Knowledgebase: Why are my charts/option chain not updating even though I'm linked to TOS? Why does my risk chart look wrong when linked to TOS?

The industry wide OSI code change (from OPRA codes) is continuing with the move from Conversion to Consolidation phase until May 2010. Each class has its own timetable for this change (see OCC link).

As TOS move to consolidate each class you will need to change the setting in OptionNET Explorer (Configuration tab->OSI Phase->Consolidation) BEFORE linking to TOS (changing the Trading Date to today). This will enable ONE to continue to request prices for the option chain and update the prices, option chain, charts and greeks respectively.
