I have been coding an indicator to calculate the PIP difference between two lines.
When the indicator is initialized, two lines are drawn on the screen, and a label is set on the lower right corner of the screen, showing the PIP difference between the two lines.
Later when I drag any of the lines, the PIP difference is recalculated. But it only happens when there is a price update on the feed.
How can I make the label refresh as I drag the lines, without having to wait for a feed to update?
