or fully. Specific triggers, ranking inputs and execution arrangements should be checked for the actual product.
ADL and liquidation solve different problems
| Event | Why the position changes | Does your own margin have to be insufficient? |
|---|---|---|
| Ordinary liquidation | The applicable margin requirement is no longer met | Yes, at the relevant position or account risk level |
| Auto-deleveraging | The system selects opposite-side exposure to resolve distressed exposure | No |
| Stop-loss or take-profit | A user’s order condition is reached and the resulting order executes | No |
A green PnL number is therefore compatible with ADL. It can even help place a position nearer the front of a selection queue. Conversely, a profitable position under cross margin can still face ordinary liquidation if losses elsewhere undermine the shared account. The event label and transaction history matter more than the color of one position’s PnL.
The KTX guide to liquidation and margin explains that account-risk distinction. A liquidation price estimates a margin boundary; it is not a promise that ADL cannot affect the position before that boundary is reached.
A partial reduction does not automatically erase profit
Consider a hypothetical linear BTC contract quoted and settled in USDT. A trader is short 1 BTC from 70,000 USDT. At a reference price of 60,000, gross unrealized profit is 10,000 USDT. Assume an ADL event closes 0.4 BTC at 60,500, leaving 0.6 BTC open. The assumed settlement price is for arithmetic only, not a KTX pricing rule or current market quote.
The closed portion realizes 0.4 × (70,000 − 60,500) = 3,800 USDT before costs. At the same 60,000 reference price, the remaining portion has 0.6 × (70,000 − 60,000) = 6,000 USDT of unrealized profit. Together that is 9,800 USDT before fees and funding.
The 200 USDT difference from the earlier 10,000 estimate comes from settling the closed portion 500 USDT above the reference price: 0.4 × 500. It is not evidence that all profits vanished. If the closed portion had instead settled at 60,000, its gross realized profit would be 4,000 USDT. Actual records must be reconciled using the applicable contract formula, settlement price and costs.
The other consequence is lost exposure. A further 1,000 USDT decline would generate 600 USDT of additional gross profit on the remaining 0.6 BTC short, rather than 1,000 on the original size. A reversal would also create a smaller loss. ADL changes future participation in both directions.
Ranking is a priority measure, not a countdown
ADL systems commonly consider profitability and leverage, but formulas differ. Effective leverage can depend on current equity, rather than just the leverage setting chosen at entry. Cross margin, isolated margin and portfolio arrangements may also produce different rankings.
Where a venue displays queue bars or lights, they describe selection priority under that venue’s method. They are not a universal probability scale: five lights do not mean an event is certain, and one light is not a guarantee against reduction. Other traders’ positions, equity and the amount requiring offset can change the queue.
Settlement rules differ too. Primary venue documentation includes bankruptcy-price-based and mark-price-based mechanisms. Fees and order-cancellation policies also vary. A formula or fee exemption from another exchange should not be treated as a KTX entitlement. The KTX mark-price and last-price guide explains why reference prices and executable prices are separate concepts.
The biggest surprise may be a broken hedge
Imagine holding 1 BTC in spot and a 1 BTC short to offset price movements. If ADL reduces the short to 0.6 BTC while the spot holding stays unchanged, the simplified combined position becomes net long 0.4 BTC. A 1,000 USDT decline would now produce an approximately 400 USDT combined price loss, before basis changes, funding and fees.
After a reduction, check actual remaining quantities before assuming the strategy is still hedged. Review settlement records, realized PnL, open orders and any protective orders associated with the original size. Some platforms cancel orders during ADL; others apply their own controls. Do not assume every outstanding instruction remains valid.
Reopening the removed quantity can restore exposure, but it is a new trade at new prices and costs. It may also return the account to a similar risk position. Reducing size lowers the quantity exposed; changing collateral may affect some ranking formulas, but neither action guarantees immunity.
Eligible readers can register with KTX and review available contracts through the BTC/USDT perpetual market. The practical task is to know what happens to quantity, settlement and linked orders during stress, rather than treating a favorable price move as protection from every form of forced closure.
Frequently asked questions
Can a low-leverage position be selected?
Yes. Lower leverage may reduce priority under some methods, but selection also depends on the queue and the exposure that must be offset.
Does adding margin prevent ADL?
It can improve the margin buffer and may affect a ranking that uses equity. It does not remove the market-level conditions behind ADL or guarantee exclusion.
Can a stop-loss protect me from ADL?
A stop is an order instruction. It does not opt a position out of the venue’s ADL rules, and it may not execute before the risk engine acts.
Is ADL the same as a funding payment?
No. Funding is a periodic transfer under a perpetual contract’s rules. ADL reduces or closes selected exposure during a risk-control event.
Does ADL mean the whole exchange is insolvent?
Not by itself. It signals stress in the relevant loss-handling process. Its scope and severity require contract-level notices and fund disclosures, not assumptions from one reduction.
