Why this happens

I do not understand this. There it says that the rate is 1:34 and the red sign warns that the price is volatile.

But even though it says 1:34 it is actually changing to 1:24. It is a difference of 10, which seems important to me, but I don't understand if this is always the case or only when the sign is red? Should I wait for it to remove or remove itself? someone explain to me please
