How Guaranteed Stop Loss (Guaranteed SL) Works

The Guaranteed Stop Loss (Guaranteed SL) feature helps traders protect their positions and manage risk more effectively during periods of high market volatility. When this mode is enabled, the stop-loss order is guaranteed to be executed at the specified price or better, preventing slippage.

Example

Trader A is holding a Long position at 106,000 USDT. To protect capital, A sets a Stop Loss at 105,500 USDT and enables Guaranteed SL.

  • When the Last Price reaches 105,500 USDT, the system triggers the stop loss and places a reduce-only limit order to reduce or close the position.

  • This order will only be filled at 105,500 USDT or higher, ensuring that losses do not exceed the planned level.

To optimize system performance and maintain stability during periods of extreme market volatility, ONUS has updated several operating rules for Guaranteed SL, as outlined below:

1. Pre-Funding Handling Rules

To ensure system stability around the funding time, when abnormal price fluctuations or sharp funding rate changes may occur:

Within 2 minutes before the funding time, if the Guaranteed SL premium fee is lower than the absolute value of the Funding Rate, the system will automatically process the order as a regular Stop Loss, meaning:

  • The order may experience slippage and is no longer price-guaranteed.

  • No premium fee will be charged; only standard trading fees apply.

Example

  • Funding time for the BTC/USDT pair is 07:00.

  • At 06:58, if:

    • Funding Rate = –0.03%

    • Guaranteed SL premium = 0.01%

Since 0.01% < |–0.03%|, any Guaranteed SL order placed during this period will be treated as a regular Stop Loss, which may be subject to slippage and will not incur a premium fee.

2. Validity Checks for Guaranteed Stop Loss Orders

To ensure accurate execution, ONUS will automatically validate Guaranteed SL orders when they are created and again before they are triggered.

You will not be able to place the order, or the order will be automatically canceled upon trigger, if:

  • Guaranteed SL trigger price ≥ Entry Price for Long positions, or

  • Guaranteed SL trigger price ≤ Entry Price for Short positions.

Example

  • You open a Long BTC position with an initial entry price of 106,000 USDT and set a Guaranteed SL at 105,900 USDT.

  • Later, you add to the position (DCA), causing the average entry price to drop to 105,800 USDT.

  • In this case, the Guaranteed SL price (105,900 USDT) exceeds the entry price, so the Guaranteed SL order will be automatically canceled when triggered.

Premium Fee

ONUS Pro applies a premium fee when users place a Guaranteed Stop Loss order. The premium rate is determined based on the risk level and price spread of each trading pair. This fee is:

  • Clearly displayed when placing the order

  • Charged only if the order is executed

Fee Formula

Guaranteed SL Fee = Execution Price × Position Size × (Taker Fee Rate + Premium Rate)

  • The user’s VIP level determines the Taker fee rate.

  • Users can view the premium fee:

    • In the Stop Loss settings of an open position, or

    • In the Trading Info section of each trading pair.
