想知道将来是涨 是跌 就用价格差和价格重心来判断涨跌 【A】价格差:XJ:(2*C+H+L)/4+(2*C-H-L);就是是收盘价与最高最低价的比较.
【B】价格重心;重心:AMOUNT/vol/100;是成交量与成交金额的比较.
我们认为只有今天【A】和【B】的数据两个方面同时大于昨天才有上涨的可能，反之就会下跌，依据这个原理编辑公式如下 【DRAWGBK(XJ>=ref(XJ,1) AND 重心>REF(重心,1),STRIP(RGB(0,0,255),RGB(120,0,120),0))】;
这就是涨跌波段的公式源码，其中参数【K】要根据股性及时改变的以适合构成波段要求. 【请注意】这个公式在横盘阶段不好用 源码 {重心价差}
