Hello.

Do I need to remove my build 1940 before installing this 2005?
I tried without uninstalling and after install it is same 1940 as before.
Also, I have been unable to update since last year, any reason?
Should I remove all and retry?

Thanks...

It depends on your OS, for example - look at this thread: Support for Windows XP/Windows 2003/Windows Vista to be discontinued after 01 October 2017 

How to update?
Download new MT5 from this site, and/or use updating feature, - look at the image:

Hi Sergey. Thanks for the information.

ok. I have both cases Windows 10 and Windows 7.

I tried to click on that already, nothing happens. I deleted the webinstall contents and reinstalled it.

Same results.

I downloaded from the site, install it and it always appear as build 1940.

I also removed then reinstalled.

I click again and again on the update.

Nothing happens.

It filled the webinstall folder again.

Still no updates. Same 1940.

I did not remove personal data though.

Would this be linked to the broker/server that I am using? I NEED to log to the demo account of yours to perform this update? - Maybe is what I am missing.

Thanks

Oh, it worked now. That was it. I have not understood at first that the update was linked to using a MQ demo account...

Thankx for your support.

Best regards

Lissandro :)

Old versions will work as before.

Support for 32-bit versions ends with the next MetaTrader 5 update

MetaQuotes Software Corp., 2019.11.01 15:07

MetaTrader 5 build 2190 is the last release that supports the 32-bit version. The next official release of the MetaTrader 5 platform will be available only in the 64-bit version. The 64-bit version of Windows XP was released 14 years ago. Support for 32-bit versions currently impedes the development of any project.

Discontinuation of support for 32-bit versions will affect Market as well. After the next official update of the MetaTrader 5 platform, access to the Market will be disabled for the 32-bit version of the terminal. Users will be able to purchase and launch new MetaTrader 5 products from the 64-bit terminal only. All products previously purchased in the 32-bit MetaTrader 5 terminal will continue to work, but it will not be possible to upgrade them to a new version.

The 32-bit version of MetaTrader 5 build 2190 will be available for download and installation for another 6 months

SQLite: Native handling of SQL databases in MQL5 

Contents

• Modern algorithmic trading in MetaTrader 5
  
• Functions for working with databases
• Simple query
  
• Debugging SQL queries in MetaEditor
• Auto reading of query results into the structure using DatabaseReadBind()
• Accelerating transactions by wrapping them into DatabaseTransactionBegin()/DatabaseTransactionCommit() 
• Handling trading history deals
• Portfolio analysis by strategies
• Analyzing deals by symbols
• Analyzing deals by entry hours
• Convenient data output to the EA log in DatabasePrint()  
• Data import/export
• Saving optimization results to the database
• Optimizing query execution using indices

• Integrating database handling into MetaEditor

MQL5 is a perfect solution for algorithmic trading since it is as close to C++ as possible in terms of both syntax and computation speed. The MetaTrader 5 platform offers its users the modern specialized language for developing trading robots and custom indicators allowing them to go beyond simple trading tasks and create analytical systems of any complexity.

In addition to asynchronous trading functions and math libraries, traders also have access to the network functions, importing data to Python, parallel computing in OpenCL, native support for .NET libraries with "smart" function import, integration with MS Visual Studio and data visualization using DirectX. These indispensable tools in the arsenal of modern algorithmic trading currently allow users to solve a variety of tasks without leaving the MetaTrader 5 trading platform.
