john cee Posted March 5, 2020 Report Share Posted March 5, 2020 Not sure if this is a bug with Historical charting ....Is it possible to update the chart so it continues where the ticker change has left off? This happened recently with BIOS... changed to OPCH and now historical charts only show from when the ticker changed.. TD ameritrade charting shows the full historical chart prices normally after the change, just not in medved trader historical charts. thanks for reading JC Quote Link to comment Share on other sites More sharing options...
Jerry Medved Posted March 5, 2020 Report Share Posted March 5, 2020 TOS uses a different datafeed. MT has no way of knowing about the old symbol name. If you enter OPCH as the symbol, MT requests backfill for OPCH. It is up the datafeed to merge the data together. you can however open a chart for OPCH. Do "Backfill As..." and enter BIOS. Then, do Backfill as AGAIN and do as OPCH. Make sure to do the 2nd backfill as or it will continue to try backfilling with BIOS. Quote Link to comment Share on other sites More sharing options...
