Understanding futures trading requires familiarity with a set of key terms that govern how contracts are priced, managed, and settled. Whether you're new to digital asset derivatives or refining your strategy, this guide breaks down essential futures terminology in clear, actionable language—optimized for both learning and real-world application.
Core Concepts in Futures Trading
Before diving into advanced strategies, it's crucial to grasp the foundational elements that shape every futures position.
Index Price
The index price represents the average spot price of a digital asset across multiple major global exchanges. This benchmark helps prevent price manipulation on any single exchange and ensures fair valuation across the platform.
Underlying Asset
This is the digital asset that backs the futures or perpetual contract—such as Bitcoin (BTC) or Ethereum (ETH). All price movements, settlements, and payouts are based on the performance of this asset.
Market Price
Also known as the last traded price, this reflects the most recent transaction executed on the exchange. It provides real-time insight into current market sentiment and liquidity.

Understanding Fair Value: The Role of Mark Price
Mark Price (Fair Value / MTM)
Mark price is a calculated "fair value" used to reflect true market conditions by factoring in funding rates, index prices, and recent trade data. Unlike the volatile market price, mark price smooths out short-term fluctuations to provide stability.
Why Mark Price Matters:
- Calculates unrealized profit and loss (P&L) accurately.
- Determines liquidation risk by comparing your position against this stabilized value.
- Prevents market manipulation, especially during periods of low liquidity or sudden price spikes.
Spot Price
Similar to index price, the spot price refers to the current market value of an asset for immediate delivery. In futures trading, it’s often averaged across top exchanges to ensure accuracy and fairness.
Notional Value
This is the total value of your open position, calculated using the formula:
Notional Value = Mark Price × Number of Contracts × Contract Multiplier
Example:
If you hold 100 BTC contracts at a mark price of $40,200, and each contract has a multiplier of 0.001 BTC:
= $40,200 × 100 × 0.001 = **$4,020 notional value**
This figure is vital for assessing exposure and managing risk across your portfolio.

Contract Multiplier
Each futures contract represents a fixed amount of the underlying asset. On most platforms, including BTSE, one contract equals 0.001 units of the asset (e.g., 0.001 BTC per contract).
Number of Contracts
This indicates how many individual contracts you’ve bought or sold. It directly affects your position size and potential gains or losses.
Contract Type
- Long Position (Buy/Go Long): You buy first, aiming to sell later at a higher price.
Example: Holding 100 BTC contracts long means you profit if Bitcoin’s price rises. - Short Position (Sell/Go Short): You sell first, intending to buy back later at a lower price.
Example: Selling 100 BTC contracts implies you expect a decline in Bitcoin’s value.
Entry Price
The initial price at which you open your position—either by buying (long) or selling (short). This becomes the baseline for calculating your profit or loss.
Leverage and Risk Control
Leverage
Leverage allows traders to control a larger position with a smaller amount of capital. It’s expressed as a ratio:
- 100x leverage = $1 controls $100 worth of assets (only 1% margin required)
- 1x leverage = Full collateral; no borrowed funds involved
While high leverage can amplify returns, it also increases the risk of liquidation—making risk management critical.

Risk Limits
These are built-in mechanisms designed to reduce the likelihood of large-scale liquidations. Higher leverage often comes with stricter risk limits, such as reduced position sizes or tighter margin requirements.
Margin Mechanics
Initial Margin
The minimum amount of collateral required to open a leveraged position. This varies depending on leverage level and market volatility.
Maintenance Margin
The minimum equity needed to keep a position open. If your account balance falls below this threshold due to losses, you risk being liquidated.
Unified Wallet
A flexible margin system that allows multiple cryptocurrencies (e.g., BTC, ETH, USDT) to be used as collateral within a single account.
Note: Up to 10% of the digital asset’s value may be held as collateral, depending on platform rules.
Isolated Wallet
Limits margin to a single cryptocurrency type per contract. Offers more control but less flexibility than a unified wallet.
Note: Similarly, 10% of asset value is typically reserved as collateral.
Liquidation and Safety Mechanisms
Liquidation Process
When losses deplete your margin below maintenance levels, the system automatically intervenes:
- Your position and associated collateral are taken over by the system.
- Forced buy/sell orders execute between liquidation price and bankruptcy price.
- The exchange’s insurance fund may cover part of the loss.
- If unresolved, Auto-Deleveraging (ADL) closes positions incrementally.
Liquidation Price
The market price at which your position is forcibly closed due to insufficient margin.
Bankruptcy Price
The theoretical price point where your entire margin would be wiped out—your account balance reaches zero.
Auto-Deleveraging (ADL)
A last-resort mechanism used when liquidation fails to close losing positions quickly enough. ADL matches losing traders with profitable counterparties to settle obligations fairly.
ADL Indicator
Displays your likelihood of being auto-deleveraged during extreme market events. High ADL risk suggests crowded positions and limited exit liquidity.
Profit and Loss Tracking
Unrealized P&L
Gains or losses on open positions that haven’t been settled yet. These fluctuate with market movement and are calculated using mark price.
Realized P&L
Actual profits or losses locked in once you close a position. This impacts your available balance and overall trading performance.
Additional Key Terms
Market Maker
A trader or algorithm that provides continuous buy and sell quotes to enhance market liquidity. Market makers earn small spreads in return for reducing slippage.
Funding Rate
Periodic payments exchanged between long and short positions in perpetual contracts. Designed to keep futures prices aligned with spot markets.
- If funding rate is positive, longs pay shorts.
- If negative, shorts pay longs.

Basis / Basis Spread
The difference between the entry price of a futures contract and the spot price at expiration. Traders analyze basis trends to assess market sentiment and arbitrage opportunities.
Bid vs Ask Price
- Bid Price: Highest price a buyer is willing to pay.
- Ask Price: Lowest price a seller is willing to accept.
The gap between them—the bid-ask spread—reflects market depth and liquidity.
Frequently Asked Questions
Q: What’s the difference between mark price and market price?
A: Market price is the latest traded price, while mark price is a smoothed, fair-value estimate used to calculate P&L and prevent manipulation.
Q: How can I avoid liquidation?
A: Use conservative leverage, monitor your margin ratio, set stop-losses, and avoid overextending during volatile periods.
Q: Can I use multiple coins as margin?
A: Yes—via a unified wallet system that supports multi-collateral deposits like BTC, ETH, and stablecoins.
Q: What happens when ADL triggers?
A: Your position may be partially or fully closed based on counterparty availability and system priority, especially during flash crashes.
Q: Why do funding rates exist?
A: They align perpetual contract prices with real-world spot values, discouraging prolonged deviations.
Q: How is notional value used in risk management?
A: It helps quantify total exposure across positions, enabling better portfolio diversification and margin planning.
Final Thoughts
