No. The first mistake a Forex trader can make is to have a dead-set opinion and then search online for opinions supporting his pre-conceived notions. If anyone looks long enough and hard enough, they're going to find someone somewhere to agree with him. Taking that into account, the question still remains: Who do you listen to?
Do some research. There are Forex trading groups all around the Internet. With a little research, you can find out which are the most successful and some even have mentoring programs. Don't stay married to any particular group.
