How to withdraw money you have earned if you have not deposited it.

How do you withdraw the money you have earned if you haven't deposited it?
I wonder how you made money in the market without an initial deposit
 

Is it possible to parallelize commands in MQL5? For example, to send the execution of a command to another core. In other words, the program will continue to be executed, and a certain function will run in its own context without interfering (taking up time) with the main program. Thank you.

No. Alas, multithreading is not supported by the MQL5 compiler.

Such a task can only be implemented by using a dll.

 

Tried to implement a simple perceptron.

The simplest networks go into a stupor. The problem is in the learning algorithm, but I can't find it.

Can you give me a hint, please?

felidae: I am using my processor resources to do the calculations.
I wonder how it is that you have made money in the market without an initial deposit
 
Why is it that when I have services running the processor is not loaded at all 0% load passes go but slowly in two days of work have earned only 0.01
 

Please tell me please, I have registered and activated a signal on MT4 for some reason it does not work! but on MT4 in the section magazine leaves the following inscription "('3054391': Signal - connect to 78.140.156.176:443 through proxy failed)" what can it be?
