Displaying Several CChartObject Objects in a Single Window - script per MetaTrader 5

Description:

Sometimes it is necessary to monitor several charts simultaneously to find correlations between changes in the rates of various currency pairs. This script allows traders to do that displaying several subcharts in a single chart window.

The script has been developed to create charts for the Championship's Minutes at the Automated Trading Championship 2012.

Therefore, it includes:

• Drawing graphical objects in a single window (using CChartObjectSubChart standard class).
  
• Changing graphical objects display settings (background color, scale, grid, scrolling, etc.).
• Graphical object display area shift (using ChartNavigate method, as well as CHART_FIXED_MAX and CHART_FIXED_MIN properties).
• Drawing a rectangle on a graphical object (OBJ_RECTANGLE object).
• Drawing horizontal lines of the average open prices of short and long positions (using OBJ_HLINE).
• Downloading data for the lines from the file (the text file with the data should be placed in terminal_data_folder\MQL5\Files).

CSubChartExtended class derived from CChartObjectSubChart has been developed for drawing subcharts. It is derived from CChartObject class - the basic class for working with graphical objects.
