What data exists for each NWSL market?

How much does a typical NWSL market trade?
Average traded volume is $300 per market, $177.4K 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.
