I have the same problem. I use IB to trade the products on exchanges I don't subscribe to( With most FCM you need to have real time datas to trade a product ). I recently subscribed to ICE Canada because I was losing too much on Canola trading blindly, even if I barely trade it 10-20 times a year. You should try to check the last native print ( delayed )on websites like barchart. With the last level traded, you get a better idea of where the native spread is...
