How many WTA markets are in the archive?

22,779 markets from June 19, 2026 through September 21, 2026, of which 22,666 have resolved and 113 are active.

What data exists for each WTA market?

Full depth L2 order book snapshots at regular intervals, individual trades, OHLC candles, and the resolution outcome, with the full price change stream at millisecond resolution on the most actively traded markets in the series. All of it is queryable by the series slug "wta" through the API and Python SDK, or downloadable as Parquet.

How much does a typical WTA market trade?

Average traded volume is $7.0K per market, $54.6M across the series.

Can I backtest strategies on WTA?

Yes. Pass the slug "wta" to client.backtest() in the Python SDK. Execution mode replays order books against real historical depth; Alpha mode, one bar per market, covers every market in the series and suits its longer horizons. This series mixes several bet types, so pass subtype= (e.g. "moneyline") to backtest one type at a time.
