Depth quote for one crypto perp on ONE named venue
Depth quote for one crypto perp on ONE named venue: best bid/ask, depth per side, and est_slippage_for_size_usd_bps — the cost of filling size_usd here, in BASIS POINTS over the mid, not dollars. On a book deep enough to fill at the touch it equals half the spread and is the same for $1K/$5K/$10K; on a thinner book it grows with size. Equal values across sizes mean the book covers you, not that size_usd was ignored. All venues: /v1/orderbook/multi-venue-slippage. $10K cap per DIS-022.
