What data exists for each MLS 2025 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 "mls-2025" through the API and Python SDK, or downloadable as Parquet.

How much does a typical MLS 2025 market trade?

Average traded volume is $4.2K per market, $3.8M across the series.

Can I backtest strategies on MLS 2025?

Yes. Pass the slug "mls-2025" 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.
