Measuring Liquidity in 24/7 Stock Perpetual Futures
Summary
The guide explains liquidity for USDT-margined perpetual futures linked to stocks, ETFs, and indices. It defines bid-ask spread and order-book depth as practical measures of execution conditions, then explains depth within 5, 10, and 50 basis points of the current price. Tighter spreads and deeper books can reduce price impact, but a large market order in a thin book may fill across multiple price levels. It also describes 24/7 trading, long and short exposure, funding, margin modes, leverage, and the distinction between a derivative position and ownership of shares. The article notes that API access can support automated trading and execution.
The operational lesson is to inspect the live spread, depth, volume, funding, and liquidation terms for each contract. Liquidity can vary by contract and may weaken outside regular stock-market hours, on weekends, around earnings, or during volatility. The article’s rankings and volume figures are platform claims rather than a neutral comparative study, and it provides no independent methodology or sample data for verifying them. Deep displayed liquidity does not eliminate slippage, funding costs, gaps, or liquidation risk.
Key ideas
- Bid-ask spreads and order-book depth indicate how readily a contract may be traded near its current price.
- Depth measured at 5, 10, and 50 basis points describes liquidity across progressively wider price ranges.
- Thin books can cause market orders to execute at several prices and increase slippage.
- Stock-linked perpetual futures allow long or short exposure without conferring share ownership.
- Liquidity can change with trading hours and volatility, so live market conditions and liquidation terms matter.
