Lines & arrows

A straight line between two points, with an optional head at either end. Press t, then click the start and the end.

One tool covers what used to be two. A trendline is a line with no heads; an arrow is a line with a head at the far end. They were always the same object, so the head is now just another part of the look — like colour or dash — and you set it after drawing rather than by choosing a different tool up front.

Heads

Each end picks its own head, independently:

Head	Reads as
None	a plain line — a trend, a channel edge, a projection
Filled / Open	a pointer: that candle, right there
Bar	the end of a span. A bar at both ends is a measurement: "this move was 400 points"
Dot / Hollow dot	an anchor — this exact price, at this exact candle

Size is one slider shared by both ends, and the head is always drawn in the line's own colour. Two different head styles on one line is normal (a filled tip with a bar tail); two different head sizes or colours is not a thing, deliberately.

Drawing it in

The draw reveal is one of the few that beats a fade: the line grows between its two points at whatever speed you set. Against a chart that is revealing at the same time, it reads as the line being discovered rather than stamped on.

Direction decides where it grows from:

• Normal — start to end.
• Reverse — end back to start.
• Center — outward from the middle to both ends at once. This is the one to use with a bar at each end: a span that grows symmetrically reads as a measurement, while the same span growing left-to-right reads as something pointing right.

A head appears when the drawing reaches its end, so a normal-direction arrow lands its head exactly on arrival. There is no separate setting for it and there does not need to be.

You can see all of this without pressing play: with a line selected, the Animation tab loops its entrance live on the canvas, and the faint dashed path with a chevron shows where the draw starts.

That growth is also what makes a line a good camera target: the camera can follow the growing tip, either as a point or framing everything drawn so far.

Labels

The line can carry a label riding on it. The controls are the ones the text tool uses — typeface, size, weight, an optional background box with its own padding — because they are literally the same fields.

Along position slides the label anywhere between the two ends, which is how you get a label sitting on the line rather than at a corner of it. Set its colour mode to follow the line and it takes the stroke colour automatically.

Look

Stroke colour, width and dash. A dashed line reads as a projection; a solid one reads as a fact. That distinction is worth using consistently across a series of videos.

Pointing without hitting

Stop the tip a little short of the thing it points at. A head that overlaps the candle hides the very shape the viewer is being asked to look at.

Timing

The usual three fields, plus the reveal duration that controls how long the draw takes. A draw spanning about as many candle-widths as the section of chart it covers is the most readable default — it lands exactly as the chart reaches the second point.

Lines with heads are the annotation most worth giving a disappears at: they are loud, they are specific to one moment, and three of them left on screen is noise.
