Constituent divergence history, last 30 days
No constituent divergence recorded for SAGA in the last 30 days.
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.
