CoinGlass review

The dashboard traders actually check

Open interest, funding rates and liquidation activity aggregated across the major derivatives venues, mostly free, in one place. For reading positioning before a volatile session, it is the fastest available answer and the reason the site appears in so many screenshots.

Everything here is second-hand

The figures are relayed from exchange APIs, so their accuracy is the exchanges' accuracy — and self-reported derivatives data has a long history of being generous. Liquidation totals are modelled estimates derived from those feeds rather than observed settlements, which the site states. Use the direction and the shape, not the decimal places.

What it is good for

Spotting crowded positioning, comparing funding across venues before choosing where to carry a trade, and seeing where liquidation clusters sit. Most core data is free, with paid tiers adding history depth and alerting at published prices.

How professionals use it

To answer one question quickly: which side is crowded. Funding persistently positive with rising open interest means longs are paying to stay long, and that is a condition, not a signal — it tells you what a sharp move would liquidate, not when.

Its blind spot

Everything depends on what exchanges choose to report through their APIs, and derivatives self-reporting has a long history of generosity. Treat cross-venue totals as indicative rather than exact.
