What Is Algo Trading?
Algorithmic (algo) trading uses pre-programmed instructions to execute orders in financial markets at speeds impossible for manual trading. It relies on algorithms—sets of rules that trigger buy/sell actions when specific market conditions are met. Institutions (hedge funds, AMCs) and increasingly retail investors leverage algo trading for efficiency, precision, and cost reduction.
How Algo Trading Works
- Strategy Development: Define rules (e.g., price thresholds, risk tolerance).
- Algorithm Creation: Code instructions into a trading platform.
- Execution: The algorithm monitors markets and auto-executes orders when criteria align.
Example: A mean-reversion algorithm buys stocks priced below historical averages and sells when prices exceed the average.
