Terms	Definition
Available Margin	The portion of your total equity that can be used to open new positions or cover fees and losses.
Cross Margin	A margin mode where all available funds in your account can serve as margin for a single position, helping prevent premature liquidation of individual positions.
Earn	Flexible savings feature. Deposit idle assets from your pot account into the savings fund pool and earn daily interest based on a dynamic annualized percentage rate. No lock-up period, deposit and withdraw anytime.
Funding Rate	A periodic fee paid to balance long and short positions. When the market is imbalanced, the dominant side pays the funding rate to the other to encourage market equilibrium.
Fund Password	A separate password that protects sensitive asset operations. Withdrawals, vault withdrawals, and other sensitive operations require entering the Fund Password for secondary confirmation. Rules: 8–16 characters, must include upper and lower case letters, digits, and special characters.
Gap	Refers to a price range on a chart of an asset (such as a stock, futures contract, or cryptocurrency) where no trading occurred during a given trading session or between continuous market periods. This phenomenon typically arises when major news or events cause a sudden imbalance between supply and demand, resulting in a visible blank space on the price chart.
Impact Cost	A measure of how your order size affects market liquidity. Larger orders mean higher impact cost. The system shows you an estimate before you submit your trades.
Liquidations	When your margin falls below the Maintenance Margin Ratio (MMR), the system automatically closes your position to prevent further losses. Our liquidation process uses the Mark Price, not manipulable last traded prices.
Liquidity	The ease of buying or selling an asset without significantly affecting its price. MC Markets provides continuous liquidity through its dynamic liquidity model for efficient trade execution.
Margin	The funds required to open and maintain positions. It acts as collateral, allowing you to control a larger position than your account balance.
Margin Ratio	A metric measuring position health, used to determine proximity to liquidation thresholds.
Mark Price	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.
Mid-Price Input	A smart limit order function generated based on the market "mid-price" (the average of the best bid and ask prices). Upon clicking, the system automatically inputs the limit order price based on the real-time mid-price, which facilitates manual price adjustment while ensuring both fair pricing and execution efficiency.
MMR (Maintenance Margin Ratio)	The minimum margin ratio required to maintain a position. Falling below this ratio triggers forced liquidation to protect your account and the platform from further losses.
Position Value	The total value of your position in USD. For example, buying 1 BTC at $50,000 gives a nominal value of $50,000.
Premium Account	Charges a fee per instrument in exchange for better execution conditions. Better suited for high-volume, high-frequency, or execution-sensitive traders.
Oracle	External data providers supplying independent, verified spot reference prices. MC Markets uses these for calibration and risk comparisons.
PnL (Profit and Loss)	Your trading profits or losses. Unrealized PnL is the floating profit/loss on open positions; Realized PnL is the net profit/loss from closed trades.
Price Penetration	A technical analysis concept describing a price movement that breaks through a specific level, such as support, resistance, a trendline, or a moving average. Such a movement suggests that buying or selling pressure has temporarily overcome the prevailing market consensus, potentially signaling a trend reversal, continuation, or merely a false breakout that traders should watch carefully.
Proof of Reserves	MC Markets publicly discloses its on-chain reserve data, maintaining a reserve ratio of 100% or above at all times to ensure full coverage of user assets. Users can view the latest reserve ratio, total user asset value, and total platform reserve value on the [Proof of Reserves] page.
Standard Account	Commission-free across all instruments. Suited for everyday trading needs.
Swap	Instant asset conversion within your account, powered by the platform’s internal pricing engine. No blockchain confirmation needed.
Skew	A measure of imbalance between long and short positions on the platform. High skew indicates one-sided markets, influencing funding rates.
Tick	The smallest price increment for an asset. For example, BTCUSD typically ticks at $1.0, while ETHUSD at $0.1.
Total Account Value	The net value of your entire account, including all perpetual, spot, unrealized & realized profit and losses, and the total value of your vault. It's a comprehensive indicator of account health.
Vault	Allows you to deposit funds into an automated strategy for passive returns. Vault assets are ring-fenced from trading risk through independent hedging.
