飞机起飞副图指标公式源码（主图指标公式源码）
本文目录一览：
求高手帮忙编写一个选股公式；“通达信”软件用。 要求：“必买”选入； 原副图指标公式源码如下：
RSV:= (((CLOSE - LLV(LOW,9)) / (HHV(HIGH,9) - LLV(LOW,9))) * 100);
K001:=SMA(RSV,3,1);
D001:=SMA(K001,3,1);
J001:=((2.5 * K001) - (3 * D001));
VAR1001:=ZIG(3,14);
VA2001:=EMA(EMA((WINNER(CLOSE) * CLOSE),3),3);
控筹:=(((VA2001 - REF(VA2001,1)) / REF(VA2001,1)) * 1000);
HUOL:= REF(VAR1001,2) REF(VAR1001,1) AND VAR1001 REF(VAR1001,1) AND 控筹 REF(控筹,1) AND J001 REF(J001,1);
准备买:= IF(TROUGHBARS(3,15,1)=0 AND HIGHLOW+0.01,1,-1),COLORYELLOW ,LINETHICK1 ;
必卖: IF(PEAKBARS(3,15,1)=1,1,2),COLORWHITE,LINETHICK1;
必买: REF(准备买, 1) AND HUOL;
{
你提供的公式是可以直接选股的，是很多的人在用的抄底公式（必买），其中用到未来函数，所以，往往买入后买点又消失了，造成了损失。很多人对包含未来函数的公式不敢用。
为此，我将公式又加了一个限制，前一天出现买入（准备买）信号，当天止跌后买入，经过比较长的一段时间的验证，准确率很高，即使买入后又调整了，幅度也非常有限。
选股时： 买入 等于 1

飞机起飞原理
飞机能在空中飞行是因为有一股力量克服重力把飞机托举在空中，我们称这股力为升力。
飞机升力主要由机翼产生。气流流过机翼表面时，在机翼上下表面形成的压力差产生了升力。
