测试代码1：

input:xx(13,1,50,1),zz(14,1,50,1);

x:=xx/10;
z:=zz/10;

lc:=ref(c,1);
TR1:=ema(MAX((HIGH-LOW),max(ABS(REF(CLOSE,1)-HIGH),ABS(REF(CLOSE,1)-LOW))),20);
tr2:ref(tr1,1),linethick0;

     sell(holding>0 and close<=hhv(high,enterbars)-z*tr2,0 and c<lc ,0,thisclose);
sellshort(holding<0 and close>llv(low,enterbars)+z*tr2 and c>lc ,0,thisclose);

     buy(holding=0 and vol>=5000 and close>llv(low,exitbars)+x*tr2 and c>lc ,intpart(asset*0.4/close),thisclose);
buyshort(holding=0 and vol>=5000 and close<=hhv(high,exitbars)-x*tr2 and c<lc ,intpart(asset*0.4/close),thisclose);

资产:ASSET,colorgreen,noaxis;
持仓:Holding,linethick0;

 

图表交易代码2：

input:xx(13),zz(14); 

x:=xx/10;
z:=zz/10;

lc:=ref(c,1);
TR1:=ema(MAX((HIGH-LOW),max(ABS(REF(CLOSE,1)-HIGH),ABS(REF(CLOSE,1)-LOW))),20);
tr2:ref(tr1,1),linethick0;

lc:=ref(c,1);

Exitlong:close<hhv(high,enterbars)-z*tr2 and c<lc,Tfilter ;
Exitshort:close>llv(low,enterbars)+z*tr2 and c>lc ,Tfilter;

Enterlong:close>llv(low,exitbars)+x*tr2 and c>lc ,Tfilter;
Entershort:close<hhv(high,exitbars)-x*tr2 and c<lc ,Tfilter;

资产:Tasset,noaxis;
持仓:Tholding,noaxis;

 

 

请教

1：这样的改写是否正确？不正确的话，错在哪里？

2：图表交易空仓是如何显示的？

3：Enter语句不可以模拟测试，在飞狐里是可以的吧？

4：图表交易代码中Tasset 可以读到数据，而Tholding 不可以，bug?

谢谢。
