Add Equity Index Symbol transition documentation #139

mm0 commented 4 months ago

In the transitioning from TDA documentation, there is a section for the new format of Option symbols. It appears as though the format for equity index symbols has changed as well.

Previously, you could do a level_one_equity_subs for SPX and VIX indices using symbols:

These no longer work, however the more common formats do work:

These can be confirmed by using the developer.schwab.com CUSIP search (searching by symbol for these doesn't work and didn't with TDA either) and have been confirmed by using the early mentioned level_one_equity_subs in schwab-py:

Describe the solution you'd like A short mention of this new symbol format to be added to the documentation.

Describe alternatives you've considered Google search results will index this Issue in order to help others wondering about the same issue.
