Average volume

I want to find average volume between two particular dates ,I have these dates in excel for some stocks
can Amibroker get these dates from excel and give average volume between these dates ?
Also can amibroker plot a line form these dates just like fractals.

Example:

ACC 05.08.2013- 09.12.2013- 28.03.2014- 10.04.2014

u will need to look in daily chart and have a look at volume ... and maually calculate avg

any AFL which can read dates in excel and give output in exploration because dates in excel keep changing regularly ?
