通达信指标编辑之：变色线形的应用
一，单线变双色
VAR1:MA(C,30),COLORRED;
上升:IF(VAR1>REF(VAR1,1),VAR1,DRAWNULL),COLORRED;
下降:IF(VAR1<REF(VAR1,1),VAR1,DRAWNULL),COLORGREEN;
二，单线变三色
VAR1:MA(C,240),COLORRED;
上升:IF(VAR1>REF(VAR1,1),VAR1,DRAWNULL),COLORRED;
走平:IF(VAR1=REF(VAR1,1),VAR1,DRAWNULL),COLORRED;
下降:IF(VAR1<REF(VAR1,1),VAR1,DRAWNULL),COLORGREEN;
三，技术指标变色
通达信公式中画分段线的方法
例如:kdj分段线源码:
RSV:=(CLOSE-LLV(LOW,9))/(HHV(HIGH,9)-LLV(LOW,9))*100;
K:SMA(RSV,3,1),COLORWHITE;
D:SMA(K,3,1),COLORYELLOW;
J:3*K-2*D,COLORYELLOW;
IF(K<REF(K,1),K,DRAWNULL),COLORGREEN,LINETHICK1;
IF(D<REF(D,1),D,DRAWNULL),COLORGREEN,LINETHICK1;
IF(J<REF(J,1),J,DRAWNULL),COLORFFFF00,LINETHICK1;
IF(K>REF(K,1),K,DRAWNULL),COLORRED,LINETHICK1;
IF(D>REF(D,1),D,DRAWNULL),COLORRED,LINETHICK1;
IF(J>REF(J,1),J,DRAWNULL),COLORFF00FF,LINETHICK1;
四，macd变色
附图公式，变色MacD

STICKLINE(MACD1>MACD2 AND MACD1>0,0,MACD1,1,0),COLORRED;
STICKLINE(MACD1>MACD2 AND MACD1<0,0,MACD1,1,0),COLORGREEN;
STICKLINE(MACD1<MACD2,0,MACD1,1,0),COLORCBCBC0;
STICKLINE(MACD1>=0 OR MACD1<=0,0,0,50,1),COLORWHITE;
DIF:DIF1,COLOR33FF33;
DEA:DEA1,COLORYELLOW;
MACD:MACD1,NODRAW,COLORMAGENTA;

七，变色YJE
AA:=REF(CLOSE,1);

WW:IF(QQ<GG ,SS,MM),LINETHICK1, COLORCYAN;
EE:IF(SS<MM ,GG,QQ),COLORFFFFCC,LINETHICK1;
S:0,COLOR00FFFF;
补充一句：通达信没有飞狐分段画线函数，也没有分析家的条件画线函数，只好用引用函数中的无效数DRAWNULL这个函数。
[DRAWNULL 无效数
返回无效数。
用法： DRAWNULL
例如： IF(CLOSE>REF(CLOSE，1)，CLOSE，DRAWNULL) 表示下跌时分析图上不画线。
