What data exists for each Belgium Pro League market?

Average traded volume is $8.3K per market, $233.2K across the series.
Can I backtest strategies on Belgium Pro League?
Yes. Pass the slug "bel1-games" 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.
