Tokaiwa investments fucking suck. If I am not mistaken they offer you the fantastic deal that you bring $50,000 and they "guide" you on how to trade -- letting you keep 50% of the profit! At no risk to them!
Anyway I did a lot of research and a bit of learning the hard way for anyone who is interested. As a US citizen and Mac user I opened an account with thinkorswim.com. Let me be clear that I put in months of reading books, websites, watching DVDs, listening to podcasts, demo trading, etc, until I felt basically frustrated that the money I was making was theoretical. Especially with the steady declines in the dollar at that time I wanted to cherry pick the best trades I could and do it with real money.
My first week I did ok. 3 small, low risk trades, 2 of which were successful, leaving me about $170 up.
Unfortunately during just that week I came to realize thinkorswim SUCK. For reasons I am not even going to go into here; suffice to say if you are unable to process orders, or predict what may or may not happen to previously placed orders regularly for hours at a time, you are not a broker I am comfortable trading with.
I actually fixed up my old Windows machine just to be able to have other options, fired up Metatrader, which is clearly the trading platform of choice (compatible with a variety of brokers) and opened an account with Alpari UK, highly recommended personally and good reputation via online research.
They do not allow US citizens living in the US to open accounts (for reasons I do not know) but fortunately not living in the US, I can use them.
Very happy so far and looking to continue placing small, conservative trades, hoping to grow my account.
