I use it with IB and have had great success. I'd been using the IB plugin for a long time and was using the order ticket until they added the account manager and trade manager windows recently. I just upgraded to 10.4 and started playing with the trading from the charts feature and think it's going to be a great visual indicator of where my open orders are. Looks like you can quickly grab and move positions if there's a fast move on the stock.
I'm not sure, but it also looks like you can change a limit order to a market order by just grabbing it in the chart and moving it to the price. I want to play with that more in the paper trading before doing it with IB, but I like the way everything looks.
Cheers,
Paul
