# Prices

If you send a **`PRICE_SUBSCRIPTION`** request with an **empty `priceSubscription.markets` array** (or omit the field entirely), the server treats it as a *wild-card* subscription.\
Instead of returning prices only for specific *currency / cryptoSymbol* pairs, the web-socket will stream **every market the platform currently supports**.\
Use this convenience feature when you need a complete market-data feed without enumerating each currency pair yourself.

## Get Prices

> Get prices from websocket.\
