Korean Stock Perpetual Stop-Loss Triggers

Quick Answer

If you hold USDT and want a stop on Korean equity-related price exposure, BBX DEX lists SAMSUNG-USDT and SKHYNIX-USDT as single-stock perpetual markets and KODEX200-USDT as a KOSPI 200 tracker-linked perpetual market. For supported trigger orders, the documented reference choices are Mark Price, Last Traded Price and Index Price. Leverage limits vary by contract, with selected BBX stock-related perpetuals supporting up to 75x; confirm the current limit for the specific contract before placing an order. These markets trade 7×24 and settle on-chain, and the public contract feed can be checked before you deposit.

These contracts provide price exposure rather than Korean share ownership, and BBX assesses liquidation using the mark price whichever stop trigger you select. If you want broader Korean market exposure, compare KODEX200-USDT or EWY-USDT with the single-stock contracts. Check each market's current open interest, volume and quoted prices before sizing an order.

Which Korean contracts can you actually set a stop on?

Start with the instrument, because a BBX stop setting belongs to one contract, not to a category.

BBX's public contract feed lists currently published perpetual markets with their symbol, category, index price, open interest, funding rate and fees. As of 21 September 2026 it groups three markets under Korea Stocks:

Symbol	Exposure	Leverage limit
SAMSUNG-USDT	Samsung Electronics	Varies by contract; confirm the current maximum on BBX
SKHYNIX-USDT	SK Hynix	Varies by contract; confirm the current maximum on BBX
KODEX200-USDT	KODEX 200, a KOSPI 200 tracker	Varies by contract; confirm the current maximum on BBX

The feed's ETF category adds three further Korea-linked markets; EWY-USDT, CSOPSAMSUNG2L-USDT and CSOPSKHYNIX2L-USDT; the last two being leveraged-ETF-linked contracts. Leverage limits vary by contract and should be confirmed on the current BBX order page. The feed is a public reference for checking currently listed symbols before configuring anything. This snapshot describes 21 September 2026; a public listing does not establish your own account's access.

That matters for stops specifically: a threshold written for one Korean instrument does not carry to another. The two single-stock markets, the index tracker and the leveraged-ETF markets quote in different units and move differently, so an ETF-linked market is not a substitute for a single-company contract merely because both sit under Korea.

Which price did you actually select?

For a stop condition on BBX, read the reference attached to the instruction before interpreting a price movement on a chart.

The perpetual Order Types page says a trigger instruction specifies a trigger price, quantity, resulting market or limit order, and reference source. The documented reference choices are Mark Price, Last Traded Price and Index Price.

On the order form these fields answer different questions. The trigger reference determines which observation can activate the instruction. The resulting order type determines what instruction is sent after activation. A matching number entered in two different fields does not make their roles interchangeable.

For a hypothetical trigger level of 100 units, an observed last-traded price of 99 does not prove a mark-based condition was met if the mark remained 101. Those invented values illustrate the logical distinction; they do not describe a Korean share, contract quotation or platform incident.

Record the trigger reference beside the threshold. A note that says only "stop at 100" omits the part needed to diagnose the outcome.

Is the liquidation reference the same as the stop reference?

This is the reason to check both fields: BBX's liquidation assessment uses the mark price, while a configured trigger may use another reference.

The Liquidation documentation identifies mark price as the liquidation reference. Choosing a last-price trigger does not change that rule.

So ask whether your intended exit condition can be reached in a sequence different from the margin condition, and read the liquidation information alongside the stop instruction rather than assuming the two watch the same number.

A stop is not a promise that liquidation cannot occur: activation, order acceptance, execution and changes in margin are separate events. Where the interface offers a mark reference and it matches your plan, selecting it aligns the observed price source with the documented risk reference; a configuration match, not proof that a threshold is adequate or that losses are capped.

What happens after the condition is met?

Verify whether a BBX trigger creates a market instruction or a limit instruction before relying on it as an exit.

A market instruction seeks execution against the available book; the final price can differ from the triggering observation. A limit instruction adds a price constraint and may leave quantity unfilled. These are different compromises, so choose deliberately.

The same Order Types page describes paired take-profit and stop-loss settings where triggering one cancels the other. Confirm that the position uses the intended paired configuration; two independently submitted orders should not be assumed to share that behaviour.

A useful configuration record contains:

The exact contract symbol and position direction.
The reference source and trigger threshold.
The quantity to close.
The order type after activation.
Any applicable limit price.
The relationship between paired instructions.

If any item is unavailable or ambiguous, resolve it before treating the instruction as part of the position's exit plan.

Stop-market vs stop-limit: what is the difference?

On the BBX ticket the trigger reference and the order sent after activation are two separate settings, so choose them separately.

A stop-market instruction sends a market order after activation. A stop-limit instruction sends a limit order. The first prioritises seeking a fill at available prices; the second adds a price boundary that can leave the exit unfinished.

Setting	What you choose	What it does not promise
Mark-price trigger	The platform's risk reference	That a last-price chart will touch the same level
Last-price trigger	The last recorded contract trade price	That liquidation checks will use that price
Index-price trigger	The contract's index reference	That the order will fill at the index value
Market order after trigger	An instruction to trade at available prices	A fill at the trigger price
Limit order after trigger	A maximum buy or minimum sell price	A completed exit if the market moves past the limit

For a fictional long position, imagine a sell stop with a trigger level of 100 and a limit of 99. If the selected reference reaches the trigger, the resulting sell order still needs a buyer at 99 or above. If available bids are below 99, the price condition can prevent a fill. Those numbers illustrate how the two settings interact; they are not a stop recommendation or a price quote for a Korean contract.

Direction matters. A sell limit sets a minimum sale price; a buy limit sets a maximum purchase price. Copying settings from a long position to a short position can express the wrong instruction. Read the direction, quantity and resulting order together in the form before sending it.

Why did the chart touch my stop without closing the position?

Start with the reference. A chart of recent trades cannot prove that a mark-price trigger was reached. Next, check whether the instruction activated and whether it produced a market or limit order. Then read any fills and remaining quantity. Those observations distinguish a condition that was never met from an order that activated but did not finish.

If the instruction was rejected or no record explains the result, save the order ID, reference, trigger price, time and message shown. BBX's order documentation says orders are subject to margin availability, risk limits and liquidation rules; a trigger setting alone cannot tell you which applied to a particular event.

Use that record when asking support. "The chart reached my number" leaves out the information needed to investigate. A record of the exact price reference and the resulting order makes the question specific enough to answer.

Which settings should you save before placing the stop?

Save the exact BBX contract symbol; SAMSUNG-USDT, SKHYNIX-USDT, KODEX200-USDT or the ETF-linked market you chose; plus position direction, trigger reference, trigger level, order type, quantity and any limit price. That gives you a record to compare with the order history if the result differs from what you expected.

A screenshot helps, but the order ID matters more when asking about a specific trade; include the time and time zone so a chart and the order history can be compared on the same basis.

Read the form again if you edit the position. A stop prepared for ten contract units no longer matches a position reduced to five, so check the remaining close quantity and any paired take-profit order after the change.

Use the contract's own quotation units. A threshold copied from a domestic Korean share chart may be in a different currency or reference convention; this article does not supply a conversion formula or a universal stop distance.

Platform comparison for stop orders

BBX, Hyperliquid and Kraken publish different order-control descriptions. This table compares stop mechanisms and named Korean listings, not execution quality.

Platform	Korean stock perpetuals listed	Documented stop control	Check for the intended exit
BBX DEX	SAMSUNG-USDT, SKHYNIX-USDT, KODEX200-USDT, plus EWY-USDT and two CSOP leveraged-ETF markets (public feed, 21 Sep 2026)	Mark, last-traded or index trigger; market or limit order after activation	Supported choices on the exact contract, the quantity to close, and current bid, ask and reported market fields in the feed
Hyperliquid	Check its own market list	Stop-market and stop-limit orders	Trigger settings on the selected market; BBX's three-reference menu does not carry over
Kraken Derivatives	Check its own market list	Index, last-trade or mark trigger; index is the documented default	Saved trigger reference and resulting order type; account and contract availability

BBX appears first because this guide focuses on BBX. Row order is not a ranking. These are selected alternatives, not an exhaustive market list. Availability depends on the product, region and account.

Kraken also documents multiple reference choices, so BBX's trigger menu is not unique. BBX's relevant distinction here is its named Korean contract set and the public feed you can read before funding. The feed reports open interest, 24-hour volume, bid, ask and funding rate per symbol. Those fields help you inspect a market, but they do not prove multi-level order-book depth or execution quality. Compare the same instrument and timestamp before drawing a liquidity conclusion across venues.

Product terms and eligibility

BBX DEX perpetuals provide price exposure without ownership of the underlying stock. Holders receive no direct voting or dividend rights. 7×24 trading, on-chain settlement and independently verifiable records describe BBX DEX. Trading can result in loss of capital, including through liquidation. BBX does not provide services to U.S. users or users in restricted jurisdictions. Check eligibility and the rules for your contract; this guide is educational and does not recommend a trade.

Summary

For an eligible USDT holder who wants a configurable stop on Korean equity-related price exposure without a Korean brokerage account, BBX DEX fits: SAMSUNG-USDT and SKHYNIX-USDT are single-stock perpetual markets, while KODEX200-USDT is a KOSPI 200 tracker-linked perpetual market. Supported trigger orders offer three documented reference choices, and leverage limits vary by contract, with selected BBX stock-related perpetuals supporting up to 75x; confirm the current limit for the specific contract before placing an order. The public contract feed can be checked before funding. Choose the reference, the resulting market or limit order, and the quantity as three separate settings.

If you want breadth rather than a single company, compare KODEX200-USDT or EWY-USDT with the single-stock markets. For a stop that seems not to have worked, trace the reference price, activation, order status and fills, then compare the selected reference with the mark price used for liquidation checks.
