if need transform data on stream, perhaps use node.js module called scramjet. allow modify data on fly, before pushing them page via socket.io. example if compress data little

const io = require('socket.io').listen(8080); yourforexstream.pipe(new scramjet.datastream)     .filter((forexitem) => typeof forexitem.tick !== "undefined")         // don't send heartbeats, ticks     .map((forexitem) => forexitem.tick)         // send tick data     .on("data", (tick) => io.emit("tick", tick));         // broadcast socket.io
