Recently I happened to derail a thread whilst discussing the topic of positive expectancy.
Given that one of my pet hates is the tendency of experts to overcomplicate the simplest of concepts by impressing the importance of superfluous mathematical operations, thereby causing needless confusion to market newcomers, I decided that this topic warrants a thread of its very own.
Those acquainted with my various posts will probably already be aware that I tend to take a macroscopic/quantitive approach to measurement of overall system performance, and prefer to avoid excessive degrees of analytical dissection.
As such aggregate calculations often amply serve my needs.
I do understand that ,depending upon one's methodology, some additional component measures may indeed be useful.
My concern with trading, like so many of life's endeavours, is that it starts to become a religion where people become so attached to specific rituals and doctrine that they not only lose sight of the original purpose and intent, they also at times become zealous to the point of fanaticism.
I'd be interested to hear others' thoughts on this topic and, should this thread progress,, intend to share a few anecdotes of my encounters with newcomers whom I believe were effectively sabotaged by the religious zealotry of various market gurus.
