There are so many different sources of information concerning trading forex however, not all of them deserve our trust.
I believe that everyone should start with some educational materials which are free of charge. For example, you can start with forex military school which can be found in the Books section in this website. There are many different articles which are devoted to trading and they are organized in the right order so that you'll be able to learn forex step-by-step starting with some common information and gradually move to the specifics. Apart from this forum, you can also find lots of useful information on babypips where there is also a nice educational center full of educational articles on forex. More than that, I know that many brokers also tend to make their own educational center. I believe that you can ask your broker if they have such.
Later on you can simply ask the questions on different forums about the details of trading or in search of new trading strategies which will make your trading more diversed and profitable.
