# Securities Request List (35=x)

Submits a request to get a list of the symbols available to trade on the exchange.

In the FIX (Financial Information eXchange) protocol, the Securities Request List message (MsgType = x) is used to request a list of instruments from the CLOB. This message is typically used in pre-trade workflows to obtain information about available instruments for trading.

The Zero Hash gateway will respond to the request by sending a Security Definition (35=y) message, which contains detailed information about the requested instruments, such as their names, prices, quantities, and other relevant attributes.
