<details>

<summary><strong>Why didn’t my stop-loss or take-profit trigger when the Last Price reached the target?</strong></summary>

Stop-loss and take-profit orders trigger based on **Mark Price**, not the Last Price of a single trade. Mark Price is a weighted, smoothed fair value that prevents accidental triggers caused by sudden price spikes, protecting your positions.

</details>

<details>

<summary><strong>Where can I view funding rate history?</strong></summary>

You can find it below the trading interface in the **Funding Fee History** section.

</details>

<details>

<summary>What should I do if my order is rejected?</summary>

Common causes include: insufficient balance, slippage tolerance set too low, or limit price too far from the best available price. For long positions, the limit price cannot be below the current best ask; for short positions, it cannot be above the current best bid. Please check your balance and order parameters and try again. If the issue persists, please contact our support team via the in-platform ticket system and include your order ID — our technical support team will investigate.

<details>

<summary><strong>What is Mark Price? Why is it used to calculate liquidation?</strong></summary>

Mark Price is the platform's fair value benchmark, aggregated from multiple external oracle prices and internal data. It's used for PnL calculations, liquidations, and risk controls to prevent manipulation from anomalous trades. Mark Price may differ from the Last Price. All trigger orders and liquidations are based on Mark Price rather than the Last Price, which is more easily manipulated.

</details>

<details>

<summary><strong>How often is the funding rate settled?</strong></summary>

Funding rates are settled once every hour, on the hour. The system recalculates and updates the rate every minute, displayed live on the trading interface. When the market is imbalanced, the dominant side pays the funding rate to the other side. You can check the current rate on the trading interface to estimate your holding cost in advance.

</details>

<details>

<summary><strong>How do I adjust leverage?</strong></summary>

Leverage is fixed and varied per instrument. The maximum leverage is determined automatically based on your position's notional value, Larger positions require a higher Maintenance Margin Ratio (MMR) and are subject to lower maximum leverage. Refer to each instrument's leverage tier table for specifics.

</details>

<details>

<summary><strong>Where can I check my liquidation price?</strong></summary>

You can see your liquidation price on the trading page. Go to the \[Positions] tab and look for your liquidation price under the \[Liquidation Price] section. Please note that the Margin Call threshold is 100%, and forced liquidation is triggered at 50%. Liquidation is based on Mark Price.

</details>

<details>

<summary><strong>How do I set a profit / stop loss?</strong></summary>

Take Profit and Stop Loss are automated position-closing tools that can be set in two ways:

* At order placement: expand the "TP/SL" option on the order panel and enter your target price; TP/SL activates automatically once the order fills.
* After opening a position: find the position in your position list, click the "TP/SL" button, and enter or edit your target price to confirm.

All TP/SL orders are triggered based on Mark Price, not Last Price, which effectively prevents orders from being triggered erroneously by abnormal price spikes.

</details>

<details>

<summary><strong>What is "Close All"? Why is my position still open after clicking it?</strong></summary>

"Close All" is located at the top-right of your position list and closes all open positions at once when clicked.

If a position remains open after clicking it, possible reasons include:

* The page hasn't refreshed yet, causing a display delay
* Some positions were only partially filled due to insufficient liquidity
* A brief network or system issue

We recommend refreshing the page first to confirm. If the position still shows as open, please submit a support ticket with the Order ID and a timestamped screenshot so we can investigate.

</details>

<details>

<summary><strong>Is the margin mode cross or isolated?</strong></summary>

MC Markets currently supports Cross Margin. All available funds in your account can serve as a shared margin across your positions, improving capital efficiency and helping prevent premature liquidation of individual positions. Isolated Margin is not currently supported.

</details>

<details>

<summary><strong>Can I partially close a position?</strong></summary>

Yes, you can close your position partially. In the \[Positions] tab, click either \[Market] for a market close, or \[Limit] for a limit close, then use the slider or type in the quantity directly to set how much of your position you want to close.

</details>

<details>

<summary><strong>What order types are supported?</strong></summary>

Both spot and perpetual contracts support Market and Limit orders; perpetuals additionally support Take-Profit/Stop-Loss (TP/SL) orders.&#x20;

* Market orders execute instantly at the best available price.
* Limit orders trigger when the price reaches your set level.
* TP/SL orders trigger based on the Mark Price.&#x20;

Switch between Market/Limit above the \[Buy]/\[Sell] buttons. TP/SL can be set on the order panel or added to an existing position.
