Simple VSA EA needed for analysis in school

 

Hello,

I need a simple EA which incorporates some aspects of volume spread analysis.

If anyone has one (it doesn't need to be anywhere near to perfect, as I only need it for school and it will never see any real money), I would appreciate it if I could get it.

I searched the internet for it, and the only one I found is based on TradeGuider software, but it is not free.
