disclaimer: NFA, i'm noob, i make this stuff up as i go. you should play too but always be humble and use stop loss and remember "this market.........is volatile" to quote bitboy
1. scale chart properly (this is 100:1; that means every $100 = 1 time unit which is 15 min here). this is important, and lock the scale when you find one you like bc if you adjust it, your circle will shift (try it). this can actually be useful FOR scaling/squaring properly (example: i will draw a fib 'circle' (actually an ellipse) between points and adjust scale until the ellipse becomes a circle)
2. make a circle (fib arc) of time difference between top and bottom, horizontally (not angled) that means the radius of the circle = the time of the move. that's the unit circle. that's 1
3. copy and paste that circle and make each one's radius a multiple of the OG unit circle (settings and put your levels in, just like normal fibs). i do square roots but you can do phi and its multiples as well. i go up to 6.854 and 11.089 sometimes, depends on chart (TV defaults to doing phi multiples all in the SAME circle (aka concentric circles aka archimedean spiral) but that's not how i do it)
4. fit circles to tops and bottoms. play with different arcs of the circle, the top is its own convex arc and the bottom is its own concave arc for example
5. i'm obsessed with the idea of 3 taps (on flags and trendlines and beyond), which i think comes from the idea that every 3 non-linear points make a circle. so if you touch a circle twice, the third confirms = bounce? idk. also applies to planes which is what's really going on here, 2d is scamfu. idk i try to ask myself "if i were a price action inside the chart rn what would i do?" and on the third tap i would be like 'oh ok cool this is confirmed now, that was fun, my work is done and i'm bored, now i can bounce')
6. sometimes it's horizontal tangent lines to arcs (aka the line that touches the circle at the bottom or topmost point)...bc this represents the radius at its extreme, at the limit of price change. support.
circles are the bridge between worlds, they are the way to translate and project from one axis (time) to another (price). you're just using the radius as a ruler essentially
michael s jenkins (find him on youtube) is essential...his idea, probably inspired by gann, is that time=price. it's the basis of the idea that you can do geometry on charts. time cycles. planetary cycles = time cycles. i recommend watching his videos on .75x speed and pausing frequently at first
getting into bradley f cowan, absolutely brilliant
