There is a lot more than just commissions and data feeds to consider. The first thing I look at is the financials of the broker and their compliance/regulatory track record. Who cares if you save a few dollars but lose your account if the broker goes under - it happens. Pay attention to the column 'Excess Net Capital' - this is the brokers safety net - the smaller the more vulnerable you are. http://www.cftc.gov/idc/groups/public/@financialdataforfcms/documents/file/fcmdata0716.pdf
This is an inaccurate statement. These are AMP's default commissions for all AMP direct accounts. 3 pricing options with HVT as low as $0.15 per side + fees https://portal.ampclearing.com/account/commissionquote.aspx
I took a look at that as well and it's interesting. The excess capital rule makes firms like Ironbeam and AMP look suspect.
Tradovate. Here their RT fees (total cost) for some products I trade: Eurex (in Euro): FESX 1.1 FDAX 1.5 FDXM 0.92 FGBL 0.9 USA (in US$): ES 2.54 NQ 2.54 ZN 1.7 ZB 1.8 6E 3.4 CL 3.1 GC 3.1
In fairness, many on this board have tiny balances at their FCMs. They don't have much to lose in an FCM BK situation.
