Roll over confusion

[cognis0]

Hi,

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...

Hello cognis0,

You will need to switch instruments in the chart tool bar. So switch it from ES 06-15 to ES 09-15 for example.

The chart settings remain when you switch instruments this way.

Ah yes ~ thanks..
