Purpose: The "telegram4mql.dll" file appears to be associated with integrating Telegram functionality into MetaTrader (MQL) based applications. MQL is a programming language used for developing trading strategies, technical indicators, and automated trading systems (Expert Advisors) for the MetaTrader platform.
Functionality: This DLL likely provides a bridge or API for interacting with Telegram's messaging service from within MQL scripts. This could enable traders to receive notifications about trading events (e.g., order executions, price alerts) directly on Telegram or even control their trading accounts through Telegram.
You may be reading this because you discovered telegram4mql.dll in an unexpected location—outside MetaTrader directories, in System32, Temp, or a program files folder you do not recognize. Common user scenarios include:
telegram4mql.dll offers a versatile and efficient way to integrate Telegram with MetaTrader platforms, empowering traders and developers to automate and streamline their trading and communication processes. By understanding and utilizing this DLL, users can unlock new potential in their trading strategies and daily operations.
This report provides an overview of Telegram4MQL.dll, a legacy .NET library designed to bridge MetaTrader (MQL4/MQL5) with the Telegram Messenger API for automated trading alerts and remote management. Overview of Telegram4MQL.dll
Created by developer Steven England around 2016, this DLL (Dynamic Link Library) allows traders to send and receive messages between their trading platform and a Telegram Bot. It was primarily developed to help "spare nerves" by providing real-time updates on order execution and remote system monitoring. Key Features
Two-Way Communication: Not only sends alerts from MT4/5 to Telegram but can also pass commands from a phone back to MetaTrader.
Remote Management: Traders can define custom commands (starting with a /) to perform actions like stopping trades or checking status remotely.
Ease of Integration: Uses a simple implementation style for reading updates via a TelegramGetUpdates function within MQL scripts. Current Status and Critical Issues
As of 2026, several factors limit the reliability of this specific library:
Security Protocol Obsolescence: The original 2016 version faced major issues when Telegram deprecated support for traffic secured by TLS versions lower than 1.2.
Maintenance & Support: Reports from the MQL5 community indicate that the developer’s website has been offline for some time, making it difficult to find official updates or support.
Technical Errors: Users have frequently reported issues such as "TelegramGetUpdates error" or functions missing from the DLL in newer MetaTrader builds. Recommendations and Alternatives
Given the lack of recent updates for the original Telegram4MQL.dll, traders are advised to consider:
Modern MQL-Native Solutions: Many modern implementations, like Alert MT4 to Telegram by RedFox, use MetaTrader’s built-in WebRequest function. This often removes the need for external DLLs entirely, improving platform stability and security.
Updated Libraries: If a DLL is required, look for newer .NET libraries on GitHub that specifically mention TLS 1.2+ compliance to ensure compatibility with Telegram's current API standards.
Telegram FX Copiers: For specialized needs like signal copying, dedicated tools like Telegram FX Copier offer more robust, web-integrated security than a raw DLL.
Without more context, it's difficult to provide a detailed report on "telegram4mql.dll." However, I can offer some general information: telegram4mql.dll

The cursor blinked in the darkness of the room, a rhythmic green pulse against the black background of the MetaEditor. Elias stared at it, his eyes dry and stinging. It was 3:00 AM.
On his desktop, buried in a subfolder named /_dev, sat the file: telegram4mql.dll.
To a casual observer, it was just a library file, a chunk of compiled code. To Elias, it was a loaded gun.
The financial markets were a rigged game; Elias had known that for years. He was a quant, an algorithmic trader who had grown tired of watching his high-frequency strategies bleed out due to latency, or worse, stopped out by invisible market forces. He needed an edge. Not a technical edge—everyone had those—but an information edge.
That was where the .dll came in.
Three months prior, Elias had stumbled upon a glitch in the API of a major financial news aggregator. For exactly 0.4 seconds before a major news headline hit the public terminals, it was accessible via a raw JSON feed that wasn't supposed to exist. It was a ghost signal. The window was too small for a human to read and react to, but perfect for a machine.
He spent weeks writing the bridge. He needed a way to pipe that data instantly into his trading terminal (MetaTrader) without triggering the broker’s latency monitors. He chose Telegram as the relay. It was a messaging app, mundane, used by teenagers and crypto-bros. No firewall flagged it; no broker suspected that a chat app was the trigger for a scalping algorithm.
He had written telegram4mql.dll to act as the translator. It would listen to a specific Telegram channel he controlled, parse the incoming text, and execute a trade on the MQL4 platform before the world even knew the news existed.
It was beautiful. It was illegal. And tonight, he was turning it on.
Elias took a sip of cold coffee. His hand hovered over the 'Compile' button. He had tested it on demo accounts. It worked. It printed money. But the real market was a different beast.
He pressed the key.
The compiler log showed zero errors.
0 errors, 0 warnings, 4 milliseconds.
He dragged the compiled Expert Advisor onto his EURUSD chart. A smiley face appeared in the top right corner of the graph, indicating the robot was active.
Now, the wait.
The Non-Farm Payrolls report was due at 8:30 AM Eastern time. It was the most volatile economic event of the month. A deviation of just 50k jobs could send the dollar skyrocketing or plummeting.
Elias watched the clock on the wall tick slowly. He felt the familiar knot of anxiety in his stomach—the same feeling he used to get when he traded manually, staring at candlesticks until they blurred. But this was different. He wasn't the trader anymore. He was the mechanic.
At 8:29:55 AM, his phone buzzed. A notification from his own private server.
Connection Established.
On his monitor, the telegram4mql.dll log window flickered.
> Init handshake... OK
> Listening on port 443... OK
> Buffering stream...
8:30:00 AM.
In the newsrooms of New York, journalists were just hitting "Publish." In the trading pits, eyes were widening at the numbers.
On Elias’s screen, nothing happened.
He frowned. He looked at the log.
> Packet received.
> Decrypting...
Then, a line of red text he had never seen during testing flashed across the log.
> ERROR: Integrity check failed.
> Source: Unknown.
Elias froze. Unknown? He was the only one with the key. He reached for the keyboard to kill the process, to sever the connection.
Before his fingers touched the keys, the chart exploded.
Not a tick up or down. It was a vertical spike. The price of EURUSD shot up two hundred pips in a single second. What is telegram4mql
Then, his Telegram app opened on its own.
A message appeared in his private channel. It wasn't from his server.
SYSTEM: telegram4mql.dll has been updated.
Elias watched in horror as his terminal executed trades on its own. It bought aggressively, leverages maxing out to 1:500.
SYSTEM: You found the backdoor, Elias. But you didn't build the door. You just walked through it.
The DLL he had written... he hadn't written it alone. He had used an open-source wrapper to handle the encryption. He realized now, with cold, sick clarity, that he had never checked the source code of the wrapper. He had just compiled it.
Someone else had been sleeping in his code. And they had waited for him to turn the key.
The price spiked again. A massive sell-off this time. His account balance, which had been climbing into the six figures, plummeted to zero. Margin call.
The smiley face in the corner of the chart greyed out.
SYSTEM: Thank you for the liquidity.
The terminal closed. The log file wiped itself.
Elias sat in the sudden silence of his apartment. The morning sun was beginning to creep through the blinds, illuminating the dust motes dancing in the air. On his screen, the telegram4mql.dll file remained, innocent and static.
But now, the file size was zero bytes. It had taken everything, and then it had erased itself.
He leaned back, staring at the empty folder. The market continued to roar outside his window, indifferent to the thief who had been robbed.
It is possible your antivirus is wrong, especially if you use:
Before deleting, try temporarily disabling real-time protection, then run the legitimate trading function that requires Telegram. If the DLL works as expected (sends a message, receives a command) and no other symptoms exist, add it to your AV exclusion list after verifying the hash on VirusTotal.
