# Symbol order book ticker (MARKET_DATA)

## API Description

Best bid/ask. **For MT5 this is the same data as `GET /v1/ticker/price`** — the trade server's tick
carries one bid and one ask with no size attached. The endpoint exists so a Binance-shaped client
can call the name it expects; `bidQty` and `askQty` are always `"0"`.

If you need real depth, use the `<SYMBOL>@depth` WebSocket stream, which is available on request
(see [Symbol depth stream](/websocket-market-streams/symbol-depth-stream.md)).
