I tried demo'd FXCM, Forex.com, ACM, and GFT. I finally opened the account with ACM. I have been there since november 07 and I have not had any problems. They have all I need as far as chartinng goes. They allow me to set up audible alarms and I have not had any issues with stops or things like that.
I know how you feel because the hardest thing for me was to open an account and trust any broker with all the stuff you read on the net. Some people recomend one and almost immediately you read something else that the same broker stole all of some ones funds. The fact is most of those people would have lost all their money anywhere because they probably went in with $1000 and leveraged themselves 100:1 on one trade that went against them. From what I can tell, demo all the ones you can, of the big names, see which one you like and suits your trading needs. And go with that one.
There are successfull traders in FXCM, GFT, and ACM (ME!! hahaha...
and many others. Go with what you feel is good for you, start out small, get your feet wet and change if you have to or increase as you get comfortable.
Well that's my two cents...maybe worth less than that..but good luck trading.
