價平量穩的語法該怎麼寫?

我自己加了一些條件 , 考考自己

settotalbar(100);

input:SmothN(20,"價格穩定的期數");

input:FluRan(2,"最大震幅%");

var:BigVolume(0);

var:MaxH(0);

var:MinL(0);

BigVolume=highest(v,60);

MaxH=highest(H,SmothN);

MinL=Lowest(L,SmothN);

condition1=trueAll(v<BigVolume*0.5,20);

condition2=((MaxH-MinL)/MaxH*100)<FluRan;

if isLastBar=true then

  begin

    if condition1 

     and condition2 

then

  ret=1;

  end;
