Introduction

We continue the development of multi-symbol, multi-period indicators which we started in the previous article.

A single-color indicator buffer is a regular double array, which is filled with data when calculating the indicator. We can obtain data from this array and display it on a chart using the CopyBuffer() function provided that the receiving array will be a double array set as an indicator's plotting buffer (SetIndexBuffer()). When copying data from the buffer of the calculated part of the indicator to the buffer of its plotting part, the data is displayed on the chart in one color, which is set for the buffer array of the plotting part. As for multi-colored buffers, the situation is a little different. In addition to the data array, the color buffer also has an array of color indexes.

For one plotted colored indicator line, we can set no more than 64 different colors for its display. You can set the colors for the line using the compiler directive indicator_colorN, for example:

#property indicator_color1  clrGreen,clrRed

or through the PlotIndexSetInteger() function, for example:

PlotIndexSetInteger(0,PLOT_COLOR_INDEXES,2);
PlotIndexSetInteger(0,PLOT_LINE_COLOR,0,clrGreen);
PlotIndexSetInteger(0,PLOT_LINE_COLOR,1,clrRed);

In both cases, here two colors are set for the first plotted line of the indicator: green and red. The green color index is 0, and the red color index is 1. These color indices are stored in a special array of color indices in the indicator's color buffer. For each bar in the timeseries calculated by the indicator, you can set its own color. In this case, a separate color index is set for each bar. In this case it is either 0 or 1. The indicator line is plotted with the color assigned to this index.

It seems that in the examples above, the first method looks more concise. This is true, but in order to be able to dynamically change the color for the indicator line, you need to use the second method: assign the number of colors, and then dynamically change them to any others depending on the situation displayed by the indicator.

For each color buffer, you should assign an array of color indexes, and the array of color indexes must have an index 1 greater than the index of the array being plotted. For drawing styles that require more than one array, the index of the color array is always 1 greater than the index of the last array assigned to plot the line.

Basic principles

Based on the above, we understand that

The indicator plot buffer can use one or more arrays for plotting, depending on the drawing style.
For any color array, one more additional array is used, which is an array of color indexes of the plotting buffer, the index of which is 1 greater than the index of the last array assigned to the plotting buffer.

For a better understanding, let's create a new indicator in which we will indicate several plotting buffers, including simple and colored, using multiple arrays for construction:

We have the following indicator template:

Comments describe which arrays are assigned to certain graphic series. If you create an indicator without changing the default names of graphic series, then the wizard creates quite logical and understandable names for the indicator buffers, where "LabelX" is the name of the buffer being drawn with number X, and "Buffer" is the number of the array (one or more) to construct a graphic series.

For example,

Label5Buffer1 is the first array of the fifth plot buffer (its index is actually 4 since it starts from zero) for constructing a color histogram between two lines.
Label5Buffer2 is the second array of the fifth plot buffer for constructing a color histogram drawn between two lines.
Label5Colors is an array of color indexes of the fifth plot buffer for constructing a color histogram between two lines.

For the example discussed above, the index of the graphic series (plot buffer) is 4, although arrays with indexes 9, 10 and 11 are assigned to it. Therefore, in order to assign any property to this graphic series, you need to set it not by the indexes of the arrays assigned to construct the graphic series, but by the index of the plot buffer which are six in total in this example - from 0 to 5.

To visually observe how properties are assigned to graphic series you can add an input variable, indicate in it the index of the plot buffer which should not be displayed in the data window and set the given plot buffer to the false value:

If you set buffer 0 in the settings, which corresponds to a graphic series named Label1, then this buffer will not be displayed in the data window:

You can see that the data list starts with a buffer named Label2.

If you enter 5 in the indicator settings, the buffer named Label6 will be hidden from the data window:

Accordingly, no matter how many arrays are assigned in the indicator for constructing graphic series, you need to take into account the following factors:

To change the properties of graphic series specifically, you need to access the index of the desired plot buffer, and not the index of the arrays assigned to construct these series.
To construct buffers with different drawing styles, you need one to five arrays assigned as indicator buffers.
All arrays belonging to one plot buffer must appear in strict sequence one after another. They cannot be mixed with other arrays assigned for constructing other graphic series.
The array of color indexes in the list of arrays assigned to one plot buffer is the last one.

Based on the above, we understand that the structure of the buffers of multi-symbol multi-period indicators needs to be improved. Now we will declare five arrays in the structure: four arrays for storing buffer data and a fifth for storing color indexes. Different indicator line drawing styles may require the use of one to five double arrays. All these arrays will be declared in the buffer structure, and only those needed for a specific indicator will be used. Accordingly, when accessing buffer data, you will need to specify, along with the index of this buffer, the number (index) of the required array. It is not very convenient to constantly indicate the index of the required buffer and the index of the required array, since most indicator constructions in standard indicators are made on a single-array buffer, and you will always have to indicate zero as the second index. But later, after creating and testing all the indicators in multi-version forms, we will add methods for obtaining the necessary data from the required buffer and array to the classes of each indicator. This will be done later. For now, let's proceed with the structure of indicator buffers.

Expanding classes

To eliminate the need to keep track of how many arrays the indicator's plot buffer requires for its construction, we will implement the receipt of data from the graphic series in such a way that it is accessed only at the index of the plot buffer and at the index of the desired array. That is, if buffer 0 is drawn on two data arrays and one array of color indexes, then to request data from the first array, you will simply need to specify the index of the plot buffer and the index of the desired array, for example 0 and 0. If we need data from the second array, indicate 0 and 1. To request data from the color buffer, we will create the appropriate methods and will only indicate the index of the plot buffer (0).

This way, we will not need to remember the indexes of the arrays assigned to the indicator buffers. They will be remembered in the class and will return data based on the index of the graphic series and the required array. So, it will probably be a little easier to obtain data by querying it only based on the indexes of plot buffers. A little later, for each class of each standard indicator, we will create methods that return data from the required array. This will further facilitate the task of obtaining data from multi-indicator buffers and plotting their lines on the chart.

All changes will be made to the library file \MQL5\Include\IndMSTF\IndMSTF.mqh.

Also, the structure of the indicator buffer will be redesigned in the library file. We will move some functions to a private section, since access to them from outside is not needed. Previously we initialized and changed the size of only one array, now there will be five of them. Therefore, the initialization and resizing functions now process all five arrays. The required number of arrays will be selected according to the drawing style set for the buffer, since it is the style that determines the required number of arrays for constructing a graphic series. The drawing style is set to the buffer structure when creating the indicator. We will also write the index of the indicator's source array in the buffer structure, so that using this index we can know exactly from which buffer of the source indicator the data is being copied.

Previously, arrays were copied in the Calculate() indicator calculation method. Now, since more than one array will need to be copied, new methods have been created that return the result of copying all arrays used for calculation. In the multi-indicator class, we declare new methods and add the index of the required array to the data retrieval methods.

Here everything is exactly the same as in the method of copying data from a single-color buffer, only an array of color indexes of the plot part is additionally passed to the method, into which we should copy the data of the corresponding array of the calculated part of the indicator. Also, copying is implemented for two arrays: data array and color array.

In all methods that return any properties or data of the specified buffer, the index of the required array is now additionally specified.

Based on the drawing style set for the buffer, we can determine whether the buffer is colored or not, and accordingly use certain methods to draw the buffer. Since we specify the buffer index of the calculation part and write it to the indicator class buffer, it is possible to easily determine from which buffer of the calculation part the data should be copied. Also, if this is a color buffer, then, remembering that the color buffer always comes next to the data buffer of the calculation part, we can know exactly from which buffer we should receive line color data - simply by adding one to the index of the calculation part buffer we can obtain the desired index colors. All this data is already written to the indicator class buffer, which is quite convenient.

In the indicator collection class, we also need to expand existing methods and add new ones.

      ind_obj.SetBufferInitValue(0,EMPTY_VALUE);
     }
//--- Return the handle of the created indicator or INVALID_HANDLE
   return handle;
  }

Such modifications have been made to all similar methods. You can find them in the files attached to the article. Previously, methods simply returned the result of creating and adding an indicator object to the collection list. This was either the handle of the created indicator or INVALID_HANDLE in case of failure. Now, if the indicator object has been successfully created and the pointer to the object in the list is valid, we set Digits and levels for the indicator on the chart and set "empty values" for its buffers to the created indicator object.

All modifications have been made to the library of multi-symbol, multi-period indicators. All changes can be viewed in full in the IndMSTF.mqh file attached to the article.

Testing

In test indicators, we will use the dashboard class Dashboard.mqh, created specifically for testing multi-indicators.

The dashboard class file is attached to the article. It should be located at the path \MQL5\Include\Dashboard\Dashboard.mqh.

In the previous article, we already created a test indicator that draws a multi-symbol multi-period moving average selected in the list. Now, based on this file, we will make some other multi-symbol, multi-period standard indicators, including those with multi-color buffers. The test indicator will draw a line of indicator data from the current symbol and period and a second line from another symbol and period on the same chart. The symbol and period should be selected in indicator settings. The line from the higher timeframe will be thicker.

Some indicators will not look correct when displaying data from different timeframes in one window. For example, some volume indicators display the volume for a selected chart period. On the higher timeframe, the tick volume is definitely higher than on the lower one, and the line from the lower timeframe will be almost straight against the line from the higher one. Therefore, in such indicators only one line will be displayed — the one for the symbol and period selected in the indicator settings.
