# Combo Legs 🌱

> Polymarket Combos v3 legs: one row per combo condition and ordered leg.

The `polygon.predictions.combo_legs` table lists every leg of a Polymarket Combos (v3) parlay. One row is one (combo, ordered leg). ComboExchange fills are `contract_version = 'v3'` on `trades_enriched`.

`combo_condition_id` is the combo id on those fills. `market_token_id` is the outcome token on `markets.token_id`. Each `markets.condition_id` has two token rows. `leg_question_id` is set on negrisk (`02`) legs only.
