What Is a Futures Contract?
A futures contract is a binding agreement between two parties to buy or sell an asset at a specific price on a future date. In crypto, futures allow traders to speculate on price movements with leverage without owning the underlying asset, and enable hedging against price risk.
How Futures Work
Quarterly futures expire on set dates (e.g., March, June, September, December). At expiry, positions are settled — either physically (asset delivery) or cash-settled (profit/loss paid in stablecoins).
Perpetual futures have no expiry and use funding rates to stay anchored to spot price. They are by far the most traded crypto derivatives product.
Futures require posting margin (collateral) and allow leverage, meaning you control more notional value than your capital. 10x leverage means $1,000 in margin controls a $10,000 position.
Why It Matters for Traders
Futures provide leverage, short-selling capability, and hedging tools that spot markets lack. They also generate valuable data — open interest, liquidation levels, funding rates, and basis — that give insight into market positioning and potential price moves.
How It Works on CEX Perps
On centralized perpetual futures venues, futures contract shows up in the position panel, the funding timer, or the liquidation engine rather than as a separate product. Traders usually check it next to mark price, margin mode, and open interest so they do not size a trade from last price alone.
Example numbers only (not a live quote): if you hold a $10,000 notional long with 5x leverage, your initial margin is about $2,000. A move against you of roughly 20% of that notional can push the position near maintenance margin depending on the venue formula. Always read the venue's own liquidation rule before you size.
Formula and Worked Example
Use this only as a labeled example. It is not a live market print.
- Notional = coin size × mark price.
- Initial margin ≈ notional ÷ leverage.
- Distance to liquidation depends on maintenance margin, fees, and whether you use cross or isolated margin.
Example: 0.1 BTC long, mark $60,000, leverage 10x → notional $6,000, initial margin about $600. If maintenance margin is near 0.5% of notional, a modest adverse move can close the trade even when your thesis is still intact.
Common Mistakes
- Treating a single print of futures contract as a trade signal without checking funding, open interest, and your liquidation price.
- Mixing venue conventions (coin-margined vs USDT-margined, cross vs isolated) and reading the wrong mark.
- Copying example numbers from a glossary into live size without checking the current book depth and fee schedule.
- Ignoring related terms that change the meaning of the print on a given day.
