/v1/cefi/market

Server

Message sent from server with the exchange's own view of a subscribed price index after each one-second bar applies: the bar, the feed state, and the settlement value on the bar that closes a settlement window. An up/down outcome market opens at the settlement value of the window ending at its open time (its strike) and resolves YES when the settlement value of the window ending at its expiry is strictly above it, so a client can check a verdict from this stream rather than trust it. Items are observable ids as strings; an outcome instrument's terms.resolver_id names its observable.

Code Sample

const socket = new WebSocket("wss://api.truemarkets.co/v1/cefi/market");

socket.addEventListener("message", (event) => {
  console.log(event.data);
});
