It is sometimes necessary to display your information as a table or as a set of tabulated lines. There is no problem to simply display several lines in the main window, you should just use Comment(line_1,”\n”,line_2,”\n”…). See example Comment2
However, function Comment () displays information only in the main chart window. But we sometimes may need to show it in an indicator subwindow. In this case, the following example may be useful.

void PrepareInfo(string & array[][])

fills the two-dimensional string array using function MarketInfo(). Then this array is displayed with the function
