Roffild's library - page 7

 

The porting of Alglib to MQL5 is done by MQ themselves.

Alglib in the free version runs in a single thread. From the description, the fixes are mostly for the paid multi-threaded version.

I stopped scaffolding in Alglib because of limitations of the free version. Apache Spark handles scaffolding much faster if the input data doesn't fit in RAM.

Now I'm going back to using neural networks, because I've encountered the insurmountable problem of scaffolding: you can't just tweak the forest without fully generating a new one.

yeah, maybe it's for multithreading... not really clear. Serious libraries yes, no one's disputing that, it's just that it's sometimes more convenient and faster without leaving the cash register (mt5)

 

In the library added work with MLPDataFile from Python.

Я известен сообществу программистов на MQL5 под ником Roffild и это моя библиотека с открытым кодом для MQL5. Попытка реализовать возможности на MQL5, которые уже давно стали стандартом для популярных языков программирования. В каждом файле реализована одна идея. Библиотека пополняется по мере необходимости в новых возможностях. Мало кто...

Who has already tried running Agents on amazon?

Please clarify the situation. The developers said that under Linux you can't run agents as they are essentially Windows services, how did you solve this problem?

And, is it possible to have a GUI to work with so many cores? I'm aiming to run a script on R, it looks reasonable for the money, but it's not clear how to organise it and make it work.

It is possible to run agents under Linux, but it is unlikely they will be paid for providing them to the MQL5 Cloud.

About GUI and R I don't understand at all, because MT5 and its "Agents" tab are used.

I see, Wine is used? I don't know if it's the same for this type of server or if it's possible to use graphical interface to manage the server. Actually I am interested in using these servers for R calculations, so I have more questions, as someone who has understood everything and actually uses this service.

 
Aleksey Vyazmikin:

I see, is Wine being used? Just further somehow you have everything configured without a graphical shell, so the question arises, is this the type of service for this type of server, or can you somehow see a normal "Desktop" and use a graphical shell to manage the server. Actually I am interested in using this server for calculations on R, so I have more questions, as a person who has understood everything and actually uses this service.

I have noticed that wine restricts my work with market and some other services related to terminal-MQL connection (may be it's an IE issue). Everything else works fine. It's even possible to set up requests within a local network, or via a remote URL/IP.

 
Also,is the c4.8xlarge better than thecc2.8xlarge (I couldn't find those, and there's no description on them)?
 
Konstantin Nikitin:

The use of wine has a limitation in the work with the market and some other services related to the work of connecting the MQL account to the terminal (this is my observation, most likely a problem with IE). Everything else works fine. It's even possible to set up requests within a local network, or via a remote URL/IP.

That's good, so I was wrong.

Wine is quite flexible. But not everyone knows how to cook it. It's easier to use a virtual machine
