Metatrader has program instructions that can access information about an account through MQL code. It provides a DDL-free way of capturing, recording and communicating information about the user once the code is executed. Once the code is compiled, the malicious instructions are hidden and can not be easily detected.

By way of example, I have written and compiled an indicator that plots a channel. Furthermore, it captures and records user input which is manipulated to a degree before being printed to the 'Experts' tab in the terminal window. The captured input is then piped to a text file in the common folder and saved as 'yourInput.txt'.
