BTC/ETH/SOL/XRP Historical 5 & 15-Min Up/Down Data
Would anyone be interested in second-level (1s frequency) market data for backtesting or research purposes?
I have up/down market data (best ask price) for BTC, ETH, SOL, and XRP markets, scraped from the Gamma API (by auto-slug mapping to the right 5/15mins market). This dataset is at 1-second intervals (while Polymarket API only provides 1-minute granularity last I checked).
Coverage:
5-minute intervals: 20 Feb 2026 to 4 May 2026, 15:42:34
15-minute intervals: 7 Jan 2026 to 4 May 2026
I stopped updating due to work commitments and some (lack of) trading success, but I'm happy to share or discuss the dataset if anyone's interested.
Curious what else would you use this kind of data for?
Sample as attached.
