Well g,
Don't get carried away now, there are definitely exchange fees and commissions !!!!
Something has to pay for maintaining the account, support the trading, the Real time data stream (derived from your selected "watch list") and same for the real time streaming charts. The charts are fine but are not "Qcharts" .
The BIG PROBLEM IS THE COST !!!!!! A round trip Futures trade is about $10 give or take a little - as it does vary by product. There is a "minimum number of trades per month" but I seriously doubt you would not meet it. Do your own DD on options/stocks etc. They are likely as "horribly expensive" as an RT futures trade !!!!!!
I have been offering this info for at least 5 years when someone asks, but many do not read.
So, do your research. When you figure out how much money you saved, I'll be happy to tell you where to mail the check !!!!!!
