If you go to the technical Analysis section on that thread
you will find numerous papers on various different TA methods
such as moving averages, Bollinger bands, Relative strengths
etc etc.
You will generally find a mathematical result concluding these papers...Most commonly the results are marginally positive and can be as poor as 50/50 when trading costs are added.
So one needs to progressively add complementary oscillators to a chart template..
charts are also the best way I know of setting a trailing stoploss.

So simply put with a coin toss selection or a bit better using TA
You can stop out your losers and only need
to let profits run and catch them.using a trailing stoploss..at a higher % to improve profits. Naturally winners increase and profits, when watching the trade run in technical boundaries...simple trends as you say yourself..


If you find a different mathematical conclusion on some of those results
let us know..ie.they do include bull and bear market % factors.....
And no one is using charts on high specs, like oilers thats just silly or the trades are smoothed out over a long term
