This library is typically used by developers working with MQL4 (MetaQuotes Language 4) to bypass the inherent limitations of MT4's built-in networking functions. By using a DLL, an Expert Advisor (EA) or Indicator can send complex HTTP requests directly to the Telegram Bot API.
Primary Function: Enables MT4 to send text messages, trading alerts, and even chart screenshots to a Telegram chat or channel. Key Components:
DLL File (telegram4mqldll.dll): The core engine that handles the web requests and JSON parsing.
MQL4 Header File (.mqh): A wrapper that defines the functions inside the DLL so they can be called easily within MetaEditor.
Bot API Integration: Requires a unique Bot Token generated via BotFather and a Chat ID for the destination. Typical Use Cases
Trade Alerts: Automatically notifying a user's phone when a specific trade is opened, closed, or hits a Stop Loss/Take Profit.
Signal Providing: Copying trades from an EA to a public or private Telegram channel for subscribers.
Remote Monitoring: Sending periodic reports of account balance, equity, and open positions.
Screenshot Sharing: Capturing the current MT4 chart state and sending it as a .jpg or .png to Telegram for visual confirmation of a setup. Setup and Integration
DLL Permissions: For the library to work, you must enable "Allow DLL imports" in MT4 under Tools > Options > Expert Advisors. Files Placement: Place the .dll file in the MQL4/Libraries folder. Place the .mqh file in the MQL4/Include folder.
Code Implementation: Developers call functions like SendTelegramMessage(string token, string chat_id, string text) within their EA code. Risk and Security Considerations
Users should exercise caution when downloading DLLs from unverified sources, as they can execute arbitrary code on a computer. Similar tools like the Telegram Signal Copier or Alert MT4 to Telegram MQL5 offer verified alternatives for those uncomfortable with manual DLL management.

One notable paper discussing "telegram4mqldll" is a technical study titled "
Algorithmic Trading System: Integrated Trading Using MetaTrader 4 and Telegram Messenger " by Lubis et al. [1].
The paper explores how the Telegram4MQL.dll library serves as a critical bridge between the MetaTrader 4 (MT4) trading platform and the Telegram Bot API. It details the development of an automated notification system that allows traders to receive real-time execution alerts and market updates directly on their mobile devices, bypassing the need to constantly monitor a desktop terminal [1]. Key Insights from the Paper:
Implementation of DLLs: It explains how MT4, which uses the MQL4 language, utilizes external Dynamic Link Libraries (DLLs) like Telegram4MQL.dll to handle complex HTTPS requests that MQL4 cannot natively process efficiently [1].
Real-time Interaction: The research demonstrates a two-way communication flow: the EA (Expert Advisor) sends trade data to the DLL, which then pushes the message to a Telegram Bot [1].
Performance Benefits: The authors highlight that this integration reduces "emotional trading" by providing objective, automated data alerts to the trader's smartphone [1].
