It's interesting that the broker offers such a wide array of accounts with different specifications but doesn't impose any strict requirements for minimum deposit. So you feel free to enjoy the range from $50 to $500 depending on the account your choose. It seems to be quite convenient. I went for live zero fixed spread, as I am truly convinced commissions are more favorable to pay. Ironfx makes an emphasis on the variability of order execution, but I personally feel no difference. Whether this is STP mechanism or another one, no matter at all. Orders are executed quickly all the time.
