Hi guys- I'm considering doing some ES trading. Right now I trade the SP500 via spy,sds,sso, etc. but my platform and fees leave some things to be desired to be the most efficient I can. So, I'm looking to try trading the ES and see how that works out- the commissions are certainly better, and it seems to be setup more towards my trading style. However, my current broker is TDAmeritrade, and I don't believe I can get the ES live data from them to pull into my charting software (quotetracker) I like quotetracker, and would love to keep using it, but I'm going to need a futures data source. I'm wondering if you can give me any leads as to good sources for futures data (QT is compatible with many data sources) Something fast and dependable is desired.. and as inexpensive as possible (free is good too) I know Think Or Swim has the data, but I'm hoping to not have to switch over to new charting software if I can avoid it. Thanks for any tips!
