Discussion of article "Neural Networks: From Theory to Practice" - page 7

Yedelkin:
Wow... So we're not gonna be able to create a self-learning programme any time soon. Too bad. I'll remain a dummy :)

You can take ready-made developments, they have already been mentioned on the quad forum and here. For example, there is such a header file NeuroNet.mqh, with the help of which you can make an Expert Advisor that learns online and by itself (without the built-in optimiser). Only to start working with such classes, you need to read a couple of articles. The articles have already been published on the quaternary site, you can read them there, not wait for a sequel to be published here.

Thanks for the kick in the right direction!

Guys, is there any recommendations on choosing indicators, frames and pairs for the network? Maybe the author will share his experience?

I have noticed that the price spread has a certain pattern, maybe it can be used in training?

An interesting article Error back propagation algorithm with regularisation in c# has appeared

Why do such errors occur when testing the Expert Advisor from the article?

1. Let's start with which one? There are 2 Expert Advisors in the article: neuro-example.mq5 and macd-neuro-example.mq5.

2. Just downloaded both of them, ran them on the tester from this year, all ticks, EURUSD, MetaQuotes-Demo server - no problems found.

What is the minimum allowable transaction volume on the account?

[Ivan Shibkikh]

I apologise. Indeed, both Expert Advisors from the article work perfectly well. I just wanted to try them so badly that I registered a demo account with the first brokerage company that provides demo-access to MT5. It turned out that I can't open trades of less than 1 lot :(

No. "Excellent work" is when the Expert Advisor sends trade requests taking into account the available limitations for a particular account.

Thanks for the idea. The article has been corrected.
