z:=y/VOL1*100;
TOSTRING(n,0)+"天机构买入"+TOSTRING(a3,1)+"万手,卖出"+TOSTRING(b3,1)+"万手.净买入"+TOSTRING(y,1)+"万手.占总成交"+TOSTRING(z,1)+"％.";
TOSTRING(n1,0)+"天机构买入"+TOSTRING(a3,1)+"万手,卖出"+TOSTRING(b3,1)+"万手.净买入"+TOSTRING(y,1)+"万手.占总成交"+TOSTRING(z,1)+"％.";

量能指标中青色是主动卖出，白色是被动卖出，粉色是主动买入，粉黄是被动买入，黄柱是净买大于0,绿柱是净买小于0

原主力买卖的一些数据无法正常显示出数值，何解？谢谢！！！！
