Expert Advisor (EA)
An Expert Advisor is an automated trading program that runs on MetaTrader platforms, executing trades based on predefined rules without manual intervention.
What it means in practice
An Expert Advisor (EA) is a software program written in MQL4 or MQL5 that runs on the MetaTrader platform. EAs automate trading by executing buy and sell orders based on coded strategies, technical indicators, and risk parameters. Once attached to a chart, an EA monitors the market continuously and places trades without requiring the trader to be present.
EAs range from simple scripts that manage a single indicator-based strategy to complex systems that incorporate multiple timeframes, correlation filters, and dynamic position sizing. Traders can develop their own EAs, purchase them from marketplaces, or hire developers. The quality and profitability of an EA depends entirely on the underlying strategy, not the automation itself.
For forex brokers and introducing brokers, EA traders represent a valuable client segment. Automated systems typically generate higher trading volume than manual traders, which translates to more lot-based commission for IB partners. However, EA traders are also sensitive to execution quality, slippage, and spread conditions, making broker selection critical.
In prop trading, many firms allow EA usage during evaluation phases, though some restrict specific strategies like scalping or high-frequency grid systems. Traders using EAs in prop firm challenges must verify that their automated strategy complies with the firm's risk rules and consistency requirements.
