NWSL: a Polymarket sports series with markets recurring daily. Marketlens has captured 1,673 markets since July 4, 2026, of which 1,679 resolved, with $1.7M in traded volume. No new markets were collected from August 6, 2026 to October 3, 2026, so windows inside that gap return nothing. Every market's order book is stored in full: periodic L2 snapshots plus every individual price change with a millisecond timestamp, alongside trades, candles, and the final resolution outcome.

Common questions
How many NWSL markets are in the archive?
1,673 markets from July 4, 2026 through now, of which 1,679 have resolved. No new markets were collected from August 6, 2026 to October 3, 2026, so windows inside that gap return nothing.
What data exists for each NWSL market?
Full L2 order book history (snapshots plus every price change at millisecond resolution), individual trades, OHLC candles, and the resolution outcome. All of it is queryable by the series slug "soccer-nwsl" through the API and Python SDK, or downloadable as Parquet.
How much does a typical NWSL market trade?
Average traded volume is $1.2K per market, $1.7M across the series.
Can I backtest strategies on NWSL?
Yes. Pass the slug "soccer-nwsl" to client.backtest() in the Python SDK. Execution mode replays every market's order book tick by tick and fills simulated orders against real historical depth with queue priority, latency, and fee modelling; Alpha mode replays one bar per market for slower signals over long windows. This series mixes several bet types, so pass subtype= (e.g. "moneyline") to backtest one type at a time.
