may be too much to ask for. but I want to have a quick glance at the way an option price varies. during the day/week range I have seen in OptionsXpress, you can see a yearly chart for option leaps. see the screenshot of SPY 60 MARCH Put. IT IS THE BLUE line. but scottrade/ tradeking, Optionshouse, dont show me a weekly or daily chart may be most are so volatile that , its not feasible. ? Infact sometimes. with low volume, the bid ask of the particular option will have fluctuated much more than the day /HIGH /LOW range and that usually is not captured. when we look back all we find is the OPEN /CLOSE prices.
Try: http://www.crimsonmind.com To get recent daily changes for a specific strike I use this method: Enter any quote (say: msft) then click column Strike (History) in the quote table. I use intraday snapshot from the site as well. You can get historical quotes as well (manually, day by day what can be tiresome if you want a range of days). I have learned a lot looking at daily changes for a strike (you could really observe all the greeks in action).
Do you know if ToS (or any other tool) lets me plot the difference between underlying + option price? Ie, if I wanted to see how covered call premium was moving?
