Quote from AMP_Trading:
The daytrade margins are $100, so even with $500 account you will have access to tradeable markets.

On your list I see DAX initial margin ⬠13950.
This is ridiculous!
From Thursday, 02/10/2011 to today (Monday, 02/21/2011) DAX moved at max 160 points (from 7280 to 7440) which equals 160x25=4000 â¬.
There was even a major trending day in this range (Friday, 02/11/2011).
As we all know volatility has decreased recently noticeably.
So the (initial) margin is in absolutely no relation to realistic, expectable moves.
