初学者的问题 MQL5 MT5 MetaTrader 5 - 页 609

 
Alexander Antoshkin:

我还从例子中提取了按钮的代码,....如何使按钮的按压不固定,即在其功能被执行后,返回到其初始状态。

就按钮而言,这里是帮助中的一个例子。

结转了。

请告知这样的观点。

1.EA+指标正在运行

2.与服务器的连接被断开,所有的指示器渲染都会丢失,它提供的数据仍然存在。

你能建议在哪里读到这方面的信息和/或当连接丢失时会发生什么,为什么绘图丢失,但数据仍然存在。是否有可能再次重画?

提前感谢!

从指标开始--即当 "rate_total "参数为 "0 "时,OnCalculate()中会发生什么。

第一个 rates_total 参数包含指标可用于计算的条数,与图表中的条数相对应。

注意OnCalculate()返回的值和第二个输入参数prev_calculated之间的联系。函数调用中的prev_calculated参数包含了上一次调用时OnCalculate()返回的这允许在计算自定义指标时采用经济的算法,以避免对那些自上次调用此函数以来没有变化的条形图进行重复计算。

为此,通常只需返回rate_total参数的值即可,该参数包含当前函数调用中的条数。如果自上次调用OnCalculate()后,价格数据发生了变化(更深的历史被抽出或历史空白被填补),那么输入参数prev_calculated的值将被终端设置为零。

Karputov Vladimir:

如果是关于按钮,这里有一个帮助中的例子。

注意:按钮1和按钮2是不可锁定的,但按钮3是可锁定的。

这不是一个好例子。

1因为图书馆

2,因为它是由一个小组制作的

3,因为你不了解它。

我画了两个按钮的草图,一个是固定的,另一个需要解锁 - "添加 "需要解锁
