Exchange Input Component

The Exchange class is a special type of string object. It behaves and evaluates like a string, but is extended with input validators and output formatters.

Use this class for functions with an 'exchange' parameter, or to convert between MICs, exchange acronyms or names.

Import​

from openbb_core.provider.utils.exchange_utils import Exchange

Usage​

Initialize the class with any of the accepted inputs:

  • ISO 10383 MIC codes (e.g., "XNAS", "XNYS")
  • Exchange acronyms (e.g., "NASDAQ", "NYSE")
  • Full exchange names (e.g., "New York Stock Exchange")
  • lower_snake_case names (e.g., "new_york_stock_exchange")
>>> e = Exchange("nasdaq")
>>> str(e)
'XNAS'
>>> e.mic
'XNAS'
>>> e.acronym
'NASDAQ'
>>> e.name
'NASDAQ - ALL MARKETS'

Properties​

  • mic : str - ISO 10383 Market Identifier Code.
  • acronym : str - Exchange acronym/short name.
  • name : str - Full exchange name.
