新文章 DoEasy 函数库中的价格（第六十五部分）：市场深度集合并操控 MQL5.com 信号的类已发布：

在本文中，我将创建所有品种的市场深度集合类，并着手开发创建信号对象类来操控 MQL5.com 信号服务的功能。

我们也在 OnInitDoEasy() 函数中进行一些修改。现在，所有用到品种的即时报价序列创建已实现，可直接访问函数库主对象的相应方法。此外，我还加入了针对所创建 DOM 序列的检查：

//--- Check created timeseries - display descriptions of all created timeseries in the journal
//--- (true - only created ones, false - created and declared ones)
   engine.GetTimeSeriesCollection().PrintShort(false); // Short descriptions

//--- Create tick series of all used symbols
   engine.TickSeriesCreateAll();

//--- Check created tick series - display descriptions of all created tick series in the journal
   engine.GetTickSeriesCollection().Print();

//--- Check created DOM series - display descriptions of all created DOM series in the journal
   engine.GetMBookSeriesCollection().Print();

编译 EA 并启动它，在设置中预先设置两个所用品种，和当前图表周期：

位于所创建 DOM 快照集合上的数据，第一个适配信号的完整数据，以及关于所有盈利的免费信号的简要数据均会被显示到日志里。清单的末尾含有快照序列中的数据，和当前图表的第一个获得的 DOM 快照：
