主题：[讨论]谁能解释下这开平仓带止损的模型

谁能解释下这开平仓带止损的模型  看不懂怎么开仓的 想套用他的移动止损 我现在的模型有 kd kk  pd pk  怎么套用移动止损呢 

runmode:0;

variable:zs=0,cc=0,hl=0;

ma5:=ma(c,5);

ma20:=ma(c,20);

entertime:=time>100000 and time<144500;

if holding>0 and cc<=0 then sell(1,1,limitr,o);

if holding<0 and cc>=0 then sellshort(1,1,limitr,o);

if holding=0 and cc>0 then buy(1,1,limitr,o);

if holding=0 and cc<0 then buyshort(1,1,limitr,o);

if cc>0 and l<zs then begin

 sell(1,1,limitr,min(o,zs-0.6));

 cc:=0;

end

if cc<0 and h>zs then begin

 sellshort(1,1,limitr,max(o,zs+0.6));

 cc:=0;

end

if cc>0 and ma5<ma20 then cc:=0;

if cc<0 and ma5>ma20 then cc:=0;

if cc=0 and ma5>ma20 and entertime then begin

 cc:=1;

 zs:=c-10;

 hl:=h;

end

if cc=0 and ma5<ma20 and entertime then begin

 cc:=-1;

 zs:=c+10;

 hl:=l;

end

if cc>0 and h>hl then begin//创新高后，上移hl

 hl:=h;

 zs:=hl-10;

end

if cc<0 and l<hl then begin//创新低后，下移hl

 hl:=l;

 zs:=hl+10;

end

if time>=150000 then begin

 cc:=0;

end

if cc>0 and ma5<ma20 then cc:=0;

if cc<0 and ma5>ma20 then cc:=0;

if cc=0 and ma5>ma20 and entertime then begin

 cc:=1;

 zs:=c-10;

 hl:=h;

end

if cc=0 and ma5<ma20 and entertime then begin

 cc:=-1;

 zs:=c+10;

 hl:=l;

end

这部分该如何理解呢
