Good TA chart will be the most simple, obvious and systematic one...we'd better not draw the lines to fit the chart, or force to let the chart happen... just let the chart speak itself, The common pattern that most likely to happen should be the one recognized by most of the crowded on the first sight... but of course some poweful ppl will use this common weakness to create so called "false signal".. Again no 100% thing,, it is probability....
