Algorithmic trading (algo trading) is the execution of buy and sell orders by computer programs according to specific rules, without human intervention. Those rules can be based on price, timing, volume or mathematical models.
How Does It Work?
An algorithmic system works in three basic stages: reading data, making a decision and sending the order. The system scans price movements and indicators on the chart in real time, and when a pre-written criterion is met (for example, "buy when the moving averages cross") it sends the trade to the exchange in far less than a second.
What Are the Advantages?
- Emotion-free trading: There is no fear, greed or hesitation. The system simply follows the rules.
- Speed: Orders are placed and closed at a speed no human hand can match.
- 24/7 monitoring: You do not need to sit in front of the screen; the system watches the market continuously.
- Disciplined risk management: Stop-loss and take-profit levels are applied instantly.
MetaTrader 5 (MT5) and Expert Advisors (EAs)
For individual traders, one of the most common ways to trade algorithmically is the MetaTrader 5 (MT5) platform. The bots that run on MT5 are called Expert Advisors (EAs).
With EAs, you can run complex strategies on your own server (VPS) and trade automatically. For example, the Babil34 FX automation software is an Expert Advisor system that applies trend and momentum analysis automatically on MT5.
What Are the Risks?
Algorithmic systems are not a magic wand. A poorly designed strategy can wipe out your account in seconds. Internet outages, VPS failures or sudden price gaps (slippage) can also cause the system to behave incorrectly. That is why sound risk management and continuous supervision are essential.
