Gate price feed

Large altcoin exchange. Streamed via the depth channel. Every Gate quote appears in ticker:<SYMBOL> messages with "ex":"gateio".

Only Gate quotes

const ws = new WebSocket("wss://aeonfeed.com/ws?subscribe=ticker:BTCUSDT,ticker:ETHUSDT");
ws.onmessage = (e) => {
  const msg = JSON.parse(e.data);
  if (msg.type !== "ticker" && msg.type !== "snapshot") return;
  const quotes = (msg.data ?? []).filter((q) => q.ex === "gateio");
  for (const q of quotes) console.log(msg.s, q.b, q.a);
};

Gate native format → Aeon format

What Gate actually sends for BTC/USDT, captured from its public WebSocket, and the normalised quote you receive from Aeon Feed. Depth arrays are trimmed for readability. Subscribed with interval "0" (no price-level merging).

Endpoint: wss://ws.gate.io/v3/
