Discussion of article "Strategy builder based on Merill patterns"

New comment
 

New article Strategy builder based on Merill patterns has been published:

In the previous article, we considered application of Merill patterns to various data, such as to a price value on a currency symbol chart and values of standard MetaTrader 5 indicators: ATR, WPR, CCI, RSI, among others. Now, let us try to create a strategy construction set based on Merill patterns.

As an example, I decided to record a short video, which shows the operation of the strategy builder.

I have unpacked the zip archive and copied all files to their destination.

After compilation, the EA is not loaded and the message appears in the Experts tab of the terminal:

"CElement::CreateCanvas > Failed to create a canvas for drawing the(CButton) control: 4016"

Who has an idea to get the EA to work?

You are probably using build 2280.

There is a bug in the Canvas.mqh.

Remove the following string "(string)CharId + " from line 254.

Then recompile and the error should no longer occur.


Line 254 in Canvas.mqh after the correction:

m_rcname="::"+name+(string)(GetTickCount()+MathRand());

Yes, thank you very much!

I had come to this point in the meantime and had the original line

m_rcname=":: "+name+(string)ChartID()+(string)(GetTickCount()+MathRand());

then to

m_rcname=":: "+name+(string)ChartID();

shortened.

This also works.

In principle, only the generated name is too long.

I don't know whether the random component GetTickCount() is important. Don't try or use all the GFX stuff.

Are you the traderdoc from known forums ?
