█ OVERVIEW
Library "e2hray"
A drawing library that contains the hray() function, which draws a horizontal ray/s with an initial point determined by a specified condition. It plots a ray until it reached the price. The function let you control the visibility of historical levels and setup the alerts.

hray(condition, level, color,...
Library "Algebra"
Algebra functions.
line_fromXy(x1, y1, x2, y2)
Get line slope and y-intercept from coordinates
Parameters:
x1 : x coordinate 1 (int - bar index)
y1 : y coordinate 1 (float - price/value)
x2 : x coordinate 2 (int - bar index)
y2 : y coordinate 2 (float - price/value)
Returns: of line
line_getPrice(x, slope,...
Library "intersect"
Find Line Intersection X/Y coordinates.
Simple to use, will find intersection if it exists on the segments
if the line segments do not cross on segment, an 'na' value will be returned
if you plot new items with the output coords, they still plot.
avoid this by setting a na(x) condition before plotting new items
get(l1, l2, (...
Library "BoxLine_Lib"
personal Library for line and box built in functions
lineXY(x)
get x1,y1,x2,y2 in a tuple
Parameters:
x : TODO: line
Returns: tuple of x1,y1,x2,y2
line(x)
Create line with only the y1 value(when line == na) or all
when line != na set x1,y1,x2,y2 individually just 1 or all
- use just the line value to set the x2 to...
Library "regress"
produces the slope (beta), y-intercept (alpha) and coefficient of determination for a linear regression
regress(x, y, len) regress: computes alpha, beta, and r^2 for a linear regression of y on x
Parameters:
x : the explaining (independent) variable
y : the dependent variable
len : use the most recent "len" values of x and...
