New MetaTrader 5 Platform Version Build 5640: Dark Theme Improvements and Markdown Support in MetaEditor - page 8

 

I have used metatrader programs for many years, but with the problems of the last two updates, you are really wearing out my patience.

I've tried to find which indicator was causing problems and I can't find it. What I have seen is that even using only the standard indicators, when I open more than one terminal, with clean charts, everything slows down. That is, 5 terminals without indicators, everything goes well, but 4 terminals with clean charts, and only one terminal with indicators (even if they are the standard ones), and the entire system slows down and it is practically impossible to trade

Ok thanks.
 
I'd just like to share my experience with all these updates. Here on Linux, properly configured, it's always worked great. Of course, I replaced the fonts that were causing problems. However, developing such a large software is complicated, but it's also necessary to understand the difficulties of wanting to innovate. I understand the people who found themselves with a system that didn't work as they wanted, as they were used to. Remember, it's for the best; this has a price, always in software. So, thank you, Metaquote. Trust the process. Anyway, MT5 is the best platform for trading and for doing serious things. It wasn't once, but today it is. This is my personal opinion, as I develop software for a living(other things not related to mql5), and I've seen it all. So, thank you!

J'ai cherché l'indicateur problématique, mais sans succès. J'ai constaté que même avec les indicateurs standards, l'ouverture simultanée de plusieurs terminaux sans indicateurs provoque un ralentissement général. En effet, avec cinq terminaux sans indicateurs, tout fonctionne correctement, mais avec quatre terminaux sans indicateurs et un seul terminal avec indicateurs (même standards), le système entier se bloque. Si j'ouvre un deuxième terminal avec indicateurs et les autres sans indicateurs, trader devient pratiquement impossible.

Hello,

I did the same tests as you, and I have exactly the same problem.

 
enum ENUM_PRICE
{
   close,          
};   
double close;
idenfitier 'close' already used Test.mq5 14 8

see declaration of 'ENUM_PRICE::close' Test .mq5 12 4

This didn't happen before.

I think this is most likely due to changes added since build 5200

New MetaTrader 5 Platform Build 5200: Extended OpenBLAS support and enhanced control in MQL5

MetaQuotes, 2025.07.31 14:57

  1. MQL5: Duplicate names within the same scope are now prohibited. For example, it was previously possible to declare an input parameter and a function with the same name within a single file. Such duplication is no longer allowed:
    input int somename=42;
    
    int somename(int x)
      {
       return(42);
      }
  2. MQL5: Identical identifiers are now prohibited across different enumerations. An identifier declared in one enumeration can no longer be reused in another within the same scope:
    enum A
      {
       Value
      };
      
    enum B
      {
       Value  // error, name 'Value' is already used in enumeration A
      };
      
    void OnStart(void)
      {
       enum C
         {
          Value // OK, 'Value' is not used within the OnStart scope
         };
      }
    Matching names can be used in different scopes.

Hello, in Linux versions it’s no longer possible to log in nor browse the market/download something from it. It doesn’t matter which Wine version is used, or whether it’s Gecko/Mono/WebView/Edge. I don’t mean to complain, but this is by far the worst update in a long time.

I have similar issue on Windows, and it was fixed when I installed WebView: post

Develop software for a living & never heard of quality assurance?! Trust the process that is apparently broken? Thank you Metaqoutes, MT5 is the best? Yep.
