Drawing a Circle on the chart

[sgbaum88]

I was wondering if there is a script for placing a circle between two points on the chart instead of using the ellipse tool? I find it very difficult to accurately do this with the drawing tool that TOS provides.

just wanted to let you know, i have been experimenting with a study to draw a circle.
as this is a fun math experiment, and not really useful for trading, it's low on my priority list.
it may be a week or 2 or ? before i finish it.

the user enters 2 dates and times and it uses the close from the 2 times and draws a circle through them.
with x an y having different units, there needs to be some sort of correction/scaling, to keep the 'circles' close to being round.

Thanks for your efforts! Keep up the good work!

Thanks, Halcyonguy. I would like to a parabola drawing tool for head and shoulder patterns, cup with handles, saucers, etc. It sounds like you're the person to get it done.

start with looking up some formulas.
https://www.cuemath.com/geometry/parabola/
https://www.radfordmathematics.com/...rm/vertex-form-finding-equation-parabola.html
experiment with them, and try to draw them starting from barnumber 1, barnumber as X , and calculate a price.

something to get you started

# parabola_ex01
# https://www.cuemath.com/geometry/parabola/
# y = a * (x - h)^2 + k
# https://www.radfordmathematics.com/functions/quadratic-functions-parabola/vertex-form/vertex-form-finding-equation-parabola.html

def bn = BarNumber();
def na = Double.NaN;

input parabola_vertex_barnum = 100;
input parabola_vertex_price = 50;

input a = 0.2;

def h = parabola_vertex_barnum;
def k = parabola_vertex_price;
def x =  bn - parabola_vertex_barnum;

def y = a * power(x - h, 2) + k;

plot z = y;

for cup and handle, look at this thread.

he is a genius with thinkscript . his forum is another place i learned quite a bit about thinkscript. look for posts by robert.
