On the main C2 screen there is a drop down for C2 Resources and then an option for Symbols and Margin. Alas, when you click it you are taken to a page that only shows futures symbols.
Via a Google search I was able to find another page explaining the symbols for stock and ETF options. Unfortunately, there doesn’t appear to be any information for stock index options. Even if it were the case that C2 only offers one contract - SPX index options - it would be extremely helpful to express that fact transparently to users.
In the meantime, has anyone figured out the full list of available stock index options? Please let me know.
Thanks for your help.
