Mql4指示器不会自动更新

如何解决Mql4指示器不会自动更新

我在使用指示器时遇到了一些问题，可以请他人告诉我为什么会导致此问题吗？

简而言之，指标没有刷新

说明： 当我将指标附加到图表上并保持打开状态后，一段时间后，当我将另一个指标相似的实例附加到具有相似参数的目录上时，新指标将显示不同的线，然后是先前附加到图表上的线 即使我不附加新的指标，只需双击当前附加的指标，然后单击“确定”按钮，它就会更改先前绘制的蜡烛的线条 请看截图

有时候变化太多，有时变化不是很多，但是总会有一些变化，这取决于我双击多少条并在指示器上按OK

如果有人能指出我在做什么错，我将非常感激，谢谢

这是我的代码：
