<details>

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

Triggers use Mark Price, not single Last Price trades. Mark Price is a weighted, smoothed fair value to prevent erroneous triggers from spikes. This design reduces the chance of an order being erroneously triggered by a momentary price anomaly.

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

<details>

<summary><strong>Why can't I open or add to a position?</strong></summary>

Once an account's margin ratio enters the Risk Warning Tier, the system restricts new position openings and additions, including market orders, limit orders, and order modifications or new conditional orders that would increase margin usage.&#x20;

This is a risk-control mechanism, not a system malfunction. You can still close or reduce positions, and you can modify TP/SL on existing positions (this is not restricted, but does not change margin usage). To resume placing orders, close positions, reduce positions, or add margin to bring your margin ratio back to a normal level.

</details>

<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 at the top of each hour. When the market is imbalanced, the dominant side pays the other side. Please refer to the trading interface for the current displayed rate.

</details>

<details>

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

Leverage options are already available when you select an instrument, with no need for separate setup. Specific leverage for each instrument is subject to real-time display on the trading page.

</details>

<details>

<summary><strong>If my account holds multiple types of collateral, which one gets used first during liquidation?</strong></summary>

If there are unfilled pending orders, the system cancels them first to release the margin they were using. Multiple types of collateral are then used or deducted in the order USDC, USDT, BTC, ETH, SOL. If multiple positions need to be liquidated, the system closes them from largest to smallest position value until your account is back within the Maintenance Margin Ratio requirement. If your account still shows a negative balance after the collateral is exhausted, the system zeroes out the negative balance — MC Markets absorbs the resulting loss.

</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>Are there fees for liquidation? Why did my balance drop after liquidation?</strong></summary>

The platform does not charge a liquidation fee. The change in balance after liquidation comes from the actual loss on the position and other account-level adjustments, which can be verified against the position, trade, and transaction records.

</details>

<details>

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

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

1. 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.
2. 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 reduces the chance of an order being erroneously triggered by abnormal price volatility.

</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, please try the following:

* Check Positions to confirm the remaining instrument and quantity.
* Check Open Orders, Order History, and Trade History for the close-order status and fill quantity.
* Note the action time and any page message. Avoid guessing at a cause or resubmitting the close action again until you've reviewed the records above.
* Refresh once. If the records still don't explain the result, contact Live chat with the instrument, remaining quantity, close-order status, action time, and screenshots.

</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.

</details>

<details>

<summary><strong>What is the minimum order quantity for US500 and other index perpetuals?</strong></summary>

Current minimum order quantities are: US500 – 0.1, NAS100 – 0.01, US30 – 0.01 (with minimum price movements of 0.1, 0.1, and 1 respectively). No single fixed minimum notional is shown on the page — the minimum order value works out to roughly $100. Please check the live Trading Rules on the Perpetuals page, as specs may be updated over time.

</details>

<details>

<summary><strong>Does MC Markets currently support stock and forex perpetuals?</strong></summary>

Yes. MC Markets' perpetuals cover crypto, forex, indices, precious metals, energy, and stock-reference instruments. Stock perpetuals currently listed are major blue-chip names on Nasdaq and NYSE. The exact lineup is updated on an ongoing basis.

</details>

<details>

<summary><strong>Why might a limit order remain unfilled after the price is reached?</strong></summary>

If a limit order stays open, first check the limit price, filled quantity, and order status under Open Orders. Common reasons include:

* No opposing liquidity is currently available at your limit price or better
* Other orders are ahead of yours in the queue at the same price
* Insufficient liquidity means only part of the order can be filled

</details>

<details>

<summary><strong>Why might a limit order show a price-protection warning or be rejected?</strong></summary>

Before submission, a limit order is checked against the page's price-protection and input-validation rules, designed to prevent unnecessary losses from input errors. Common rules include:

* Normal resting orders are unaffected: when going long, the limit price can be below the current best ask; when going short, it can be above the current best bid — these orders simply rest as pending orders and are not rejected solely for that price relationship;
* Deviation warning: when the limit price deviates from the reference price by more than roughly 3% (subject to the live page), the system shows a warning prompt requiring confirmation before submission — orders with an excessive deviation in the risky direction (e.g., a buy priced far above market) may be rejected outright;
* Other common rejection causes include insufficient account balance or a slippage setting that's too tight.

The exact reference price and final outcome are subject to what's shown on the live page and the system's actual settlement. If the issue persists after checking your balance and order parameters, please contact support via an in-platform ticket with your order ID so the technical team can investigate.

</details>

<details>

<summary><strong>At what margin ratio are warnings and forced liquidation triggered?</strong></summary>

When your margin ratio falls below 100%, the system issues a Margin Call warning, prompting you to add margin or reduce your position. If the margin ratio drops further, to below 50%, the system automatically triggers forced liquidation.

</details>

<details>

<summary><strong>How do I confirm a perpetual instrument's minimum order quantity and minimum price movement?</strong></summary>

These parameters vary by instrument, so the most reliable way is to click the "Trading Rules" tab next to the instrument name on the trading page. It shows the minimum order quantity, minimum price movement (tick size), max trade size, and more for that specific instrument, all subject to the live page and actual system settlement rather than any static list.

</details>

<details>

<summary><strong>What information and controls are currently available on the Depth Chart?</strong></summary>

The Depth Chart shows the cumulative quantity distribution of buy and sell orders for the current trading pair, useful for inspecting order-book liquidity. Switch to Depth Chart in the chart area of the trading page, the current interface clearly displays fields such as Price and Quantity.

</details>

<details>

<summary><strong>Where can I view pending, filled, and cancelled orders?</strong></summary>

* Pending (unfilled) orders: check Open Orders below the trading chart
* Filled or cancelled orders: check Order History
* Detailed execution info (e.g., average fill price, impact cost): check Trade History

</details>
