A stop and liquidation solve different problems. A stop is an order or rule intended to reduce a position after a chosen trigger. Liquidation is a venue process activated when its maintenance-margin condition is breached. A trader may plan for the stop to act first, but a trigger is not a confirmed fill and cannot guarantee a maximum loss.
Trigger is not fill
A stop trigger can use last, mark, index or another venue-defined reference. After it triggers, a market order can fill beyond the trigger; a stop-limit can remain unfilled. Gaps, book depth, latency, reduce-only rules and order rejection all matter. Liquidation instead follows the venue’s maintenance-margin calculation and may use a different reference price. Keep “triggered,” “sent,” “partially filled” and “closed” as separate states in a research record.
It helps to split the event into three records: which price triggered the instruction, what order the venue activated, and how much actually filled. A position that is only triggered or partly closed still carries exposure. A stop-limit constrains the price but gives no fill certainty; a market-style stop seeks available liquidity but its execution price can differ from the trigger. Check the order’s remaining quantity and whether it is linked to a parent entry, because an entry that fills only partly can leave protection sized or attached differently than expected.
A simplified gap example
Assume a fictional linear long of one unit opened at $100, with $10 isolated collateral and a hypothetical 5% maintenance fraction. Ignoring fees and funding, equity at mark price (P) is (10 + (P - 100)); maintenance is (0.05P). Setting them equal gives (P - 90 = 0.05P), or a simplified maintenance threshold near $94.74. A planned stop trigger at $95 sits above that estimate. But if price gaps from $96 to $93, the stop may fill below $95 or fail to complete before the liquidation process acts. At $93, the simple model has $3 equity against $4.65 maintenance. This is a teaching calculation, not a liquidation-price estimate for any account or venue.
Actual liquidation conditions depend on account equity, notional tiers, maintenance requirements, price references, fees, funding and open orders under the venue’s rules. Cross margin can include other eligible collateral and positions; isolated margin uses its own assigned balance. Never copy the simplified example into a real order plan.
Compare three paths in a hypothetical move
- A gradual move reaches the trigger and an available order closes near the assumed level.
- Price gaps through the trigger and the order closes later at a worse price or remains partly unfilled.
- The mark or account-equity condition reaches the venue’s maintenance threshold before a stop execution completes, so liquidation begins.
These paths illustrate mechanics, not probabilities or a liquidation estimate. A useful study records the trigger source, stop order type, assumed fill, costs, collateral, account mode and venue; it also stress-tests a gap and a partial or missed fill. Planned loss from entry to stop is not a guaranteed cap if execution gaps or liquidation intervenes.
For one current venue-specific example, Hyperliquid uses mark price both to trigger its documented TP/SL orders and in its liquidation process. Sharing a reference price does not merge the two events: the stop activates an order, while liquidation checks account equity against maintenance margin and can initiate a forced book close-out. Hyperliquid says close-outs can fill partially; its TP/SL documentation describes market orders with a slippage tolerance and limit orders whose price constraint can leave them resting unfilled. Its robust-price explanation, TP/SL rules, margining rules and liquidation process are venue-specific examples, not a universal crypto rule. The CFTC virtual-currency advisory warns that losses in margined virtual-currency futures can be amplified and that customers may need to replenish margin or close positions; that advisory does not define every crypto product or jurisdiction.
Audit the actual order before relying on the plan
Write down the venue, contract, account mode, maintenance tier and liquidation reference from current venue documentation or the account interface. Then check which price field triggers the stop and whether it matches the field used in the venue’s maintenance process. Record whether the stop is market or limit, its size, its reduce-only setting, and whether it is attached to a parent entry. Revisit it after adding or reducing position size, transferring collateral or changing other cross-margin positions. A liquidation estimate can move as funding, unrealized PnL, liquidity, tiers or account exposure change; a one-time screenshot is not a lasting guarantee.
For a stress test, compare at least three outcomes from the same position: a continuous move through the trigger with a stated fill assumption, a gap through the stop-limit price that leaves exposure open, and a venue maintenance breach before a stop has fully closed the position. Include fees and funding on the same basis in each path. Keep the order-state log beside the equity and margin ledger so the final result shows what happened to the instruction as well as the account.
SuperQuant can model a stop in a historical simulation, but its engine processes hourly candles with declared gap and intrabar assumptions. It does not place real stop orders or certify exchange execution. Its simplified isolated-margin model cannot reproduce every venue’s liquidation rules, and its bundled histories are synthetic. Describe a simulated stop as a modeled result, not as a verified exchange close.
