We have a web application that lists prices of a stocks and we have a requirement to indicate a movement. When there's an increase in price we add an up arrow, where there's a decrease in price we add a down arrow.
My thoughts are that we don't show anything as it's not moving, but I would like to validate this. The options that I see are:
- a thin dash (e.g. -),
- a thick dash (e.g.━),
- a (no change) label following the value
- nothing at all
What is the standard for indicating a values movement?
