How much does a typical MLS 2025 market trade?

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. "total") to backtest one type at a time.
