乘风对通达信指标写法的一点小技巧（通达信指标公式教程）

通达信画色带，没有飞狐轻松随意方便，一点局限性，就是只能定义AB之间的画色带
DRAWBAND：画出带状线.
用法:DRAWBAND(VAL1,COLOR1,VAL2,COLOR2),当VAL1>VAL2时,在VAL1和VAL2之间填充COLOR1;当VAL1<VAL2时,填充COLOR2,这里的颜色均使用RGB函数计算得到。
例如:DRAWBAND(OPEN,RGB(0,224,224),CLOSE,RGB(255,96,96));

下面我以二条布林线画色带为例子说明一下，正常对MA20与MA60做二条布林画色带

{先隐藏赋值，为了能将你想看到的线型的数据显示在指标的当头位置}
MA20: MA(CLOSE,20),COLORRED,LINETHICK2;
MA60: MA(CLOSE,60),COLORFF0090,LINETHICK2;
UP:MA20+2*STD(CLOSE,20),LINETHICK1,COLOR404080;
DW:MA20-2*STD(CLOSE,20),LINETHICK1,COLORC0C0C0;
UP2:MA60+2*STD(CLOSE,60),LINETHICK1,COLOR808080;
DW2:MA60-2*STD(CLOSE,60),LINETHICK1,COLOR004000;
{然后画色带}
DRAWBAND(MA60,RGB(200,150,30),UP2,RGB(200,150,30));
DRAWBAND(MA60,RGB(100,100,150),DW2,RGB(100,100,150));
DRAWBAND(MA20,RGB(0,50,150),DW,RGB(0,50,150));
DRAWBAND(MA20,RGB(155,50,50),UP,RGB(155,50,50));
{因为画色带遮挡了原来的k线，所以要重做一次k线}
STICKLINE(C>O,H,L,0,0),COLORRED;
STICKLINE(C<=O,H,L,0,0),COLORCYAN;
STICKLINE(C>O,C,O,3.1,1),COLORRED;
STICKLINE(C<=O,C,O,3.1,0),COLORCYAN;
{最后将你想要的赋值的线画出来和变色处理}
MA20,COLOR00FFFF,LINETHICK2;
IF(MA(C,20)<REF(MA(C,20),1),MA(C,20),DRAWNULL),COLOR0B0000,LINETHICK2;
MA60,COLORFF0090,LINETHICK2;
IF(MA(C,60)<REF(MA(C,60),1),MA(C,60),DRAWNULL),COLORFFF000,LINETHICK2;

要解决这个问题，那么我们就变通一下，将指标修改一下
要做一个小限制
IF(A>B,A,B)--就是当A大于B时，显示A，否则显示B

MA20: MA(CLOSE,20),COLORRED,LINETHICK2;
MA60: MA(CLOSE,60),COLORFF0090,LINETHICK2;
UP:MA20+2*STD(CLOSE,20),LINETHICK1,COLOR404080;
DW:MA20-2*STD(CLOSE,20),LINETHICK1,COLORC0C0C0;
UP2:MA60+2*STD(CLOSE,60),LINETHICK1,COLOR808080;
DW2:MA60-2*STD(CLOSE,60),LINETHICK1,COLOR004000;
{然后画色带}
DRAWBAND(MA60,RGB(200,150,30),UP2,RGB(200,150,30));
DRAWBAND(MA60,RGB(100,100,150),DW2,RGB(100,100,150));
DRAWBAND(MA20,RGB(0,50,150),DW,RGB(0,50,150));
DRAWBAND(MA20,RGB(155,50,50),UP,RGB(155,50,50));
{IF(UP>UP2,UP2,UP)就是当UP大于UP2时，显示UP2,否则显示UP}
DRAWBAND(UP,RGB(0,150,50),IF(UP>UP2,UP2,UP),RGB(0,150,50));
DRAWBAND(DW,RGB(0,150,50),IF(DW<DW2,DW2,DW ),RGB(0,150,50));{因为画色带遮挡了原来的k线，所以要重做一次k线}
STICKLINE(C>O,H,L,0,0),COLORRED;
STICKLINE(C<=O,H,L,0,0),COLORCYAN;
STICKLINE(C>O,C,O,3.1,1),COLORRED;
STICKLINE(C<=O,C,O,3.1,0),COLORCYAN;
{最后将你想要的赋值的线画出来和变色处理}
MA20,COLOR00FFFF,LINETHICK2;
IF(MA(C,20)<REF(MA(C,20),1),MA(C,20),DRAWNULL),COLOR0B0000,LINETHICK2;
MA60,COLORFF0090,LINETHICK2;
IF(MA(C,60)<REF(MA(C,60),1),MA(C,60),DRAWNULL),COLORFFF000,LINETHICK2;


第二课，主图叠加指标，先说叠加最高和最低点无法确定的副图指标，这里以叠加MACD为例子

要叠加一个副图，首先要定义副图中心值的位置，然后再作分割处理
{先隐藏赋值，为了能将你想看到的线型的数据显示在指标的当头位置}
MA20: MA(CLOSE,20),COLORRED,LINETHICK2;
MA60: MA(CLOSE,60),COLORFF0090,LINETHICK2;
UP:MA20+2*STD(CLOSE,20),LINETHICK1,COLOR404080;
DW:MA20-2*STD(CLOSE,20),LINETHICK1,COLORC0C0C0;
UP2:MA60+2*STD(CLOSE,60),LINETHICK1,COLOR808080;
DW2:MA60-2*STD(CLOSE,60),LINETHICK1,COLOR004000;
{然后画色带}
DRAWBAND(MA60,RGB(200,150,30),UP2,RGB(200,150,30));
DRAWBAND(MA60,RGB(100,100,150),DW2,RGB(100,100,150));
DRAWBAND(MA20,RGB(0,50,150),DW,RGB(0,50,150));
DRAWBAND(MA20,RGB(155,50,50),UP,RGB(155,50,50));
{IF(UP>UP2,UP2,UP)就是当UP大于UP2时，显示UP2,否则显示UP}
DRAWBAND(UP,RGB(0,150,50),IF(UP>UP2,UP2,UP),RGB(0,150,50));
DRAWBAND(DW,RGB(0,150,50),IF(DW<DW2,DW2,DW ),RGB(0,150,50));
{叠加MACD}
DIFZ:=EMA(C,12)-EMA(C,26);
DEAZ:=EMA(DIFZ,9);
MACDZ:=2*(DIFZ-DEAZ);
HH0:=CONST(HHV(H,120))*1;{以现价的N日最高值为高点，我取120日，这个取值可以根据
自己电脑的版面而定}
LL0:=CONST(LLV(L,120))*1;{以现价的N日最低值为高点}
MM0:=CONST((HH0+LL0)/2);{取中间值}
HL0:=CONST(IF(CONST(C)>=MM0,LL0-(HH0-LL0)*0.2,HH0+(HH0-LL0)*0.2));
{此句为便于叠加副图不影响版面，当现价大于中间值时将叠加副图放在主图上沿反之放下沿
LL0-(HH0-LL0)*0.2是限制副图大小0.2可根据自己的喜好调节}
HH1:=IF(CONST(C)<MM0,HH0,HL0);{再次设定叠加副图的最高值，根据现价与中间值的关系可上可下}
LL1:=IF(CONST(C)>=MM0,LL0,HL0);{再次设定叠加副图的最低值}
HL1:=(HH1+LL1)/2;{最后确定副图的中间值位置}
STICKLINE(MACDZ>0,MACDZ*2+HL1,HL1,1,0),COLOR400080;
STICKLINE(MACDZ>0 AND MACDZ>REF(MACDZ,1),MACDZ*2+HL1,HL1,1,0),COLOR00FFFF;
STICKLINE(MACDZ<0,MACDZ*2+HL1,HL1,1,0),COLOR008080;
STICKLINE(MACDZ<0 AND MACDZ>REF(MACDZ,1),MACDZ*2+HL1,HL1,1,0),COLORC080FF;
(DIFZ*2+HL1),COLORRED;
(DEAZ*2+HL1),COLORFFFFFF;
IF(DIFZ<=REF(DIFZ,1),DIFZ*2+HL1,DRAWNULL),COLORFFF000;
{因为画色带遮挡了原来的k线，所以要重做一次k线}
STICKLINE(C>O,H,L,0,0),COLORRED;
STICKLINE(C<=O,H,L,0,0),COLORCYAN;
STICKLINE(C>O,C,O,3.1,1),COLORRED;
STICKLINE(C<=O,C,O,3.1,0),COLORCYAN;
{最后将你想要的赋值的线画出来和变色处理}
MA20,COLOR00FFFF,LINETHICK2;
