只偵測第一根5分k是否符合條件的警示

請問以下的警示如何改寫成只偵測第一根5分k是否合乎條件?

謝謝.......

input: Length(15); SetInputName(1, "布林通道天數");

input: BandRange(2);SetInputName(2, "上下寬度");

input: MALength(5);SetInputName(3, "MA天期");

value1 = DirectionMovement(11,value2,value3,value4);   

variable: up(0), down(0), mid(0);

up = bollingerband(Close, Length, BandRange);

down = bollingerband(Close, Length, -1 * BandRange);

var: PV(1);

if CurrentBar = 1 then 

    PV = 1

else

    begin 

        if V > V[1] then

            PV = PV[1] + (Close - Close[1]) / Close[1]

        else

            PV = PV[1];

    end;

if up - down = 0 then value5 = 0 else value5 = (close - down) * 100 / (up - down);

if value2 > 50 and value5 > 30 and (PV-PV[1])/PV[1] > 0.1 and getfield("量比") > 1 then ret=1;
