Still does not work, this is very frustrating.
I DO OPEN the option chart from the IBM Option chain window, is that why it does not work either using Yahoo data? I am unsure how to change a symbol in a Hist. Chart window that is already open, as I have always opened charts by right clicking the symbol from a watch list.
I have added the IBM option symbol ((( .IBM_171215C155 ))) into my watch list, right clicked both the Hist & Intraday charts with Yahoo as data source in the chart window and still NO BACKFILL--> do I have to change the data source for my watch list also to make this work? If so, I'll PASS on trying to figure this out.
Sorry for effort but if we can't fix this I'll revert back to the TOS charting system for this matter.
PS.. I am doing now this AFTER the Market has closed could that be a problem as to the timing and maybe it works tomorrow....just saying.........
