So far I have only found two sites that offer completely free option charts for stocks, Exchange Traded Products, and indexes: BigCharts and QuoteMedia. I provide more information about them below. OptionZoom provides free option charts, but apparently only for large cap stocks.
Recently Schwab (StreetSmart Pro) and Fidelity (Active Trader Pro and standard web site) have started offering option charts to customers, but they require you to at least setup an account with them.
BigCharts uses their own custom option symbols, not the Fidelity or Schwab flavors or the “standard” option symbol. To get the BigCharts option symbol to use, enter in the underlying symbol (e.g, INTC) towards the top of the screen and click one of the chart buttons. Then click on the option chain link above the quote information to show the available options. Click on the “quote” link in the option chain to get a chart. Once you get a chart you’ll probably want to click on the Advanced on Interactive Chart button towards the top to get more control over the chart.
BigCharts avoids the huge issue of charts not being available after the options expire. But it looks like it still suffers from the problem that intra-day information becomes unavailable soon after the options expire. They need to allow a range of dates to be displayed, not just assume that you want everything referenced back in time from today’s date.
To generate options chart from QuoteMedia, start at their http://www.quotemedia.com/ URL and put a stock symbol in the quote field in the upper left and then click the “Go” button next to it. Then you should see a detailed quote for the symbol. Click the “Options” link towards the top and you should get an option chain. Decide the strike price you are interested in and then click the underlined date field for the call or put you are interested in. You should then see the option chart with time span selections at the bottom of the chart.
What I would really like options charting packages to do would be to chart bid/ask values if actual trade values are not available. Since many options are lightly traded their charts are deserts of information. Bid / ask history would be much better than nothing.
