jmezz Posted January 21, 2016 Report Share Posted January 21, 2016 (edited) I notice when I try to display an option chart, it will not give any price action prior to the time in which I open the chart. I have accts at both Thinkorswim and MB Trading. I've tried setting each data source as default source but it doesn't matter which one I choose, I encounter this issue regardless. I've also tried right-clicking and choosing to backfill but that does nothing. Maybe I am not doing something correctly. I am including a screenshot of a chart that I opened and has built 3 bars. If I open an option chart then it will just show price building 1 bar and then go from there. Any help is greatly appreciated.

Jerry Medved Posted January 21, 2016 Report Share Posted January 21, 2016 You are not doing anything incorrectly. TD Ameritrade and MB Trading backfill does not work for options. You can click on the dropdown portion of the backfill button on the chart and select "Backfill Using.. " and select Google for the backfill source - that will backfill options I believe. Yahoo too, but only 1 day backfill Quote Link to comment Share on other sites More sharing options...
