In trading, Perpetual futures (perps) is a leveraged derivative contract with no expiry date, available on exchanges like Binance, Bybit, OKX, and Hyperliquid, that uses periodic funding rate payments every 8 hours to keep its price anchored to the underlying spot market. This glossary entry explains why perpetual futures (perps) matters, how traders use it, and how to track it with evidence instead of vibes.
Quick definition
Perpetual futures (perps): a leveraged derivative contract with no expiry date, available on exchanges like Binance, Bybit, OKX, and Hyperliquid, that uses periodic funding rate payments every 8 hours to keep its price anchored to the underlying spot market.
Perpetual futures (perps) is a leveraged derivative contract with no expiry date, available on exchanges like Binance, Bybit, OKX, and Hyperliquid, that uses periodic funding rate payments every 8 hours to keep its price anchored to the underlying spot market. The practical version is: can you define it as a field you can log and audit later?
Most trading terms become confusing when they are used as vibes instead of variables. Your goal is a definition that helps you decide size, stop, entry timing, or whether to skip the trade.
Traders sometimes confuse Perpetual futures (perps) with margin trading. Treat them as separate variables in your journal so your reviews stay honest.
Perps are the dominant instrument in crypto trading — over 75% of crypto derivatives volume is perpetual futures. They let you go long or short with leverage (typically 1-125× on Binance, 1-100× on Bybit), but they introduce three costs that spot trading does not have: funding payments, liquidation risk, and mark-price-based margin calculations. A trader who goes long BTC-USDT perp at $67,000 with 10× leverage pays taker fees (~0.055% on Bybit), funding every 8 hours (variable, often +0.01-0.04% when longs dominate), and faces liquidation if the position drops ~9.5%. That same directional bet on spot has no funding, no liquidation, and lower fees — but no leverage. Understanding when perps are worth the cost is the core skill.
If Perpetual futures (perps) never changes your decision, it is just jargon. The term earns its place when it improves your process consistency under real market pressure.
A useful mental model: plan first (risk and invalidation), execute second (order type and fills), review last (tags and metrics).
Use it to make one decision pre-trade. Example decisions: where the stop goes, whether to take partials, how to scale size, or whether conditions are too thin to trade.
Write the rule in one sentence, then run it consistently for a week. Consistency matters because it creates comparable data for review.
If the rule fails, adjust slowly. Do not rewrite the whole system after one bad session.
For every perps trade in Tiltless, log: (1) leverage used, (2) funding rate at entry and cumulative funding paid/received, (3) liquidation price and buffer as a multiple of the asset's ADR, (4) margin mode (isolated vs cross). Review monthly: compare net PnL (after funding + fees) versus gross price-move PnL. If funding consistently erodes more than 15% of your gross gains, either shorten hold times, trade during negative funding windows, or switch to spot for longer-duration directional trades.
Use tags so you can slice results by regime and behavior state. The same term behaves differently when volatility changes or when you are fatigued.
Your review question should be binary: did this variable improve outcomes or reduce rule breaks? If not, simplify.
You long ETH-USDT perp on Binance at $3,400 with 5× leverage ($17,000 notional, $3,400 margin). Funding is +0.03% per 8-hour window. You hold for 4 days (12 intervals). Funding cost = $17,000 × 0.03% × 12 = $61.20. Taker fee entry = $17,000 × 0.055% = $9.35, maker fee exit = $17,000 × 0.02% = $3.40. ETH moves to $3,500: gross profit = $500. Net profit after costs = $500 − $61.20 − $9.35 − $3.40 = $426.05. Funding and fees consumed 14.8% of your gross gain. On spot with the same $3,400 capital, you would have made $100 gross (no leverage) with only ~$1.70 in fees — a smaller absolute gain but 99.5% cost efficiency.
The point of an example is not to predict price. It is to show what you would log before the trade and what you would audit after the trade.
Trading perps as if they are leveraged spot — holding positions through multiple funding windows without tracking cumulative cost, and ignoring the liquidation price until the exchange sends a warning. The perps-specific risks (funding drag, liquidation cascades from correlated OI buildup, mark-price divergence during wicks) require separate journal tracking that spot trading does not.
The fastest way to improve perpetual futures (perps) is to remove one failure mode at a time. If you try to fix everything, you will fix nothing.
Perpetual futures (perps) interacts with exchange mechanics: margin mode, mark/index rules, and funding/fees. If you ignore those, your backtest brain will lie to you.
In derivatives, survivability is first. Treat liquidation and forced exits as unacceptable outcomes, not as 'just a bigger stop'.
Your journal should separate: price-move PnL, fees, funding, and execution quality. Otherwise you can't tell what actually caused the outcome.
Perpetual futures (perps) is a leveraged derivative contract with no expiry date, available on exchanges like Binance, Bybit, OKX, and Hyperliquid, that uses periodic funding rate payments every 8 hours to keep its price anchored to the underlying spot market. In practice, it matters when it changes a concrete decision like size, stop placement, or whether you skip a trade.
They are related but not identical. In your journal, track Perpetual futures (perps) as its own variable and treat margin trading as a separate context factor so you can audit each cleanly.
