Discussion of article "MQL5 Cookbook: Monitoring Multiple Time Frames in a Single Window"

When choosing the direction for opening a position, a price chart with multiple time frames displayed at the same time may be quite useful. The MetaTrader 5 Client Terminal provides 21 time frames for analysis. You can take advantage of special chart objects that you can place on the existing chart and set the symbol, time frame and some other properties right there. You can add any number of such chart objects, however it would be quite inconvenient and time-consuming if done manually. On top of that, not all chart properties can be set in manual mode.

In this article, we will take a closer look at such graphical objects. For illustrative purposes, we will create an indicator with controls (buttons) that will allow us to set multiple chart objects in a subwindow at the same time. Furthermore, chart objects will accurately fit in the subwindow and will be automatically adjusted when the main chart or terminal window is resized.

In addition to buttons for adding chart objects, we will also have buttons for enabling/disabling some of the chart properties, including those that can only be modified programmatically.
