2 points to clickMeasures price difference, percentage and bar count between two places at once.
What it looks like
The numbered dots are where you click. Once drawn, you can grab those dots and move them.
How to draw it
Drag from one end of the stretch to the other; a box appears with the measured values.
When to use it
It is normally cleared after use — left in place, the chart fills up with numbers.
In SQMATE
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.
