# Fees & Slippage

<details>

<summary><strong>Why didn't my order fill at the expected price?</strong></summary>

Fills use the Quote, incorporating dynamic Impact Cost based on order size. This makes the execution price reflect liquidity conditions at the time of the order. Check execution reports for average fill and costs.

</details>

<details>

<summary><strong>Why is my fee different from other users?</strong></summary>

This could be due to a difference in account type (the Standard account is commission-free, while the Premium account charges a fee per instrument), or a difference in VIP tier among Premium account users that results in different discount rates. You can check your current account type on the Portfolio page.

</details>

<details>

<summary><strong>Will fees on my existing orders change after switching account types?</strong></summary>

Fees on completed historical orders are not recalculated. However, you cannot switch account types while you have open positions or pending orders. Please close or cancel them first, then new orders use the new account type.

<summary><strong>What is slippage? How do I use slippage control?</strong></summary>

Slippage refers to the difference between the expected price at order placement and the actual execution price, typically occurring during periods of high volatility or insufficient liquidity.

Slippage control is a tool MC Markets designed to protect users. You can set your maximum slippage tolerance on the right side of the trading panel. If the execution price exceeds your configured range, the order will be cancelled to avoid filling at an undesirable price. System defaults: regular close operations use a maximum slippage of 10%, and Take Profit/Stop Loss (TP/SL) orders use a maximum slippage of 10%, subject to real-time display on the page and final system settlement.

<details>

<summary><strong>How do I level up my VIP tier?</strong></summary>

Your VIP tier is calculated automatically based on your weighted trading volume over the past 14 days, with volume across all categories aggregated at equal weight (1:1). The higher your trading volume, the higher your VIP tier and the corresponding fee discount.

<summary><strong>Does the Standard account still earn trading points even though it's fee-free?</strong></summary>

Yes. Trading points are now calculated based on effective contract trading volume, not trading fees. Even though Standard Accounts don't charge fees, as long as effective contract trading volume reaches 1,000 USDC within the 7-day tracking period, 80 points are still awarded under the current configuration — the same as any other account. Please refer to the Points page and actual system settlement for final figures.
