Many people still wonder what EA means and whether it really helps with trading. When talking about Expert Advisor or EA on the MT4 platform, it is a program system that acts as an investment assistant for us, working almost entirely on our behalf.

In the past, investors had to sit in front of the screen all the time, especially when trading FOREX, which is open for trading up to 20 hours a day. The fatigue from watching the screen could lead to incorrect analysis and easy loss of money. Therefore, EA was created.

EA means a computer command system that collects various statistical data and analyzes it to make trading decisions on our behalf. The decisions made by EA are based on statistical data, not emotions or fear like humans do.

The strength of EA is that it doesn’t require us to watch constantly. It can operate 24 hours a day, analyze huge amounts of data quickly, and most importantly, has a STOP LOSS system that limits losses to an acceptable level. When the market moves in an unfavorable direction, EA will immediately close positions to minimize damage.

However, EA also has limitations. First, EA is programmed for specific assets only. You cannot use an EA designed for FOREX to trade gold or oil. Second, EA only follows the preset instructions. If set to sell when profit reaches 6%, EA will sell immediately, even if the market has moved further. Third, EA does not guarantee that we won’t wipe out our account. If EA misreads data or the market suddenly jumps, EA might not be able to close positions in time.

My personal advice is to use EA alongside manual trading. Let EA help generate a basic profit, but we should also have a small portfolio where we trade and monitor ourselves to develop our own experience. What EA still cannot do well is timing when profits increase and deciding to expand positions. EA will stop immediately when it reaches the set point, but we can think critically and make further decisions.
