Quote from let it run:
I don't think 7.5% +/yr is anything like a holygrail. That's a typical 'investment' and you'll get that if you invest in a balanced stock portfolio rather than 'trading', if you do it over the long term in almost any stock market.
For me, holy grail would be something like 500% p.a. with minimum stress i.e. drawdowns causing cashflow problems and casual monitoring of system as you believe there is no need to fade any decisions.
Don't want to be defeatist, but I think it's an order that is extremely tall. Realistically, it's your ability to manage your decisions and adapt to fundamental changes that makes you a star. There are a set of money management rules that you can create in a system with OCCASSIONAL justification for breaking them but I don't see how you can formalise a decision making model based on fundametals. Please let me know if you figure out a way of doing it though!!!
