求诊断　[金字塔]

VARIABLE:buy1=2,cross1=2;

方向:ma(方向0,3);

//这句的v1>100，好像不起作用？请帮我看一下；
if  v1>100 and 方向>0 and t1 then begin
 buy1:=1;

 buy2:=0;
 end;
 
// if cross(ma(c,5),ma(c,10)) then

// if cross(ma(c,10),ma(c,5)) then
// cross1:=0;
 
 b1:buy1;
 c1:cross1;
 sell(holding>0 and time=closetime(0),0,thisclose);
 sellshort(holding<0 and time=closetime(0),0,thisclose);
 
 sell(buy2=0 and holding>0 and t2,0,thisclose);
 sellshort(buy2=1 and holding<0 and t2,0,thisclose);
 
/买1:buy(buy1 and holding=0 and t1,20%,thisclose);
 买2:buy(buy2 and holding=0 and t2,20%,thisclose);
 
 buyshort(buy1=0 and holding=0 and t1,20%,thisclose);
 buyshort(buy2=0 and holding=0 and t2,20%,thisclose);

比如我加在PTA5分钟K线，虽然我设定v1>100时，buy1=1,但实际是v1<100时，buy1却可能变成1了？谢谢

v1<100，你在哪里进行判断了，赋值语句在哪里？
