I speak from experience: whilst the account balance < $10k I pay the same as I did with IB ($4.04 RT per ES contract and that's via the CQG route).
Our equity deposit is now > $10k so I understand from
http://www.ampfutures.com/Cost_Calc.html that we should start getting $3.54 per RT starting next week.
We're 2 weeks in with AMP and so far the staff have been efficient and professional (I had to use the Live Chat to check the status of an account deposit and email to make an account enquiry).
The biggest positives over IB for me are:
- I get a decent platform to trade with (MultiCharts.NET)
- Good quality tick data (IBs datafeed didn't support my trading signals which require real tick data as opposed to the time-sampled data that IB provide)
- The margin leverage ($400 per contract during the day is astonishing) - though you have to know how and when to use it or else a poorly managed trade can very quickly wipe your account clean!
And a couple of minor drawbacks:
- We're an international client and with IB we can do account withdrawals for free, AMP charge $30.
- There's a $25 per contract fee if AMP are forced to close your position for margin / liquidity issues. Again, only a problem if you have a poorly managed trade.
All in all I'm happy and am unlikely to switch away from AMP as long as service availability and reliability remain good.
