Bookmap forum

Is there a feature on bookmap that can tell the speed of the stocke price going up ?
for example 2 precentage in one houer 3 precentage in one houer (like in cars this car is driving 50 miles per houer 70 miles per houer )
but in precentage per houer.
is there a feature like that ?

i registrated to the free version but when i open the sotwear it ask me for the licence key 
why is that ?
