Ihor Herasko:
声明数组Bar_data_D1的类型为MqlRates。因此，它将是一维的。或者，如果你认为价差和real_volume字段是不必要的，那就声明你自己的结构而不是MqlRates。

如果你不介意给我一个例子，如何正确书写？

我有一些交易经验，但我正处于学习MQL4的初期。

Tretyakov Rostyslav 2020.12.09 14:19 #14

Dark Kchlyzov:

这么说吧

//--- Min_D_Leve  
 for(int i = 1; 0 <= 1 ;i++)

Tretyakov Rostyslav 2020.12.09 14:47 #15

Dark Kchlyzov:

如果我理解正确，那么

Bar_data_D1 [i][2]

当日低点

Low_D1_Level

前一天的最小值

而如果第一项小于第二项，那么

Min_D_Level = Bar_data_D1 [i][2]

我说对了吗？

前日低点

低于Low_D1_Level的最近的日低点。

Min_D_Level

Dark Kchlyzov 2020.12.09 16:07 #18

2016.12.16线不重画。

因为最近的历史低点是3500巴+-。

当然，这是一个罕见的历史新低，但仍然是。

它应该在这个日期之前通过阵列。
