1. the data is from Google Finance. So it is at least 15 min delay.
It does not matter much to me as I can only check out my options strategy at night.
That said, if you could suggest a real time data feed, free, I could write a data interface to adopt that.
2. Could you give more details...
please try out the excel spreadsheet that I made and see if that fits you.
any suggestion is welcome!
