Beginning February 12, 2010 a number of significant changes come into force for participants trading, reporting and managing options. RealTick fully supports these industry changes, which will make execution in options easier for traders and investors.
These changes relating to option symbology, how the instrument is commonly designated, include:
-
A migration from OPRA’s (Options Price Reporting Authority) code to a clear definition based on multiple fields – the option symbol, maturity, day, call/put indicator and strike price
-
All equity strikes, currently in fractions, will be decimalized
RealTick has, since mid 2009, been working closely and testing actively with the industry and key partners to ensure full operability, support and a seamless transition to the new symbology for clients.
