主题：求：大于中间价的多方成交量/真实波幅

或者我这样修改，请校正是否可行？

多方:=c>=o and c>=ref(c,1);

// TR: MAX(MAX((HIGH-LOW),ABS(REF(CLOSE,1)-HIGH)),ABS(REF(CLOSE,1)-LOW));//真实波幅（只求多方）

 中间价:(HHV(HIGH,TODAYBAR)-LLV(LOW,TODAYBAR))/2+LLV(LOW,TODAYBAR);//(日内最高-日内最低）/2+日内最低

aa:if(low>中间价 AND 多方,vol,0);
bb:if(low>中间价 AND 多方,TR,0);
XXXX:sum(aa,TODAYBAR)/sum(bb,TODAYBAR);
