No performance

Hello

Why the robot does not work under the following condition

   protected override void OnTick()
        {
                    if (hivalow.KijunSenMax.Last(0) > hivalow.KijunSenMax.Last(1))
                    ExecuteMarketOrder(TradeType.Buy, Symbol, 10000, "cBotLabel", 20, 20);
        }

Does the robot understand the following values?

if (hivalow.KijunSenMax.Last(0) > hivalow.KijunSenMax.Last(1))

        public int periodMedium { get; set; }

                if (maxmedium < MarketSeries.High[index - i])
