2) Deprecated v1 account/trade/order endpoints removed.

3) Beta feature: New real-time "bookTicker" streams

{
  "u":400900217,     // order book updateId
  "s":"BNBUSDT",     // symbol
  "b":"25.35190000", // best bid price
  "B":"31.21000000", // best bid qty
  "a":"25.36520000", // best ask price
  "A":"40.66000000"  // best ask qty

You can access these streams by connecting to:

or
!bookTicker

This wil push a bookTicker payload every time the best bid or ask's price or qty changes, in real time, only BNBUSDT.

This will push a bookTicker payload every time the best bid or ask's price or qty changes, in real time, for all symbols.
