OneChronos trading instrument symbology
OneChronos supports three symbology conventions:
- CMS Concatenated. Subscriber must populate the
Symbolfield with both the root symbol and a CMS suffix, for symbols requiring one. A single ASCII space must separate the root and the suffix. Example:Symbol=BRK A. - CMS Suffix. Subscriber must populate the
Symbolfield with only the root suffix, andSymbolSfxwith a CMS suffix for symbols requiring one. Example:Symbol=BRK,SymbolSfx=A. - NASDAQ Integrated. Subscriber must populate the
Symbolfield with the root symbol and append a NASDAQ Integrated suffix for symbols requiring one. Example:Symbol=BRK.A.
Symbology election occurs on the port level. The table below is a comprehensive list of security categorizations (not all of which are necessarily tradable on OneChronos). Note that we include a column showing the mapping from CQS symbology to CMS/NASDAQ Integrated, but we do not support CQS.
