Thanks

Your objective is to be within Target speed +10/-5 or whatever your operator specifies.
Target speed is Vapp + GS mini compensation. Hence your reference is the “magenta” bug (Target speed) on the speed indicator.As long as your indicated airspeed is within the specified margins from the Target Speed your approach is stabilized.
Momentary deviations due to environmental conditions are obviously accepted.

In gusty headwind conditions VTGT will vary all the time, so as long as you are close enough to that speed you are stabilized.
