Question: how do I put a clean terminal? After all, when I try to reboot, the system automatically recognises me, allowing me to reload the terminal file and saving previously accumulated information: demo account, written indicators, etc. Apparently there is a file among the saved ones that doesn't allow to reload the historical data. :)
 
Hello, my question is whether MT4 EAs will work on this device
 
boris.45:
Simply download again from your broker and put it in a different directory. Enter your demo account username and password manually if you need to, but it's better to open a new one.
And like a newborn baby you will be completely sinless.

Hi. Here's the problem.

The same Expert Advisor trades normally on a demo account and in the tester, but refuses to work or works incorrectly on a real account.

What should I do to fix it?

Miracles do not happen. What brokerage company do you have? Some brokerage companies do not allow you to place market orders if your order contains instructions to set a stop loss and/or take profit. Broco, for example, is like that. There, you have to open a market order first and only after that place stop orders via modification.
 
I specifically ran a test with the parameter x=1, then the parameter x=2, then I optimised x from 1 to 2 step 1. all the checkboxes are off, skipping useless cuts too. the genetic algorithm has been turned on and off. the results are different, helpppp!

I unchecked "skip useless cuts" and the cuts appear. only they differ from a simple test. for example, with the parameter x=1 a simple test results in 500 deals, with x=2 - 700 deals. I should optimise this parameter and x=1 now gets 1 deal, x=2 also gets 1 deal. My Expert Advisor is using virtual graphic modification, is it possible it is that the optimization fails to create a graphic object?

advise what could it be, I have tried it in the tester, orders are opening and closing normally, I have selected the parameter, I have tested all results are rejected, I have manually changed this parameter in the test, all is ok. I have activated the genetic algorithm during optimization and disabled it, changed my settings.
