New article Create your own Market Watch using the Standard Library Classes is published:

The new MetaTrader 5 client terminal and the MQL5 Language provides new opportunities for presenting visual information to the trader. In this article, we propose a universal and extensible set of classes, which handles all the work of organizing displaying of the arbitrary text information on the chart. The example of Market Watch indicator is presented.

Indicator of the market review

Dima...this is a fine piece of work...thank you for writing these indicators.

I have one problem, though.  When I try to compile MarketWatch.mq5, I get an error that says: "'RefreshSymbolInfo' - cannot call protected member function".

Do you know why I'm getting this error?

Thanks again,

ChuckM

 

Same issue :(

Thank you. The problem is fixed. Please download MarketWatch.mqh again.

You can fix it manually if you replace declaration of RefreshSymbolInfo() to the public section of SymbolWatchDisplay class:

public:
        void            RefreshSymbolInfo();

День добрый!

Отличная работа, немного изменил под себя цвета и строки таблицы, пользуюсь с благодарностью. 

Вопрос по коду если позволите.

Почему средняя за 20 дней считается именно таким образом?

Возможно ответ на поверхности, но я не улавливаю почему не взято обычное среднее арифметическое.

Спасибо!

Good afternoon!

Great work, a little changed under myself colours and rows of the table, use with gratitude.

A question on the code if I may.

Why is the average for 20 days counted in this way?

Perhaps the answer is on the surface, but I do not understand why the usual arithmetic mean is not taken.

Thank you!

Sorry, I figured out that Dima is Russian and as that thread about this article was empty, so I posted it here. 

In fact I am too very doubtful about any response at all as a lot of time has passed since the article was posted.

This leads me to the next thought. Why it is so, that forum doesn't have "notify me by email" feature?

Thank you! 

 
There is no special sense in it - I had an idea to use EMA like it. Now I just use SDD as an arithmetic mean - it is generally accepted and the difference is not significant.
