Most people deal with optical illusions right on the chart.
Thus, I figure it'd be a good idea to apply them to putting patterns on charts to read them for a trade:
A rule from here (pg. 1) states that
"This apparent expansion of the acute angle occurs
at the angles between 0 and 90 in the Zllner illusion
(Morinaga, 1933; Wallace & Crampin, 1969). On
the other hand, in the tilt illusion, the acute-angle expansion
appears at the angles between 0 and 50, and, to the
contrary, the acute-angle contraction, called the indirect
effect, occurs at the angles between 50 and 90..."
One can put any shape up there, as long as its angles repeat from one of that shape to its next; the axis, of course, can change; and, there's no reason to miss a really-off-angling shape -- one can just consider it to be off the beaten path, and throw a multiple-lines pattern off it to see if it especially lines up to justify using it. For strictly doing an angle, a triangle helps imagine it, especially to trace, with a line between triangle centers, the price candles' path along the way.
The method needed some additions, such as whatever big-bunch-of-lines built-in patterns may fit in, and a genuine purpose for circles. Circle have infinite number of radiuses, so when they're showing a perfectly-balanced-within set of candles, that's beyond the <>50-degree angle rule (as I take it, from the source quoted in the last post). It's something to, this 'perfectly' being more or less the case, connect the dots a bit more between <>50d that suggest whether or not price'll expand and thus veer from, or contract and thus stick to, the direction one's big-bunch-of-lines built-in patterns and whatever line or lines one picks from them.
Hang onto the older big-bunch-of-lines built-in patterns and whatever line or lines one picks from them.
They are often pretty good, most of them (that is, the one Gann fan, in the example below), so it seems like a good habit to start -- even though I'll have to prune them once in a while. Finally:
Bring use of the angle method to be refined enough to be only a simple and straight-forward -enough use of the angle method to be an 'up-and-down now' idea.
