指标说明：
这是根据三角形面积公式原理计算出多空双方的量进行比较，
粉红色柱表示当天多空相抵的量为正，绿色柱表示为负，
大红虚柱表示累计量在增加，
青色实柱表示累计量在减少，
m20大于m20b表示中线增强，反之为减弱，
当累计量上穿中线m20时，表示新一轮行情在启动

空1:=IF((HIGH-LOW)>0 AND CLOSE>CB, ((HIGH-CLOSE)/(HIGH-CB))*((HIGH-CLOSE)/(HIGH-CB))*((HIGH-CB)/(HIGH-LOW)*VOL),0);
多1:=IF((HIGH-LOW)>0 AND CLOSE>CB, VOL-空1 ,0);
多2:=IF((HIGH-LOW)>0 AND CLOSE<=CB, ((CLOSE-LOW)/(CB-LOW))*((CLOSE-LOW)/(CB-LOW))*((CB-LOW)/(HIGH-LOW)*VOL),0);
空2:=IF((HIGH-LOW)>0 AND CLOSE<=CB, VOL-多2 ,0);
多3:=IF((HIGH-LOW)=0 AND CLOSE>REF(CLOSE,1), VOL,0);
空3:=IF((HIGH-LOW)=0 AND CLOSE<=REF(CLOSE,1), VOL,0);
