So the Weighted Average Price would be exactly an average price corrected by the Volume, so it's only applicable to an exchange where we know the volumes that were traded for each selection.
The formula is Sum(Price * Volume)/Sum(Volume).
An example:
Odd - Volume
1.52 - 500€
1.45 - 200€
1.56 - 250€
WAP = ((1.52*500) + (1.45*200) + (1.56*250)) / (500+200+250) = 1.516
So if a price has a higher volume it will have a greater importance on the WAP.
