单击刷新有时会导致不同的自定义指标结果

Question

我有一个奇怪的现象，我无法弄清楚。我开发了一个自定义指标来计算一个指数，然后我将做出交易决策。该指标使用三个时间段来检查趋势是否稳定。第一个是一分钟，第二个是 5 分钟，最后是 30 分钟。我计算了合适的柱，从中检查较大的时间段，以便它们与一分钟柱相对应。

我的测试表明这些数字计算正确。

此指标附加到一分钟图表。很多时候，我会右键单击并选择刷新，指标会在最后 5 - 10 分钟内发生变化！我找不到它会这样做的原因。我尝试在每分钟栏后单击刷新，有时它会改变，而其他时候则不会。但是，即使我在图表上每分钟点击一次，有时更改也会在 5 到 10 分钟后返回。

你能帮帮我吗？

为了您的帮助，我附上我的代码：

int start()                         // Special function start()
  {
   int i,                        // Bar index                           
       iLook = 0,
       iCurrMinute = 0,
       iMinFloor = 0,
       iMinsAdd = 0,
       Counted_bars,                // Number of counted bars
       iCalcVal,
       iTrendConsistency;

      Trend_Consistency[i]= iTrendConsistency;

      i--;                          // Calculating index of the next bar
     }

ps：boolIncl1Min 始终为 true..

Answer 1

我终于找到了困扰我好几天的答案！ 5 分钟或 30 分钟图表的条件在最近的柱期间发生变化。一分钟条记录每分钟 5 分钟和 30 分钟的情况。如果我点击刷新，过去的柱现在是固定的，因此可以最终计算出来。

如果这些条件发生变化，则需要代码来更新过去的柱状图。

感谢您考虑帮助我。
