Market Data

Real-time data is available to all Tradier Brokerage account holders for US-based stocks and options. If you are not a Tradier Brokerage account holder, we are unable to provide you with any real-time data solution.

Symbology

We use standard symbols for most equities and ETFs. Options require the standard OCC symbology to be used. Investopedia has a good explanation of the symbol and its parts.

Warrants and preferred class (and other specialized) securities will use a / in replacement of a . which is sometimes used at other brokers. For example:

BRK.A should be BRK/A BRK.B should be BRK/B

Note: There is a difference between the option root and the option underlying. For BRK/A options, the option root is still BRK.A while the underlying security is BRK/A.

Real-time data is pulled from a consolidated feed from all exchanges. Delayed data is constructed from the same feed but is delayed industry-standard 15 minutes.
