Algorithmic Trading

Financial markets are no longer dominated solely by human decisions. Today, a growing portion of trading is handled by automated trading systems — fast, precise, and emotionless. This is the essence of algorithmic trading, often referred to as algo trading. While the concept might sound complex, it’s more accessible than many assume, even for those without a background in coding or finance.

What Is Algorithmic Trading?

Algorithmic trading is the automated execution of trades on financial markets based on pre-defined rules and logic. In simple terms, a person (or a team of developers) creates a trading bot that determines when to buy and sell assets — all without manual intervention.

These trading algorithms can be built around various parameters, such as:

1. asset prices
2. trading volume
3. technical indicators
4. news sentiment
5. volatility
6. or other market signals.

Once connected to a trading terminal or platform, the bot works in real time, either strictly following preset rules or adjusting dynamically in advanced systems.

How a Trading Algorithm Works

Imagine a trader wants to buy stocks that drop 2% in a day and sell them when they rise 3%. Instead of watching the market all day, they code these rules into a trading robot. The bot monitors price movements 24/7 and automatically executes trades when the set conditions are met.

Key Benefits of Algorithmic Trading

1. Speed: Bots react to market movements in milliseconds, far outpacing human traders.
2. Discipline: Algorithms eliminate emotions such as fear or greed. The system follows logic, not feelings.
3. Scalability: One bot can monitor and trade multiple assets at once — impossible for a human to manage manually.
4. Backtesting: Before going live, the strategy can be tested on historical data to optimize performance.
   

Types of Algo Trading Strategies

There’s no one-size-fits-all in algorithmic trading. Here are the most common algo trading strategies:

1. News-based trading — reacting instantly to market-moving headlines or economic releases.
2. Trend following — entering trades in the direction of the market trend.
3. Scalping — high-frequency trading focused on tiny price moves.
4. Arbitrage — exploiting price differences between exchanges.
5. Market making — placing simultaneous buy and sell orders to profit from the bid-ask spread.

Myths vs. Reality

There’s a common myth that trading bots always win. In reality, bots are tools — not magic solutions. A poorly designed or outdated strategy can lead to consistent losses. Successful algorithmic trading requires continuous monitoring, optimization, and adaptation. It’s not a «set and forget» solution, but a long-term process.
