Setting Up the Two-Way Connection
There are two main ways to connect MetaTrader to Telegram: using native MQL code or using a DLL like . Using a DLL offers several advantages:
Fix: Your Bot Token is incorrect or copied poorly. Double-check for missing characters or accidental spaces.
Send commands from your phone via Telegram to the MT4/MT5 platform (e.g., closing all trades). telegram4mqldll
Despite its utility, users have reported several common issues when working with telegram4mqldll. The most frequent problems and their solutions are detailed below.
This article covers the library's role, step-by-step installation, core functions, configuration, troubleshooting common issues, and the successor library MQL.Telegram which replaced it.
Assuming that, the guide should cover installation, configuration, and usage examples. Let me outline the structure: // Ensure "Allow DLL imports" is enabled in
Automatically sends signals from your charts to a private Telegram channel. Remote Control: Send commands from Telegram (e.g., /stopTrades ) to your MetaTrader terminal. Media Sharing:
A user can type /light_on in a Telegram chat. The DLL receives this command via the Telegram API and publishes it to the MQTT broker, which triggers the smart home hub to turn on the lights.
While Telegram4Mql.dll was popular for its simplicity, many modern implementations now prefer using the built-in WebRequest function in MQL. This method does not require external DLLs—improving security and compatibility—but does require adding https://api.telegram.org to the terminal's allowed URL list. Double-check for missing characters or accidental spaces
The mystery surrounding telegram4mqldll remains partially unsolved, as its true purpose and origin continue to elude us. While it's possible that this DLL file is related to a custom or modified version of Telegram, its exact function and safety implications are still unclear. As with any unknown file or executable, it's essential to exercise caution and follow best practices to ensure your system's security and integrity.
Place telegram4mqldll.dll in your MQL4/Libraries or MQL5/Libraries folder.
Native MetaTrader web requests require you to manually add https://telegram.org to the platform's allowed URL list. A DLL bypasses this restriction entirely.
The library operates by acting as a background manager. In the native MQL environment, executing an HTTP request blocks the main thread, which can cause chart lag or missed trade ticks. The DLL bypasses this limitation by handling polling tasks independently and exposing safe functions via an MQL #import directive. Is it working with MT4 ? · Issue #21 · stevenengland/MMM
: 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].
