I have found on FutureMag some articles about building a trading business plan.
That will be your first step before building a trading system.
Theses articles begin with an introduction to the trader’s business plan then talk about markets mixing, learning, staying informed… Others aspects like finding a broker, software and hardware needs in future trading, and regulations are also covered.
I have read theses articles and found them very interesting, maybe they are more oriented to beginner traders but can be helpful to everyone.
A business plan is different from a trading system plan, this plan will help trader to stick to rules that are important for their long-term trading career, you will be able to identify your resources’ need, your potential problems and find suitable solutions that will help you became a profitable trader over the long-term.
