It's not a "fact". It isn't true. It's wrong.
Find the posts of Rhodytrader, Clint, Laughingcharlie, Lexys and others, if you don't want to trust me for it. They've all explained it countless times, here.
Then you haven't looked very far. Even Google would help you with that one. Or this forum. Or any other trading forum.
As I've been explaining in a couple of other threads, over the last few days, THIS is the kind of thing that really puts me off posting here.
The fourm's full of deeply erroneous statements, often stated with some force and emphasis, as if they're factual, when actually they're just WRONG.
The beginners using this forum (at whom it's aimed and for whom it exists) don't know any better, and can easily believe all this stuff, if it isn't corrected.
They can look at the totally mistaken statements made so emphatically as "FACTS" like the ones just above, and at accurate and helpful observations and advice posted by people like Charlie, with his experience of decades in various aspects of the industry, and they don't know the difference between the two, so they can't tell whom to believe.
And why should they?
It's a problem, and it's a shame.
Other trading forums seem not to have this problem.
Maybe mostly because they're far better attended and busier, and there are much larger number of more experienced members ready to shout down all the misinformation when it occasionally appears? I don't know.
Sorry to complain, again, but it's a real problem here.
