一个布林指标，请高手看下

指标加载后，线过一会就会落后几根K线，如图

请朋友们看下，代码要如何改，才可以一直保持K线出来，指标线就出来呢？

自已顶一下

自已顶一下

真的没有朋友解答一下么？？？

g_ibuf_84 g_ibuf_88 g_ibuf_92 g_ibuf_96 是陣列
直接指定應該會有問題
又將其直接加減乘除 也是會有問題
可能的修改 但不一定正確(g_ibuf_92的計算式未必是這樣):
      g_ibuf_84[i] = iBands(NULL, 0, Periods, Dev, 0, PRICE_CLOSE, MODE_UPPER, i);
       g_ibuf_88[i] = iBands(NULL, 0, Periods, Dev, 0, PRICE_CLOSE, MODE_LOWER, i);
       g_ibuf_96[i] = iBands(NULL, 0, Periods, Dev, 0, PRICE_CLOSE, MODE_MAIN, i);
       g_ibuf_92[i] = (g_ibuf_84[i] - g_ibuf_88[i])/g_ibuf_96[i];

表示 完全看不懂

没看懂  恕无能为力

唉  看不懂

你啊哈 撒发到发生 发生福按时福按时到岗水电费更好都是废话啊但是
