pip difference of the last 5 seconds

hi,

i don't know how to program that:

i want to see the difference in pips of the last 5 seconds.

e.g. if price is now 1.3000 and the price 5 seconds ago was 1.2995, then the difference is 5. this should update every second. does anybody know how to program that with mt4?

thanks a lot!!

Time handling events are not possible in MT4. All actions are driven by ticks and it is impossible to do any accurate time measurements in a predictable manner. I'm not sure that MT5 will do what you want, but it does have time handling events which if properly implemented should be much better than MT4.
