What is the function of Arrow Color in the Buy/Sell Block?

[Smallous]

Hello,

Ref.

.

If I change the Arrow Color it does not appear to have any effect. Anyone know what this is for or when the Color is applied? The Arrow colour appears to be hard coded?

This is the colour of the open trade. If you select any other colour, that buy/sell trade open price will change accordingly.
