As per: http://www.ninjatrader.com/support/h...es_contrac.htm I have removed/added the new contract in instrument manager, and added the new contract to the chart, but when I attempt to remove the old contract from the chart I get "The primary series..cannot be deleted"
Also how to I ensure the previous contracts parameters in the chart data series are copied across to the new contact ~ Tick value, bar settings, days to load, etc, etc?
Thanks...
