请教一下　[金字塔]

请问如何表达下列:

A:=当日开盘后最高价

开空: A-13点时市价开空

或者某K收盘价小于A-12点时市价开空

或者某K最低价小于A-11.4 并且 后5K内有任意1K小于A-11.2时市价开空)

三个条件先成立的实行, 实行后其它两个条件失效

A-13点时市价开空

a-13要等于最新价的意思？

a:=hhv(h,enterbars+1);
variable:n=0;
if (a-13)>=l and (a-13)<=h  and holding=0 then begin
 buyshort(holding=0,1,market);
 n:=1;
end

if l<(a-12) and holding=0 then begin
 buyshort(holding=0,1,market);
 n:=1;
end

if ref(l<(a-11.4),6) and any(l<(a-11.4),5) and holding=0 then begin
 buyshort(holding=0,1,market);
 n:=1;
end

if time=closetime(0) then n:=0;

不好意思,能否讲一下红色部分的具体意思

a:=hhv(h,enterbars+1);
variable:n=0;
if (a-13)>=l and (a-13)<=h  and holding=0 then begin
 buyshort(holding=0,1,market);
 n:=1;
end

if l<(a-12) and holding=0 then begin
 buyshort(holding=0,1,market);
 n:=1;
end

if ref(l<(a-11.4),6) and any(l<(a-11.4),5) and holding=0 then begin
 buyshort(holding=0,1,market);
 n:=1;
end

if time=closetime(0) then n:=0;
