Prices normalized to YES side (NO prices converted as 1 - price). **Free & Unlimited.** This endpoint does not count toward your monthly usage limits on any plan. ### Intervals | Interval | Value | Max Range | | ---------- | ------------- | ------------------------------------------------ | | Auto | `0` (default) | Picks the best interval based on your time range | | 1 minute | `1` | 7 days | | 5 minutes | `5` | 14 days | | 15 minutes | `15` | 30 days | | 1 hour | `60` | 90 days | | 1 day | `1440` | Unlimited (all-time) | The response includes `first_trade_ts` and `last_trade_ts` - the Unix timestamps of the first and last trades in the market, useful for determining the full available data range. It also echoes back the resolved `interval` (in minutes) and `interval_seconds` (bucket width), so you know which bucket size was picked when requesting `interval=0`. ## OpenAPI ````yaml GET /v2/polymarket/candlesticks/{condition_id} openapi: 3.1.0 info: title: Predexon API description: Prediction market data aggregation and matching API version: 2.0.0 servers: - url: https://api.predexon.com security: - apiKey: [] paths: /v2/polymarket/candlesticks/{condition_id}: get: tags: - polymarket summary: Get Candlesticks description: >- Fetch historical candlestick data for a market.
