What is Predexon?
A terminal or wallet tracker can combine market discovery, prices, books and historical activity with eligible live channels. Binance reference data is also documented alongside the prediction-venue integrations. Plan quotas distinguish standard historical endpoints from premium requests, while streaming has its own subscription and item limits.
Bulk tick history follows a different purchase flow: choose a venue, market and time slice, request a free quote, then inspect the size and price before downloading compressed Parquet through signed URLs. Trade history and recorded order-book history start at different points. Neither a downloaded L2 book nor an activity feed automatically establishes a hypothetical queue position or a confirmed transaction.
