Term	Meaning
fill	One `OrderFilled` event: one order’s part in a match, seen from that order owner’s side. A match yields one taker fill and one fill per maker order, so summing every fill counts matched volume twice.
maker / taker	The taker’s order crossed the book; makers’ orders rested on it. `role` on a trade, `isTaker` on a fill row.
split	Lock collateral and mint a full set: $1 gives 1 Yes and 1 No.
merge	The reverse: burn a full set, get the collateral back.
redeem	After resolution, burn shares for their payout.
neg-risk	Polymarket’s multi-outcome events (one winner among many questions). Each question is its own Yes/No market with its own conditionId.
convert	Neg-risk only: give up No on some questions of an event, receive Yes on the others plus collateral.
combo	Polymarket’s combinatorial position (a parlay): 1 to 50 legs, each one side of a binary market. Codex books each combo as a two-outcome market whose conditionId is its Yes token. An open combo is carried at cost (`carriedAtCost: true`): no fill prices it.
v2 leg	An outcome of a regular market held through Polymarket’s protocol-v2 modules, usable in combos. Booked as a position of its regular market and marked `v2Leg`.
exchange	`ctf-v1`, `negrisk-v1` (before the April 28, 2026 cutover), `ctf-v2`, `negrisk-v2`, `combos-v3`.
settled PnL	Realized PnL plus, for a resolved market, the payout of shares still held minus their cost. What the leaderboard ranks.
