QuoteDislikedBeing objective in the method you use to measure and define a 'trend' or 'range' does little to avoid the fact that accepting such a definition is completely subjective.
I first thought a range was special because it was mean-reverting (opinion). I found no evidence of mean reversion in a range (evidence based rejection of the belief). Of course the price stays around an average price since there is no trend but nothing I could identifier MAKES it stay there. Nothing forces it back to the mean if it wanders too far away from it. Not only I found no "rubber band effect" but I found that if the price goes too far it tends to escape easily (call it a breakout). Without evidence of this reversion I can only consider a range to be no more than a trend with a slope of zero (just a special case). Should a strong evidence that there is rubber band effect, at least some times, I would have to reconsider. This is the Bayseian idea: prior belief -> observation of evidence -> posterior belief.
QuoteDislikedYou are being objective in saying that within a chosen price series your chosen model objectively defines a 'trend' and/or 'range'. Of course, when you define your scope of study you can objectively describe what has happened in the past. The market (the totality of buyers and sellers) may not share your definition and the limits you set.
QuoteDislikedAllusions to 'trends' in the present/future such as in a statement like "the market is trending" or your own "shall I stay with the down trend..." are necessarily a projection of an expectation of the future; a notion that does not rise above the level of an opinion.
QuoteDislikedthe very idea of trading with the 'trend' (or against it, if you fancy losing) contains a belief about the nature of markets and an inherent expectation of the future
QuoteDislikedObjectively defining what constitutes a 'trend' (even if you use a complex definition involving different fractal resolutions) cannot avoid the fact that speculation based on this concept is very much rooted in one's personal opinions.
And no, following the trend is not only an opinion or a choice. It is again based on stats. What is a choice is the scale of you trend.
No greed. No fear. Just maths.
