标题：帐户当前资金5o%之内开仓，用哪个函数描述。

 这样做,按照下面例子即可：

buy(1,5%,MARKET),PERTRADER;//表示按照实际资金的5%下单。注意：图表上信号依然还是按照模型资金的百分比计算出来的。但是实际下单时候 会按照账户资金的5%处理。

AA:=TIME>=0930&&TIME<=2400||TIME>=0930&&TIME<1500;

O白:=VALUEWHEN(N1白=1,O),COLORLIGHTGREEN,NODRAW;

N17:=BARSLAST(TIME=0930)+1;

N18:=BARSLAST(TIME=0915)+1;

N19:=IF(N17<N18,N17,N18);

HH1:=REF(HHV(H,N18),N17),NODRAW; 

LL1:=REF(LLV(L,N18),N17),NODRAW; 

N0930每:=BARSLAST(DATE<>REF(DATE,1))+1;

C0930:REF(C,N17),COLORRED,LINETHICK5,NODRAW;//昨天的收盘价

DRAWSL(1,C0930,0,1,0,COLORRED),LINETHICK5;

0930上180:C0930+180,NODRAW,COLORRED;

0930下180:C0930-180,NODRAW,COLORGREEN; 

0930上360:C0930+360,NODRAW,COLORRED;

0930下360:C0930-360,NODRAW,COLORGREEN; 

0930上540:C0930+540,NODRAW,COLORRED;

0930下540:C0930-540,NODRAW,COLORGREEN; 

 

IF(AA,0930上180,NULL),LINETHICK2,COLORRED;//白色加粗

DRAWTEXT(CROSS(AA,0.5),0930上180,'0930上180'),ALIGN1,FONTSIZE20,COLORRED;

DRAWNUMBER1(AA&&REFX(DATE,1)<>DATE||ISLASTBAR,0930上180,0930上180,0),COLORRED;

DRAWTEXT(CROSS(AA,0.5),0930下180,'0930下180'),ALIGN1,FONTSIZE20,COLORGREEN;

DRAWNUMBER1(AA&&REFX(DATE,1)<>DATE||ISLASTBAR,0930下180,0930下180,0),COLORGREEN;

IF(AA,0930上360,NULL),LINETHICK2,COLORRED;//白色加粗

DRAWTEXT(CROSS(AA,0.5),0930上360,'0930上360'),ALIGN1,FONTSIZE20,COLORRED;

IF(AA,0930下360,NULL),LINETHICK2,COLORGREEN;//白色加粗

DRAWTEXT(CROSS(AA,0.5),0930下360,'0930下360'),ALIGN1,FONTSIZE20,COLORGREEN;

DRAWNUMBER1(AA&&REFX(DATE,1)<>DATE||ISLASTBAR,0930下360,0930下360,0),COLORGREEN;

IF(AA,0930上540,NULL),LINETHICK2,COLORRED;//白色加粗

DRAWTEXT(CROSS(AA,0.5),0930上540,'0930上540'),ALIGN1,FONTSIZE20,COLORRED;

DRAWNUMBER1(AA&&REFX(DATE,1)<>DATE||ISLASTBAR,0930下540,0930下540,0),COLORGREEN;

代码不是通用的。

金字塔下相应的函数是DRAWNUMBER  请参考这个函数把上面的DRAWNUMBER1替换下即可。
