What is a Trading Advisor (Expert Advisor)?
An Expert Advisor, or also abbreviated as an EA, is an automated program for trading on Forex. The program is a reflection of a certain trading strategy. The Expert Advisor can analyze current market condition, open and close trades and move stop orders. Basically, an Expert advisor can perform any action a trader may need to do for profitable trading. In order to make sure that advisor is trading profitably; you need to test it in the strategy tester. After you have analyzed advisor’s performance and profitability, it is recommended to install the robot on a demo account for some time. When analyzing the Expert advisor’s performance, pay attention to parameters as: profit factor, expected payoff, maximal and relative drawdown, consecutive wins and losses. After you’d installed a robot on a demo account, please take a look how your advisor is working in the real market conditions. If everything works well and your adviser makes profit, you can then switch to a real account.
