#FAQ#Trading Fee

<p><span style="font-weight: 400;">MEXC offers two kinds of contracts: USDT-M and COIN-M contracts. The USDT-M contract is quoted in USDT and settled in USDT while the COIN-M contract is quoted in USDT and settled in BTC. The principle of calculation is similar but there are some slight differences. Please note that during the calculation, trading fee and other complex components will not be taken into account. The aim is to explain how margin is calculated to users.</span></p> <p> </p> <ol> <li><strong> Margins Explained</strong></li> </ol> <p><span style="font-weight: 400;">All MEXC perpetual contracts require a certain amount of margin to open a position.</span></p> <p><span style="font-weight: 400;">Successful margin trading requires an understanding of the following concepts:</span></p> <p><strong>Starting Margin</strong><span style="font-weight: 400;">: This minimum margin required to open a position. Your starting margin is dependent on margin rate requirements.</span></p> <p><strong>Maintenance Margin</strong><span style="font-weight: 400;">: The minimum margin requirement for maintaining a position below which additional funds will have to be deposited or forced liquidation may occur.</span></p> <p><strong>Opening Cost</strong><span style="font-weight: 400;">: The total amount of funds required to open a position, including the initial margin for opening a position and transaction fees.</span></p> <p> </p> <ol start="2"> <li><strong> Margin calculation</strong></li> </ol> <p><span style="font-weight: 400;">In perpetual contracts, the order cost is the margin required to open a position. The actual cost is determined by whether the order is executed by a maker or taker because varying fees apply.</span></p> <p><em><span style="font-weight: 400;">COIN-M contract: Order cost (margin) = number of open positions * futures size / (leverage multiplier * avg. entry price)</span></em></p> <p><em><span style="font-weight: 400;">USDT-M contract: Order cost (margin) = avg. entry price * number of open positions * futures size / leverage multiplier</span></em></p> <p> </p> <p><span style="font-weight: 400;">Examples:</span></p> <p><strong>COIN-M Contracts</strong></p> <p><span style="font-weight: 400;">If a trader wants to purchase 100 BTC/USDT perpetual contracts at the price of 7,000USD with a leverage multiplier of 25, and the value of each contract is 100 USD, then the margin required = 100x100 / (7000x25 ) = 0.0571BTC.</span></p> <p> </p> <p><strong>USDT-M Contracts</strong></p> <p><span style="font-weight: 400;">If a trader wants to purchase 10,000 BTC/USDT perpetual contracts at the price of 7,000USDT with leverage multiplier of 25, and the value of each contract is 0.0001BTC, then the margin required = 10000x0.0001x7000/25 = 280 USDT.</span></p> <p> </p> <ol start="3"> <li><strong> PNL Calculation</strong></li> </ol> <p><span style="font-weight: 400;">PNL calculation includes fee income or expenditure, funding fee income or expenditure, and PNL upon closing a position.</span></p> <p><strong>Fee</strong></p> <p><span style="font-weight: 400;">The expenditure of the taker  = Position value * Taker fee </span></p> <p><span style="font-weight: 400;">The expenditure of the maker = Position value * Maker fee</span></p> <p><strong>Funding fee</strong></p> <p><span style="font-weight: 400;">According to the negative or positive funding fee rate and the long or short position held, the trader will pay or receive funding fee.</span></p> <p><span style="font-weight: 400;">Funding fee = funding fee rate * position value</span></p> <p><span style="font-weight: 400;">Note: The position value is calculated from the fair price when the funding fee rate is settled.</span></p> <p><strong>Closing PNL:</strong></p> <p><em><span style="font-weight: 400;">USDT-M Contract</span></em></p> <p><span style="font-weight: 400;">Long position = (exit price - avg. entry price) * number of holding positions * futures size</span></p> <p><span style="font-weight: 400;">Short position = (avg. entry price - exit price) * number of holding positions * futures size</span></p> <p><em><span style="font-weight: 400;">COIN-M Contract</span></em></p> <p><span style="font-weight: 400;">Long position = (1/avg. entry price - 1/avg. exit price) * number of holding positions * futures size</span></p> <p><span style="font-weight: 400;">Short position = (1/avg. exit price - 1/avg. entry price) * number of holding positions * futures size</span></p> <p><strong>Floating PNL</strong></p> <p><em><span style="font-weight: 400;">USDT-M Contract</span></em></p> <p><span style="font-weight: 400;">Long position = (fair price - avg. entry price) * number of holding positions * futures size</span></p> <p><span style="font-weight: 400;">Short position = (avg. entry price - fair price) * number of holding positions * futures size</span></p> <p><em><span style="font-weight: 400;">COIN-M Contract</span></em></p> <p><span style="font-weight: 400;">Long position = (1/avg. entry price - 1/fair price) * number of holding positions * futures size</span></p> <p><span style="font-weight: 400;">Short position = (1/fair price - 1/avg. entry price) * number of holding positions * futures size</span></p> <p> </p> <p><span style="font-weight: 400;">For example, a trader purchases 10,000 cont. long for BTC/USDT perpetual contract at the price of 7,000USDT as a taker. If the taker fee is 0.06%, the maker fee is 0.02%, the funding fee rate is -0.025%, and the current fair price is 7000USDT, then the trader shall pay a taker fee of:</span></p> <p><span style="font-weight: 400;">7000*10000*0.0001*0.06% = 4.2USDT</span></p> <p><span style="font-weight: 400;">and the trader pays a funding fee of:</span></p> <p><span style="font-weight: 400;">7000*10000*0.0001*-0.025% = -1.75USDT</span></p> <p><span style="font-weight: 400;">In this situation, the negative value means that the trader receives the funding fee instead.</span></p> <p> </p> <p><span style="font-weight: 400;">When said trader closes 10,000 cont. BTC/USDT perpetual contract at 8,000USDT, then the closing PNL is:</span></p> <p><span style="font-weight: 400;">(8000-7000) *10000*0.0001 = 1000 USDT</span></p> <p><span style="font-weight: 400;">And the closing fee can be calculated as follows:</span></p> <p><span style="font-weight: 400;">8000*10000*0.0001*0.02% = 1.6 USDT</span></p> <p><span style="font-weight: 400;">Hence, the realized PNL of the trader = 1000+1.75-4.2-1.6 = 995.95 USDT</span></p>

<p><strong>Limit Order</strong></p> <p><span style="font-weight: 400;">Limit orders allow the trader to set a specific buying or selling price, and the order will be filled at the order price or at a price more favorable than the order price. </span></p> <p><span style="font-weight: 400;">When a limit order is submitted, if there is no order of which price is more favorable than or equal to the order price available for matching in the order book, the limit order will enter the order book to be filled, increasing the market depth. After the order is filled, the trader will be charged according to the more favorable maker fee.</span></p> <p><span style="font-weight: 400;">When a limit order is submitted, if an order of which price is more favorable than or equal to the order price is already available for matching in the order book, the limit order will be immediately filled at the current best available price. Because of the liquidity consumed during the order execution, a certain trading fee will be charged as the Taker fee expense.</span></p> <p><span style="font-weight: 400;">In addition, limit orders can also be used to partially or fully close a take profit limit order. The advantage of a limit order is that it is guaranteed to be filled at the specified price, but there also exists a risk that the order will not be filled.</span></p> <p><span style="font-weight: 400;">When using a limit order, the user can also switch the effective time type of the order according to their trading needs, and the default is GTC:</span></p> <p><span style="font-weight: 400;">- GTC (Good ‘Til Canceled Order): This type of order will remain valid until it is fully filled or canceled.</span></p> <p><span style="font-weight: 400;">- IOC (Immediate or Cancel Order): If this type of order cannot be filled immediately at the specified price, the unfilled part will be canceled.</span></p> <p><span style="font-weight: 400;">- FOK (Fill or Kill Order): This type of order will be canceled immediately if all orders cannot be filled.</span></p> <p> </p> <p><strong>Market Order</strong></p> <p><span style="font-weight: 400;">The market order will be filled at the best price available in the order book at the time. The order can be quickly filled without having the trader set the price. The market order guarantees the execution of orders but not the execution price, as it may fluctuate depending on market conditions. Market orders are typically used when a trader needs to make a quick entry to capture a market trend.</span></p> <p> </p> <p><strong>Trigger Limit Order</strong></p> <p><span style="font-weight: 400;">If the trigger price is set, when the benchmark price (market price, index price, fair price) selected by the user reaches the trigger price, it will be triggered, and a limit order will be placed at the order price and quantity set by the user.</span></p> <p> </p> <p><strong>Stop Market Order</strong></p> <p><span style="font-weight: 400;">If the trigger price is set, when the benchmark price (market price, index price, fair price) selected by the user reaches the trigger price, it will be triggered, and a market order will be placed with the quantity set by the user.</span></p> <p><span style="font-weight: 400;">Note:</span></p> <p><span style="font-weight: 400;">The user's funds or positions will not be locked when setting the trigger. The trigger may fail due to high market volatility, price restrictions, position limits, insufficient collateral assets, insufficient closeable volume, futures in non-trading status, system issues, etc. A successful trigger limit order is the same as a normal limit order, and it may not be executed. Unexecuted limit orders will be displayed in active orders.</span></p> <p> </p> <p><strong>Trailing Stop Order</strong></p> <p><span style="font-weight: 400;">A trailing stop order is a strategy order for tracking market prices, and its trigger price may change with latest market fluctuations.</span></p> <p><span style="font-weight: 400;">Trigger price calculation:</span></p> <p><span style="font-weight: 400;">Sell, Actual Trigger Price = Market's Historically Highest Price - Trail Variance (Price Gap), Or Market's Historically Highest Price * (1 - Trail Variance %)</span></p> <p><span style="font-weight: 400;">Buy, Actual Trigger Price = Market's Historically Lowest Price + Trail Variance, Or Market's Historically Lowest Price * (1 + Trail Variance %)</span></p> <p><span style="font-weight: 400;">Trailing orders allow users to select an activation price for the order, and the system will start calculating the trigger price only after the order is activated.</span></p> <p> </p> <p><strong>Identification for Trailing Stop Order</strong></p> <p><span style="font-weight: 400;">Trail variance: The trail variance is the main condition for calculating the actual trigger price. The actual trigger price will be calculated based on the highest/lowest price of the specified price type after the order activation and the trail variance.</span></p> <p><span style="font-weight: 400;">Quantity: The number of orders placed.</span></p> <p><span style="font-weight: 400;">Price type: You can select the last transaction price, fair price or index price as the criteria to activate and trigger trailing orders.</span></p> <p><span style="font-weight: 400;">Activation price: Activation price is the activation condition of a trailing order. When the price of the specified price type reaches or exceeds the activation price, the order will be activated. The system will only start calculating the actual trigger price upon activation. If the activation price is not defined, the order will be  activated upon placement.</span></p> <p><span style="font-weight: 400;">For example:</span></p> <p><span style="font-weight: 400;">Case 1 (Sell the rip): The user wants to sell BTC without selecting the activation price (i.e. activate as soon as the order is placed) and the last transaction price is 30,000 USDT.</span></p> <p><span style="font-weight: 400;">Then, one may set the parameters as follows.</span></p> <p><span style="font-weight: 400;">[Trail Variance - Price Gap] 2,000 USDT</span></p> <p><span style="font-weight: 400;">[Quantity] 1 BTC</span></p> <p><span style="font-weight: 400;">[Price Type] Last Transaction Price</span></p> <p><span style="font-weight: 400;">In the event where the BTC price keeps increasing to the highest point of 40,000 USDT after the order is placed, and then retraces to 38,000 USDT, reaching the retracement condition (40,000 USDT - 2,000 USDT = 38,000 USDT), the system decides for the user to sell at the market price at 38,000 USDT.</span></p> <p><span style="font-weight: 400;">Case 2 (Buy the dip): The user wants to buy BTC and the last transaction price is currently 40,000 USDT.</span></p> <p><span style="font-weight: 400;">Then one may set the parameters as follows.</span></p> <p><span style="font-weight: 400;">[Trail Variance - Ratio] 5%</span></p> <p><span style="font-weight: 400;">[Activation Price] 30,000 USDT</span></p> <p><span style="font-weight: 400;">[Quantity] 1 BTC</span></p> <p><span style="font-weight: 400;">[Price Type] Last Transaction Price</span></p> <p><span style="font-weight: 400;">In the event where the BTC price keeps falling to 30,000 USDT after the order is placed, the trailing is activated, it then falls all the way to 20,000 USDT and bounces back to 20,000 USDT * (1 + 5%) = 21,000 USDT, reaching the retracement condition (5%), the system decides for  the user to buy at the market price at 21,000 USDT. </span></p> <p> </p> <p><strong>Post Only</strong></p> <p><span style="font-weight: 400;">Post-only orders will not be filled in the market immediately, which ensures that the user is always a maker and enjoys the yield of the trading fee as a liquidity provider; at the same time, if the order is filled with an existing order, then the order will be canceled immediately.</span></p> <p> </p> <p><strong>TP/SL</strong></p> <p><span style="font-weight: 400;">TP/SL refers to the pre-set trigger price (take profit price or stop loss price) and trigger price type. When the last price of the specified trigger price type reaches the pre-set trigger price, the system will place a close market order according to the pre-set quantity in order to take profit or stop loss. Currently, there are two ways to place a stop loss order:</span></p> <ol> <li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Set TP/SL when opening a position: This means to set TP/SL in advance for a position that is about to be opened. When the user places an order to open a position, they can click to set a TP/SL order at the same time. When the open position order is filled (partially or fully), the system will immediately place a TP/SL order with the trigger price and trigger price type pre-set by the user. (This can be viewed in open orders under TP/SL.)</span></li> </ol> <p> </p> <ol> <li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Set TP/SL when holding a position: Users can set a TP/SL order for a specified position when holding a position. After the setting is complete, when the last price of the specified trigger price type meets the trigger condition, the system will place a close market order according to the quantity set in advance.</span></li> </ol>

style="font-weight:400">In a highly volatile trading environment, a trader holding a large position with high leverage will likely incur the significant risk of deficit loss. If the insurance fund is depleted, the auto-deleveraging system may be triggered, creating additional risk for other traders. Therefore, the risk limit mechanism is applied to all trading accounts in MEXC. The system uses a tiered margin model for risk control and the leverage multiple depends on the size of the position. The larger the position, the lower the available leverage multiple. Users may adjust the leverage multiple themselves. The initial margin rate is calculated based on the leverage multiple adjusted by the user.</span></p>  <ul><li style="font-weight:400"><strong>Position Limit, Maximum Leverage, and Initial margin rate</strong></li></ul>  <p><span style="font-weight:400">Before opening a position, users are required to adjust the leverage multiple. If the user did not adjust the leverage, the MEXC default leverage multiple of 20x will be applied. However, users can still adjust the multiple. The leverage multiple determines the position limit, where the higher the leverage multiple, the lower the position limit.</span></p>  <p><span style="font-weight:400">When the user adjusts the leverage multiple, an alert regarding the position limit will pop out as shown below:</span></p>  <h1 class="wysiwyg-text-align-center"><span style="font-weight:400"> <img src="https://mexc-rainbown-activityimages.s3.ap-northeast-1.amazonaws.com/banner/F20230428231353592a42TwZ7A3A4SOf.png" alt="3en.png" width="231" /></span></h1>  <ul><li style="font-weight:400"><strong>Maintenance margin rate</strong></li></ul>  <p><span style="font-weight:400">The maintenance margin rate is not calculated based on the user&#39;s adjusted leverage multiple, but the user&#39;s position size, which means that the maintenance margin rate is not affected by the leverage multiple. The system divides the position amount into several tiers according to the basic risk limit and incremental amount of the futures. Different maintenance margin rates are applied to different tiers, where the larger the position amount, the higher the maintenance margin rate. (For risk limit details of each futures, kindly check </span><strong>Risk Limit</strong><span style="font-weight:400"> under </span><strong>Futures Information</strong><span style="font-weight:400">.)</span></p>  <p><span style="font-weight:400">The liquidation price is affected directly by the maintenance margin. Therefore, to avoid liquidation, we strongly recommend users to close their positions before the margin balance drops to the maintenance margin level.</span></p>  <p><span style="font-weight:400">Please note that under abnormal price fluctuations and volatile market conditions, the system will take additional measures to maintain market stability, including but not limited to:</span></p>  <ul><li style="font-weight:400"><span style="font-weight:400">Adjustment of maximum leverage</span></li><li style="font-weight:400"><span style="font-weight:400">Adjustment of position limits for different tiers</span></li><li

0.5%.</span></p>  <p><span style="font-weight:400">Later on, as the price of BTCUSDT perpetual futures rises, User A continues to buy in 40,000 cont., meaning the user is holding 120,000 cont. now. This corresponds to the 2nd tier of risk limit (no. of open positions: 100,000 - 200,000 cont.). Hence the position maintenance margin rate is 1%.</span></p>  <p><span style="font-weight:400">At this point, if the user’s position is under liquidation risk, liquidation will be triggered. As it is in the higher tier, liquidation by tier will be activated. Position of 20,000 cont. will be liquidated first, lowering the no. of open positions to 100,000 cont. This will lower the risk limit from the 2nd tier to 1st tier and the maintenance margin rate from 1% to 0.5%. The condition of the remaining positions will be monitored and the remaining positions will be liquidated if they remain under liquidation risk. If not, the positions will be kept.</span></p>
