ETH perp cost slope: size impact on the deepest pair

As of August 3, 2026, gains.trade leads ETH cost slope ($1M / $1k) at 1.000x (p50, 24h window), measured across 8 providers.

ETH-PERP is the deepest pair on every venue in the cohort. On orderbook venues the $1M tier is usually filled because ETH books carry several million USD of visible depth on the ask side. The slope is therefore computable for most venues on ETH, and the spread between the oracle-priced 1.00 and the orderbook venues reveals the raw cost of depth-limited execution. Gains and GMX always read 1.00 because their protocol charges a flat open fee regardless of notional; there is no book to walk for ETH on those venues.
