bps (basis points) — 1 bps = 0.01 % of the mid price. A spread of 5 bps on $10k is $5 round-trip ($2.50 one-way). Half-spread cost assumes you cross the book once at $10k notional. Top-20 depth (total) is the mid-side total USD notional across the top 20 bid+ask levels of the book — ((bid_avg_per_level + ask_avg_per_level) / 2) × 20. Upstream exposes the per-level averages, so we scale by 20 to recover the actual depth. The screener's Min Top-20 total $ bound is in TOTAL notional, not per-level. ⚠ on a venue label means its 24h venue-wide turnover is below 1 % of the leader's, so its tight quotes may not reflect real execution.
Screener universe — by default the screener hides peg/stable pairs: pairs where both base and counter are stablecoins (USDC/USDT, USD1/USDT, FDUSD/USDT) and wrap-pegs that track 1:1 to an underlying (WBTC/BTC, stETH/ETH, weETH/ETH). These have mechanically deep books with no directional information, so they crowd out actual trading pairs in any tight/deep ranking. Toggle Include peg/stable pairs brings them back. The Quote filter splits the universe into USD-stablecoin-quoted (USDT, USDC, USDE, FDUSD…), coin-margined (BTC, ETH, SOL, BNB, XRP-quoted), or All (also EUR, JPY, TRY pairs).
