My attempt to resolve some of the issues:
1. Scam brokers
Same like all things, there are scams. Even buy any products eg beauty products also got scam. Agreed with luqmanz - NFA regulated brokers - which simply means, those who abide by rules and regulations by a governing body - same thing with food products imported by US are regulated by FDA, or like our own SIRIM mark etc.
Myself, using IBFX but with US, as that time, they did not have IBFX Australia and I m still too lazy to make the clicking to switch to IBFX OZ.
2. Risk reward ratio 1-2
Depending on your strategy. In my earlier years of trading, I ve used before risk reward ratio of 1-1. I ve also used R/R 1-5, etc etc.
At the end of the day, RR 1-2 is a general guide. It really depends on what you re most comfortable with.
3. Starting up.
FOr those who interested to start, few things to learn:
a. The mechanics of the platform - download demo version from brokers like IBFX or Oanda or any other which you like.
b. Know the difference between fundamental approach and technical approach. Resources like investopedia may come in handy.
c. Within the fundamental or technical, there are many methods and techniques available. Some prefer this method, some prefer that method.
d. Know that there is no shortcut. No one can provide the quick fix DIY. Forex is probably the most liquid and its movements the most volatile. Many big hedge funds and government are into it as well. We re playing the field with players with such buying, selling, holding power. Suffice to say, on paper, it will look like we do not stand a chance.
The shortest cut, so to speak would be:
i. Join and attend seminar - those 2-3 days seminar for your first background introductory. Cost: Probably in the region RM5K - RM10K. I have no idea, as I have not attended one myself and am not too sure of current market rate. Do not expect to make $$$ immediately after attending seminar. Not possible.
ii. Read and explore the ideas and methods and see which is suitable for you.
iii. Test it out in DEMO version. See if it will even work in theory.
iv. Test with real money. Yes, test. LOLz. 99% of ppl will lose the money, hence test

v. Keep trading and improve on your skills.
vi. Dont forget to have fun

Good Luck and Happy Trading!
