Measuring Stock Perpetual Liquidity with Order-Book Depth and Slippage
Summary
This article explains how institutional traders can assess liquidity in tokenized stock perpetual futures. It distinguishes headline volume and a narrow bid–ask spread from executable depth at several distances from the mid-price. Depth at 5, 10, and 50 basis points, along with slippage at different order sizes, is presented as a way to estimate how much a large order may move through the book. The discussion also recommends examining liquidity across trading hours, weekends, news, and volatile conditions.
The article supports its venue comparison with Bitget monitoring data for July 5–11, 2026, reporting aggregate depth and rankings across 32 contracts, and with Block Scholes research on NVDA and SPY markets, including six-figure order scenarios. These figures are the article’s reported evidence, not an independent verification of execution quality. Order-book snapshots can change, displayed depth may not remain available, and historical measurements do not guarantee future fills. The piece is also promotional and focuses heavily on one venue, so its comparisons should be treated with that source limitation in mind.
Key ideas
- Order-book depth near the mid-price helps estimate executable size beyond the best bid and ask.
- Depth at wider price bands shows how much liquidity may remain as larger orders consume the book.
- Spread, trading volume, open interest, and depth measure different aspects of market conditions.
- Slippage should be compared across order sizes and market conditions to assess execution capacity.
- Historical venue rankings and displayed depth cannot guarantee future execution quality.
