Send Notifications: Send trade alerts, daily reports, or screenshots from MT4/MT5 to a private chat, group, or channel.
Remote Commands: Read incoming messages from Telegram (using TelegramGetUpdates) to trigger actions in MetaTrader, such as closing trades or checking account balance.
Ease of Use: It acts as a wrapper, so you don't have to manually manage HTTPS headers or JSON parsing within MQL. Known Technical Status
As of 2026, users should be aware of several critical legacy issues:
TLS Compatibility: Older versions (pre-2019) relied on TLS 1.0/1.1. Telegram now requires TLS 1.2 or higher, which caused the original 2016 version of the DLL to stop working until it was updated.
Project Maintenance: The original developer's website is reportedly offline, and the library is considered "legacy" by some in the community. Many traders have moved to newer alternatives like mql.telegram or native MQL5 WebRequest implementations.
Library Type: It is a .NET DLL. This means you must typically allow "DLL imports" in your MetaTrader settings and ensure you have the appropriate .NET Framework installed on your Windows VPS or PC. Implementation Basics The Telegram4MQL
To use it, you typically place the .dll file in your MQL4/Libraries or MQL5/Libraries folder and import the functions using the #import directive:
#import "Telegram4MQL.dll" string TelegramSendMessage(string token, string chatID, string text); string TelegramGetUpdates(string token, int offset); #import Use code with caution. Copied to clipboard
For more modern alternatives, you can check the MQL5 Market for integrated utilities like MT4 to Tlgrm which provide similar functionality without manual DLL management.
