What is the meaning behind these two functions?
It seems like he is offsetting the volume with the price. But doesn't that result in an information loss, or what exactly is the intended effect?

        protected double vol_weighted_price(cAlgo.API.Collections.IReadonlyList<cAlgo.API.MarketDepthEntry> mkentries)
        {
            double weightdiv = 0.0;
            double tsum = 0.0;
            for (int i = 0; i < mkentries.Count; i++)
            {
                var aent = mkentries[i];
                tsum += (double)aent.Price * (double)aent.Volume;
                weightdiv += (double)aent.Volume;
            }
            if (weightdiv == 0)
            {
                return 0;
            }
            else
            {
                return tsum / weightdiv;
            }
        }


        protected double vol_weighted_cnt(cAlgo.API.Collections.IReadonlyList<cAlgo.API.MarketDepthEntry> mkentries)
        {
            double weightdiv = 0.0;
            double tsum = 0.0;
            for (int i = 0; i < mkentries.Count; i++)
            {
                var aent = mkentries[i];
                tsum += (double)aent.Volume * (double)aent.Price;
                weightdiv += (double)aent.Price;
            }
