ALGORITHMIC TRADING
Algorithmic trading,
also known as algo trading, is the use of computer programs to
automate trading strategies based on predefined rules.
1970s – The Birth of Electronic Trading:
- 1970s, stock markets relied on open outcry trading, where traders shouted orders on exchange floors.
- In 1971, the NASDAQ (National Association of Securities Dealers Automated Quotations) became the first electronic stock exchange, allowing computerized trading.
1980s – Rise
of Program Trading:
- The New York Stock Exchange (NYSE) introduced program trading, which allowed institutions to execute large orders using computers.
1990s – High-Frequency Trading (HFT) Begins
- As computing power improved, high-frequency trading (HFT) emerged.
- Traders started using technical indicators,
mathematical models, and automation to execute trades in milliseconds.
- 1998: The U.S. SEC (Securities and Exchange Commission) approved electronic communication networks (ECNs), allowing direct electronic trading without a broker.
2000s – Algo Trading Dominates
- By the early 2000s, algorithmic trading started dominating financial markets.
- The 2008 financial crisis increased scrutiny on algo trading, as automated systems contributed to extreme market fluctuations.
- May 6, 2010: The Flash Crash occurred, where the Dow
Jones Industrial Average dropped nearly 1,000 points in minutes due to
algorithmic trading errors.
- Governments introduced regulations like SEBI's rules in India and Dodd-Frank Act in the US to monitor algo trading.
- AI (Artificial Intelligence) and ML (Machine
Learning) started playing a big role in trading strategies.
2020s – AI, Machine Learning & Retail Algo
Trading
- Today, AI-powered algo trading is growing, using deep learning and big data analytics.
- Retail traders now have access to Python-based algo trading,
APIs (Zerodha, Upstox, etc.), and low-code platforms to automate
strategies.
Conclusion:
- Algo trading has come a long way from simple program trading in the 1980s to AI-driven, high-frequency trading today. With increasing computational power and data-driven strategies, algo trading will continue shaping financial markets in the future.
