WebSocket Market Streams
Book ticker stream
Stream Description
Best bid and ask, Binance-shaped. This is the same underlying quote as @tick — MT5 publishes
one bid and one ask with no size attached, so B and A are always "0". The stream exists so a
Binance-shaped client can subscribe to the name it expects.
If you want the real book, use @depth. If you want direction and tick
volume, use @tick — it is strictly more informative than this stream.
