I explored [B]FX Choice[/B] briefly; they do accept U.S. clients at the moment.
Platforms: MT4, ECN, lots of mobile apps, Web.
Minimum deposit: $10
Spreads: These are minimums: E/U .5-1.5, G/J 2.0-5.0.
Max Leverage: 1:200 for MT4, 1:100 for ECN
Max lots per ticket is as low as 1 for the ‘start’ type of account. For all, .01 min size, .01 step.
[B]FXCC[/B] was mentioned. They do not accept U.S. clients, but Legal informed me that U.S. directors/officers of an offshore-from-U.S. corporation are perfectly acceptable, as is a U.S.-resident trader with such an entity. They are Cypriot and brand-new in 2010; one of their officers previously worked for Inland Revenue so you can imagine whether they cross t’s & dot i’s.
Platforms: MT4, MT4 Multi-account, Currenex, Mobile, Web. Also managed accounts.
Minimum deposit: $1,000.00
Spreads: vary by platform, account type, and time of day. For low-figure MT4 accounts a good estimate is 1.3 on EU, 4.3 on GJ.
Max Leverage: 1:500 available up to $50,000.00 balance; the exceptional Support crew inform me leverage is negotiable somewhat thereafter, case-by-case. Max lots per ticket is 40, but also negotiable. Minimum is .01, step is .01.
[B] IRON FX[/B] is on the same roster: no “U.S. clients,” but U.S.-resident traders and directors/officers of an offshore entity pass muster no problem.
In fact, if you like “hmmm” moments, they have nearly the identical terms and conditions of FXCC.
They’re in Cyprus with offices in a building I personally know exists, and they’re regulated out the yin-yang by the various Cypriot and European agencies, etc.
Platforms: MT4, MT4 Multi-account, Mobile, Web. Many account types, including "STP/ECN."
Minimum deposit: $2500.00
Spreads: EU 1.2, GJ 4.5.
Max Leverage: 1:500 (with no balance-based scale according to the able Support ops), and again 40 lots max per ticket. Minimum is .01, step is .01.
