tag_metrics_update
Volume on Polymarket vs. Struct. Polymarket’s UI reports “volume” as notional (the count of shares or contracts traded), which corresponds to shares_volume in Struct payloads. usd_volume is the dollar value of those trades. Use shares_volume to match figures shown on Polymarket and usd_volume for true USD throughput.
