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.
