So what, exactly, Hadden, is the "minimum"!!!?? Is it "8"or "10" or "15" years (or maybe even more?)
And where do you guys get these figures from? What statistics exist for this kind of claim apart from forum gossip, random speculation, heresay and "thin air"?
Are you really saying that someone could be losing for up to 15 years before making a consistent return on their trading?
Surely, if someone has not "got there" before eight years then they are either broke or in serious need of finding something else to spend their time on............?
Trading ability is not conditional on the passage of time, but on the effort and dedication applied to it. Of course, it takes its own time, but the duration is not the key element. It is the effort and the pre-requisites of sufficient capital, a suitable broker, intelligence, psychological profile, research, performance analysis, education, development, etc.
If you just keep repeating the same (losing) approach in your trading without learning or developing then it is immaterial whether you continue for 3, 5,8,10,15 years, or even forever, nothing is going to change.
