空间位置确定示例二

由空间关系确定其关系发生的位置，可以使用BARSLAST函数来实现输出。

留言思路需求是依据5日均线与10均日线的交叉关系，确定该交叉发生的时间位置。本文以MA均线为例做出说明。下图为思路需求示意图：

留言思路示意图

思路步骤：

1. 空间关系使用CROSS函数进行条件表达；
2. 位置确定以BARSLAST函数进行输出。

算法建立：

1.输出两条MA均线

MA5:MA(CLOSE,5),COLORWHITE;

MA10:MA(CLOSE,10),COLORYELLOW;

2. 5日均线向下交叉10均线的位置确定

SCWZ:=CONST(BARSLAST(CROSS(MA10,MA5))),COLORGREEN;

3. 5日均线向上交叉10均线的位置确定

JCWZ:=CONST(BARSLAST(CROSS(MA5,MA10))),COLORRED;

4.交叉位置的标示方法一：垂直线

DRAWSL(CURRBARSCOUNT=SCWZ+1,CLOSE,10000,1024,2),COLORGREEN;

DRAWSL(CURRBARSCOUNT=JCWZ+1,CLOSE,10000,1024,2),COLORRED;

5. 交叉位置的标示方法二：画图标

DRAWICON(CURRBARSCOUNT=SCWZ+1,HIGH*1.003,2);

DRAWICON(CURRBARSCOUNT=JCWZ+1,L,1);

6.输出交叉点处的收盘价格

SCCLOSE:=CONST(REF(CLOSE,SCWZ)),COLORGREEN;

JCCLOSE:=CONST(REF(CLOSE,JCWZ)),COLORRED;

7.跌幅

DF:=IF(SCWZ<JCWZ,(CONST(C)-SCCLOSE)*100/SCCLOSE,DRAWNULL),COLORGREEN;

8.涨幅

ZF:=IF(SCWZ>JCWZ,(CONST(C)-JCCLOSE)*100/JCCLOSE,DRAWNULL),COLORRED;

9.主图标注输出

DRAWTEXT(ISLASTBAR AND DF!=DRAWNULL,H*1.003,STRCAT(‘跌幅 ‘,STRCAT(CON2STR(DF,2),’ %’))),COLORGREEN;

DRAWTEXT(ISLASTBAR AND ZF!=DRAWNULL,L,STRCAT(‘涨幅 ‘,STRCAT(CON2STR(ZF,2),’ %’))),COLORRED;

JCWZ:=CONST(BARSLAST(CROSS(MA5,MA10))),COLORRED;

{DRAWSL(CURRBARSCOUNT=SCWZ+1,CLOSE,10000,1024,2),COLORGREEN};

{DRAWSL(CURRBARSCOUNT=JCWZ+1,CLOSE,10000,1024,2),COLORRED};

DRAWICON(CURRBARSCOUNT=SCWZ+1,HIGH*1.003,2);

DRAWICON(CURRBARSCOUNT=JCWZ+1,L,1);

SCCLOSE:=CONST(REF(CLOSE,SCWZ)),COLORGREEN;

JCCLOSE:=CONST(REF(CLOSE,JCWZ)),COLORRED;

DF:=IF(SCWZ<JCWZ,(CONST(C)-SCCLOSE)*100/SCCLOSE,DRAWNULL),COLORGREEN;

ZF:=IF(SCWZ>JCWZ,(CONST(C)-JCCLOSE)*100/JCCLOSE,DRAWNULL),COLORRED;

DRAWTEXT(ISLASTBAR AND DF!=DRAWNULL,H*1.003,STRCAT(‘跌幅 ‘,STRCAT(CON2STR(DF,2),’ %’))),COLORGREEN;

DRAWTEXT(ISLASTBAR AND ZF!=DRAWNULL,L,STRCAT(‘涨幅 ‘,STRCAT(CON2STR(ZF,2),’ %’))),COLORRED;
