Absolutely! It's incredibly simple. Be sure to login to both IB and CQG!
1) Pull up a chart using CQG, and for this example, ENQM20.
2) Right click on the chart to select Edit Instrument
3) Go to the Connections tab and select Add
View attachment 231
4) The Symbol Mapping box opens. Select the corresponding instrument from IB, so NQM0.
I'm not sure how you trade, using a DOM, the Trade Panel, or on a chart. For the DOM, make sure you have the CQG symbol pulled up, but select your IB account for execution. Same with the Trade Panel.
If you trade from the CQG chart, be sure that your IB account is selected when placing a New Order. Until you do this, the order will not reflect on the chart. In fact, if you have that chart open in different places, you have to make sure each chart has this setup to reflect your order.
I highly recommend testing this first by logging into your IB Paper Account (instead of your Live Account) so that you may see if it works.
Hope this helps!
