hi guys, i’m new here… first of all, i wanna thanks to google that bring me here :51: LOL
my questions are what is the different between forex with other investment stuff like stock,option, and others ? for completely newbie in investment field and have no finance background which should i choose forex/stock/option or others ?
n any bad/good stories to tell about Gain Capital Broker ? thanks in advance guys 
I think the keyword there is ‘investment’, stocks and stock options etc. are investments, forex is a skill to learn.
That depends on your goal. If you want to lose money quickest, I would start with forex, overleverage and overtrading, lol. Because there you have highest risk. Then next would be options and at least stocks among that goal.
Frankly, can you comfort yourself with the idea that it will need a little work for a couple of years to learn almost everything about markets, fundamentals and technics and all that to become profitable one day in the maybe not so close future? Then if you still want to learn something regarding fx there is the bp school where you could start. Best of all, you can use this knowledge partly also to trade in stocks or options.
Regarding your decision: That can nobody decide beside of yourself. You can invest/trade/whatever in all three segments or in just two or in one. That all depends on your individual risk appetite and tolerance, what capital is on the table, your skills, etc. etc.
I hope that helps. 
Buckscoder - you say learn about ‘fundamentals’ - you must learn to stop swearing!
Swearing? Where do I swear? I am as gentle as I could, lol.
