在论坛里看到有人想找凹口平量柱的指标公式，刚好我这有，现放上来，以供有需求的朋友使用。

指标里标注的文字，是指形成凹口平量柱的时间
XGX7:ABS((VOL-REF(VOL,7))/REF(VOL,7))<0.04 AND
VOL>1.8*REF(VOL,2) AND
REF(VOL,1) REF(VOL,2) REF(VOL,3) REF(VOL,(7-3)) REF(VOL,(7-2)) REF(VOL,(7-1))

XGX8:ABS((VOL-REF(VOL,8))/REF(VOL,8))<0.04 AND
VOL>1.8*REF(VOL,2) AND
REF(VOL,1) REF(VOL,2) REF(VOL,3) REF(VOL,(8-3)) REF(VOL,(8-2)) REF(VOL,(8-1))

XGX9:ABS((VOL-REF(VOL,9))/REF(VOL,9))<0.04 AND
VOL>1.8*REF(VOL,2) AND
REF(VOL,1) REF(VOL,2) REF(VOL,3) REF(VOL,(9-3)) REF(VOL,(9-2)) REF(VOL,(9-1))

XGX10:ABS((VOL-REF(VOL,10))/REF(VOL,10))<0.04 AND
