主题：[求助]请教程序中设定止损的方法。

程序如下：

input: n1(2,1,60),n2(13,1,100),n3(2,2,10),drawdown(3,1,10);

LC := REF(CLOSE,1);
RSI1:=SMA(MAX(CLOSE-LC,0),n1,1)/SMA(ABS(CLOSE-LC),n1,1)*100;
RSI2:=SMA(MAX(CLOSE-LC,0),n2,1)/SMA(ABS(CLOSE-LC),n2,1)*100;
r1:=ema(rsi1,n3);
r2:=ema(rsi2,n3);
r3:(r1-r2),COLORGRAY,LINETHICK0;

ts:=iif(r3>0,1,-1),noaxis;

if holding<>0 then zs:=AVGENTERPRICE-drawdown/100*asset/10/Holding;  //空头是负数，所以能合并

买入价:AVGENTERPRICE,linethick0;
止损:zs,linethick0;

{平多}
sell(holding>0,0,STOP,zs);        //止损价
sell(holding>0 and r3<0,0,thisclose);
{平空}
sellshort(holding<0,0,STOP,zs);    //止损价
sellshort(holding<0 and r3>0,0,thisclose);
{开多}
buy(vol>5000 and holding=0 and r3>0,intpart(asset*0.4/close),thisclose);
{开空}
buyshort(vol>5000 and holding=0 and r3<0,intpart(asset*0.4/close),thisclose);

资产:asset,noaxis,colorgreen;
持仓:holding,noaxis,linethick0;
提示:ts,noaxis,linethick0;

请教

1：我能同时2个Sell指令么？如上，一个是定义止损，一个是正常交易用。

2：在RB02 60min看11/20 15：00 怎么会被平空？最高价是4115，而程序显示止损价是4140，更本没有触及啊

谢谢
