If you have TOS client, you can use check under market depth to locate put and call volume and open interest. For Oct 9, call vol = 710 and put vol = 745. I used to use OEX pcr blindly. However, over the years, I have become a bit more sophisticated in interpreting the data. Specifically, knowing whether volume is opening or closing makes a big difference. As you must have observed over the years, often very high OEX PCR doesn't necessarily trigger any sell the next day. That is because often the large put volume was due to short put being initiated. In my view, such trade isn't necessarily bearish (if not a bullish bet). On the other hand, when such short put transactions are being closed, this tends to have bearish implications. What's more, put sellers may be wrong. Many times I see new short put transactions being put on, and only to see them being closed out later on the day for a big loss. Such round trips also tend to elevate put volume substantially (and in turn PCR) as well.
