Arc

3 points to click

Draws a single curved arc.

What it looks like

The numbered dots are where you click. Once drawn, you can grab those dots and move them.

Set both ends and adjust how much it bows.

Useful for marking a rounded bottom or a rounded top.

What you draw stays

Lines you draw are saved to that symbol's notebook. Open the symbol again and they are still there.

Editable afterwards

Grab the points to move them, and change colour, width and line style. Undo works too.

Shares as drawn

Send the chart as a single link. Whoever opens it sees the same lines.

Drawing tools are a way to organise your thinking. A line you draw does not decide what price will do.
