Channel Object
object.channel
Inputs
First anchor Point (the channel start).
Second anchor Point (the channel end).
Third anchor Point (channel width / pitchfork handle).
Outputs
A chart-object sink — it draws on the terminal chart and outputs nothing. Nothing can be wired from it.
Channel Object draws a channel over the anchor points: an equidistant channel or Andrews' pitchfork over three anchors, or a linear-regression / standard-deviation channel over two.
How it works
Wire the anchors: 'point_a' and 'point_b' span the channel; the equidistant channel and pitchfork take 'point_c' for the width or handle. The standard-deviation variant widens by the deviation knob instead. Single placement follows the latest points; stamped leaves one channel per confirmation.
Modes
Mode options
Two parallel rails through the anchors; the third anchor sets the width.
A best-fit line with parallel rails over the two-anchor span.
Regression rails offset by the deviation knob.
Andrews' median line with two tine rails from three pivots.
Placement options
One object per confirmed anchor, oldest removed beyond the cap.
One object that follows the latest confirmed anchor.
Line style options
An unbroken line.
A dashed line. Width above 1 forces solid — a platform rule.
A dotted line. Width above 1 forces solid — a platform rule.
Alternating dashes and dots. Width above 1 forces solid.
A dash followed by two dots. Width above 1 forces solid.
Configuration
Channel family: equidistant channel (3 anchors), linear regression (2), standard deviation (2 + deviation), Andrews' pitchfork (3).
How the object tracks the anchor stream: 'stamped' leaves one object per triggering bar (capped by max_objects); 'single' keeps one object moved in place.
Stamped-placement cap: the oldest object is removed once more than this many are on the chart (FIFO).
