I would open the chart to show the continuous contract in chart.
For example: I would like to open an chart of ES (from 2009-DEC-01 to 2010-MAR-05)
This involves getting the data for ES 12-09 and ES 03-10
I expect that when I open the chart, it would show the data of ES 12-09 from 2009-DEC-01, and then beyond the rollover date of ES 12-09, it would show the data of ES 03-10
May I know how to achieve this ?
thanks !
