ASTR perp index risk
Each exchange prices ASTR perp liquidations from a mark price built on an index: a weighted basket of spot prices. This page shows each index's composition and an estimate of how much resting spot liquidity backs it.
Index depth is a static-book estimate for the index, not the mark. Static-book estimates from public exchange data. Not a real cost to move any price, not a mark-price forecast, and not trading advice. Methodology and limitations · Constituent changes · All perps

Index, not mark. Index depth is a static-book estimate of resting spot liquidity between the index and the stated move, after the exchange's guard. Liquidations use the mark price, which also follows the perp's own price and basis. Static-book estimates from public exchange data. Not a real cost to move any price, not a mark-price forecast, and not trading advice.
Method. Constituents and weights come from each exchange's public index API, refreshed hourly. Spot order books are sampled every 5 minutes. Sources we cannot read are held fixed, so the figure is neither an upper nor a lower bound. See how mark and index prices work and the constituent change log.
ASTR index risk FAQ
What does this page show?
For each ASTR perpetual on Binance, OKX, Bybit and Bitget: the spot sources the exchange uses for its index and their weights, how far each source's price currently sits from the median of the others (observed), the exchange's published outlier guard, and a static-book estimate of resting spot liquidity between the index and +/-2% and +/-5%.
Is index depth the amount needed to move the mark price?
No. Liquidations use the mark price, which also depends on the perp's own price and basis. Index depth is a static-book estimate for the index only: real books refill and arbitrage closes gaps, so it is neither an upper nor a lower bound on any real-world figure.
What do the coverage states mean?
OK: at least 80% of index weight comes from order books we read, books under 15 minutes old and constituents under 2 hours old. Partial: 50-80% modelled, the rest held fixed. Stale: the last estimate is older than that and is shown greyed. Insufficient: composition only, no depth or ratio.
Why is the sensitivity marked uncalibrated?
It multiplies the static-book figure by 0.5x, 1x and 2x to show how much the estimate depends on book refill. The multipliers are not fitted to observed events yet, so treat them as a range of assumptions, not a measurement.
