This is the problem. Market makers are very successful because they know that the attitude to FX and other markets is one of childishness and boyish enthusiasm. Unfortunately I can’t be sympathetic to the post because you won’t tell someone you are a surgeon because you have scalpel. I think it is good this happens, it makes people respect the business and realise that it requires the mentality that say’s how best can I screw the broker rather than how hard can I work because that is part of the game. The broker still stands between you and success.
This is how grown-ups and professionals think that is why there will always be rate manipulations, bankers being murdered by the mob , flash crashes, etc. It is how to play and win.
