How does a trading system work?

The basis for a trading system is a trading platform, which is usually provided free of charge by the broker. One of the most well-known trading platforms is MetaTrader from Metaquotes Software Corporation. MetaTrader has its own scripting language with an associated editor for developing trading systems and indicators. In this case, the trading system functions as an "expert advisor." The trading software analyzes chart movements using indicators and, based on these indicators, identifies trends or developments. Based on the configured trading strategy, parameters, and programmed trading behavior, the trading system makes fully automatic decisions about buying and selling financial assets.
