Common questions
How many Serie B markets are in the archive?
60 markets from September 6, 2026 through September 19, 2026, of which 60 have resolved.
What data exists for each Serie B 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 "serie-b" through the API and Python SDK, or downloadable as Parquet.
How much does a typical Serie B market trade?
Average traded volume is $704 per market, $15.5K across the series.
Can I backtest strategies on Serie B?
Yes. Pass the slug "serie-b" 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.
