MetaTrader is one of the most popular retail investing platforms on the planet. Many brokers use it, including IC Markets and Blueberry Markets.For the longest time, programming in MetaTrader was restricted to the MetaQuotes Trading Language — a C++ derivative.

As part of the development, a Cython-based Python Trading library was introduced, enabling everyday scripters to access many of the backend functions that had matured over the years.If you’re looking to use MT5 in your Algorithmic Trading Bot, you’ll need to know how to successfully connect to MT5.I’ll assume that you’ve already figured out a way to safely import the credentials and variables you’ll need, including:Username.
