I thought that the "new" VIX (based on SP500 options) will be under the old original symbol i.e VIX, and the "old" VIX based on the SP100 options will be under a new symbol VXO. Think I have got that right 🙂
The Volatility Index ($VIX) was changed on Monday by the CBOE to reflect the use of the SPX options now instead of the OEX options. In most cases the symbol on your quote vendors services will not change. But you should check with them to see if they use a new symbol.
