How far back does Polymarket historical data go?

Onchain fills data covers the full history (3+ years) of Polymarket settlements on the Polygon blockchain from market inception.

What is tick-level prediction market data?

Tick-level data means every individual event is recorded: every trade execution, every order book update, and every quote change. This is the highest resolution of market data available, as opposed to aggregated candle/OHLCV data that summarizes activity into time intervals. Tick-level data is essential for accurate backtesting, market microstructure research, and understanding information flow through prediction markets.

Can I backtest prediction market strategies with this data?

Yes. Telonex data is designed for backtesting with tick-level trades, full order book depth, quotes, and onchain fills that allow you to reconstruct historical market states at any point in time and accurately simulate trading strategies without sampling or interval aggregation.
