Pricing

Notes and limits

Kalshi returns candles only for periods where the market existed. Short-lived markets return short series.
1-minute candles over long windows are large. Cap with Max candles or narrow the dates.
This Actor never places orders and needs no Kalshi credentials.

Kalshi Markets Scraper: current prices, volume, open interest and order books for every market.
