Buter:
And I'm running terribly slow.

Look at the code of the dll-adapter. there the network is read and reinitialised each time it is accessed! great scope for optimisations.

Yes. And some optimisations can be done by means of the terminal and MQL, if the trading strategy allows it.

For example, for the strategy described in the article, it does not matter at all whether to call the network on every tick or only at the beginning of a bar. Because in its case, the network inputs (and therefore the price forecast) change only when the bar changes.

This strategy can be run in the tester in the "Open prices only" mode. You can also build a filter directly into the Expert Advisor so that the network is used only when a new bar appears.

The tester can be a strategy to drive in the "Only the opening price." And, you can embed directly in the EA filter to the network is used only when a new bar.

But why its so slow that I can't finish a one month testing ! any Ideas.

And now try to imagine if an idea would be a complicated one. :)

Thanks for the cool article! Everything is described well and understandable.

But I have a question: will the adapter file for DDL neural network and MT EA communication work on MetaTrader 4?

Thank you to the author!

Thank you.

For MT4 the adapter should probably be simplified a bit: in MT4, I think, strings in DLL are not transmitted in unicode, but ordinary ones, so you don't need to recode them inside DLL. Everything else should work.

Thank you very much for your reply!

Could you tell me what the problem might be?

I can't create dll. It says: .dll creation failed. I have read in the same programme what can be the reasons of failure. I understood only that visual c++ 6 may be incorrectly configured. Has anyone encountered such a problem with NeuroSolutions? What can I try to change first of all? Should Visual C++ 6 be installed in the Standard installation variant? Do I need to configure it in some way? I have a licensed win 7 64 bit. visual C++ 6 is installed as standard, I tried it, it starts.

When it comes to custom solution wizard, it asks whether to convert the active project or the saved one into a dll. i choose the active one. it offers to save it first, i save it to a separate folder, then i try to create a dll, but it fails. should i save the dll to the folder of the saved project or to any folder?

Regards,

Alexey

I generated DLL on win XP 32 bit. Everything worked there without any settings.

You can also try VC++ of some more recent version. They will surely be better friends with modern operating systems (if this is the problem).

And if you know VC++, I recommend you to look into the build.bat file (it appears in the folder where the DLL should appear). It contains everything you need for "manual" compilation, with the possibility to see all the errors that occur and experiment with the settings.

By the way, using the information from build.bat, you can even try to manually compile the DLL using VC++ Express versions (they are not officially supported by NeuroSolutions).

The article shows that a separate folder is created for DLLs. I also successfully generated DLL in the folder with the project. I.e. you can save it to any folder.

Thank you!

I will try a more recent version of VC++ (by the way, when I installed version 6, I got a window that this version has known compatibility problems with vin 7).

Also, I remembered that I didn't restart my computer after installing VC. Maybe, trivially, that was the reason.

I'll do some magic :)

Thanks a lot for your help! Overall, the idea of the article is very cool. If you want to make several networks for different tools and update them (retrain them) regularly, automatic dll generation looks much more attractive than manual dll creation or writing a network in MQL.
