I am currently using MC with IB datafeed to trade futures. I would like to have the US stocks, ie, IBM feed into MC. Can someone please tell me the root symbol that I am supposed to use on the "symbol root" on the quote manager ? I've tried "IBM", but it doesn't work. is it "IBM US" or something ? similar questions, for HK stocks, 949 HK. what root symbol should I use ? many thanks...
