Discussion of article "The Indicators of the Micro, Middle and Main Trends"

[MetaQuotes]

New article The Indicators of the Micro, Middle and Main Trends is published:

The aim of this article is to investigate the possibilities of trade automation and the analysis, on the basis of some ideas from a book by James Hyerczyk "Pattern, Price & Time: Using Gann Theory in Trading Systems" in the form of indicators and Expert Advisor. Without claiming to be exhaustive, here we investigate only the Model - the first part of the Gann theory.

I can. The indicator itself exists and builds perfectly well on the chart. Until it comes to calling it from the Expert Advisor.

then only put Print by code and see where it fails.

Look for it. There may be errors in the compiler.

By the way, do you have DLLs allowed?

[egobyk]

Yes, the DLLs are enabled. The problem is in the file GannTrendSignal.mqh, function InitIndicators. this printf was triggered:

        this.handle_main_swing = iCustom( this.m_symbol.Name( ), this.m_period, "GannMainTrend", 1000, false, false, 1, 1, LightCyan, LightGreen, LightPink, LightGreen, LightPink, 3 );
        if( this.handle_main_swing == INVALID_HANDLE )
        {
           printf("INVALID_HANDLE");
                return( false );
        }

this.m_symbol.Name( ), this.m_period

what are equal to ?

this.m_symbol.Name( ), this.m_period

what are equal to ?

USDJPY and PERIOD_H1 respectively.
