VOL能量公式的原理是什么？

VAR2:=HIGH-LOW;
VAR3:=ABS(OPEN-CLOSE);
VAR4:=HIGH-IF(CLOSE>OPEN,CLOSE,OPEN);
VAR5:=IF(CLOSE>OPEN,OPEN,CLOSE)-LOW;
VAR6:=VAR3/VAR2*VOL;
VAR7:=VAR4/VAR2*VOL;
VAR8:=VAR5/VAR2*VOL;
VAR9:=IF(VOL/CAPITAL>0.001,1,EXP(ABS(LOG(VOL/CAPITAL*100))));
VARA:=(CLOSE-MA(CLOSE,5))/MA(CLOSE,5)*100;
VARB:=MA(CLOSE,5)>MA(CLOSE,10) AND MA(CLOSE,10)>MA(CLOSE,30) AND MA(CLOSE,30)>MA(CLOSE,60);
VARC:=MA(CLOSE,5)<MA(CLOSE,10) AND MA(CLOSE,10)<MA(CLOSE,30);
多头成交: STICKLINE(CLOSE>MA(CLOSE,30),0,VOL,8,1), , COLORRED;
空头成交: STICKLINE(CLOSE<MA(CLOSE,30),0,VOL,8,1), , COLORGREEN;
向上攻击量: STICKLINE(VAR6>=VAR7 AND VAR6>=VAR8 AND CLOSE>OPEN,0,VAR6,8,0), , COLORRED;
向下攻击量: STICKLINE(VAR6>=VAR7 AND VAR6>=VAR8 AND CLOSE<OPEN,0,VAR6,8,0), , COLORGREEN;
上探量: STICKLINE(VAR7>VAR6 AND VAR7>VAR8,0,VAR7,8,0), , COLORCCCC66;
下探量: STICKLINE(VAR8>VAR6 AND VAR8>VAR7,0,VAR8,8,0), , COLORFF6633;
相对地量: STICKLINE(VAR9>2 AND VOL<MA(VOL,5)/2,0,VOL,2.5,0), , COLORYELLOW;
地量: DRAWTEXT(VAR9>2 AND VOL<MA(VOL,5)/2,VOL,'地量'), , COLORYELLOW;
放量: STICKLINE(VOL>MA(VOL,5)*2.5,0,VOL,2.5,0), , COLORWHITE;
逢高出货: DRAWTEXT(VAR7>VAR6 AND VARA>2 AND VAR7>VAR8 AND CLOSE>MA(CLOSE,5) AND CLOSE>MA(CLOSE,30) AND HIGH>MA(CLOSE,60) AND VOL>MA(VOL,5) AND VAR7>=MA(VOL,5),VOL,'逢高出货'), , COLORGREEN;
逢低跟进: DRAWTEXT(VAR8>VAR6 AND VAR8>VAR7 AND VARA<-2 AND CLOSE<MA(CLOSE,30) AND VAR8<MA(VOL,5)/2 AND MA(VOL,5)<MA(VOL,10),VOL,'逢低跟进'), , COLORMAGENTA;
强势参与: DRAWTEXT(VAR6>MA(VOL,5)*2 AND VAR6>=VAR7 AND VAR6>=VAR8 AND CLOSE>OPEN OR VOL>MA(VOL,5)*3 AND VARB,VOL,'强势参与'), , COLORCC99CC;
空头释放: DRAWTEXT(VAR6>=VAR7 AND VAR6>=VAR8 AND CLOSE<OPEN AND VAR6/VOL>0.7 AND VARC AND VAR6>MA(VOL,5),VAR6*2,'空头释放'), , COLORGREEN;
MA5:MA(VOL,5), , COLORRED;


以上是VOL能量公式的原码。我对公式不是很熟悉，所以想请教各位：
1、其中的“逢低跟进”的原理是什么？
2、我想在飞狐的“指标排序”中排出符合“逢低跟进”条件的股票，应该怎么选择？（在通达信中逢低跟进＝1）。另外可否选出一段时间内符合“逢低跟进”条件的股票？（我想过修改公式，但我不懂编写公式）
对各位高手的帮助，不胜感激！

把“逢低跟进”写作：
逢低跟进:(VAR8>VAR6 AND VAR8>VAR7 AND VARA<-2 AND CLOSE<MA(CLOSE,30) AND VAR8<MA(VOL,5)/2 AND MA(VOL,5)<MA(VOL,10)),LINETHICK,COLORMAGENTA;
DRAWTEXT(逢低跟进,VOL,'逢低跟进'),COLORMAGENTA;

把“逢低跟进”写作：
逢低跟进:(VAR8>VAR6 AND VAR8>VAR7 AND VARA [/quote]


很好用！谢谢！:yes: :cool:
