Realtime feed: every market now also at source

Every self-serve realtime market is now also sold at the endpoint where its venue is captured: Binance USDT-M, Binance Spot and OKX at Tokyo, Coinbase Spot at Ashburn, Kalshi at Ohio, Polymarket at London. The same feed, the same protocol and the same port as over a line — one API key for every market and endpoint.

At source, the normalized feed is handed over at the site where the venue is captured: no dedicated line, so there is no line latency to quote. A day at source costs €35 per instrument-day or €69 per market-day (Kalshi and Polymarket by the market-day only, as whole markets); the duration prices for longer runs apply the same way.

The dedicated lines to our other endpoints stay exactly as they are.
