There is a very good article in the education section of fxstreet that is worth reading . it is " How to set profit targets and control losses ". Within it it points out things like trading is " a series of compromises ", and demonstrates how open ended targets with an understanding of maximum adverse excursion is more profitable than targets. It highlights the importance of consistancy , and eludes to this fact by the very nature of the content.
It neglects to address the importance of the variable " opportunity", as it relates to expectancy, as well it doesn't articulate the importance of distribution effectively. Perhaps these items are to be covered in another article that builds on this one.
No doubt in my mind the core messages in this article are important building blocks to becoming a real technical trader as opposed to just another dart throwing monkey.
