通達(dá)信軟件，一條5日均線，向上為紅色，向下為藍(lán)色：
長(zhǎng)趨勢(shì)線:MA(CLOSE,5),COLORWHITE,LINETHICK2;
買:IF(長(zhǎng)趨勢(shì)線>REF(長(zhǎng)趨勢(shì)線,1),長(zhǎng)趨勢(shì)線,DRAWNULL),COLORRED,LINETHICK2;
長(zhǎng)平:=IF(長(zhǎng)趨勢(shì)線=REF(長(zhǎng)趨勢(shì)線,1),長(zhǎng)趨勢(shì)線,DRAWNULL),COLOR00FFFF,LINETHICK2;
賣:IF(長(zhǎng)趨勢(shì)線<REF(長(zhǎng)趨勢(shì)線,1),長(zhǎng)趨勢(shì)線,DRAWNULL),COLORBLUE,LINETHICK2;

但該線為一條線，如何畫成每天為一條短線，依次向上或向下。

答：長(zhǎng)趨勢(shì)線:=MA(CLOSE,5);
STICKLINE(長(zhǎng)趨勢(shì)線>REF(長(zhǎng)趨勢(shì)線,1),長(zhǎng)趨勢(shì)線,長(zhǎng)趨勢(shì)線*0.9995,5,0),COLORAA99FF;
STICKLINE(長(zhǎng)趨勢(shì)線<REF(長(zhǎng)趨勢(shì)線,1),長(zhǎng)趨勢(shì)線,長(zhǎng)趨勢(shì)線*0.9995,5,0),COLORFFAA66;
STICKLINE(長(zhǎng)趨勢(shì)線=REF(長(zhǎng)趨勢(shì)線,1),長(zhǎng)趨勢(shì)線,長(zhǎng)趨勢(shì)線*0.9995,5,0),COLOR00FFFF;

或者用下面的試試

長(zhǎng)趨勢(shì)線:=MA(CLOSE,5);

DRAWTEXT(長(zhǎng)趨勢(shì)線>REF(長(zhǎng)趨勢(shì)線,1),長(zhǎng)趨勢(shì)線,'↑'),COLORAA99FF;
DRAWTEXT(長(zhǎng)趨勢(shì)線<REF(長(zhǎng)趨勢(shì)線,1),長(zhǎng)趨勢(shì)線,'↓'),COLORFFAA99;
DRAWTEXT(長(zhǎng)趨勢(shì)線=REF(長(zhǎng)趨勢(shì)線,1),長(zhǎng)趨勢(shì)線,'→'),COLOR00FFFF;

除此以外就不知道"畫成每天為一條短線，依次向上或向下。"是什么意思了
