IMPORTANT: Market data streams will terminate after 15 minutes. Users must send a new request for market data after 10 minutes to continue retrieving data for the instrument.
NOTE: The maximum number of market data subscriptions is based on your account’s Market Data Lines.

Topic Target:

Contracts requested use SMART routing by default. To specify the exchange, the contract identifier should be modified to: conId@EXCHANGE, where EXCHANGE is the requested data source.
Combos or Spreads market data can be retrieved using identical formatting to Combo or Spread Orders. The only difference is that a spread_conid of 0 must be passed.

Arguments:
