In this blog, we’ll take a deep dive into the evolution of trading strategies, highlighting key phases, tools, and trends that shaped the way modern portfolios are built and traded today.
🕰️ Phase 1: Manual & Discretionary Trading (2010–2014)

- Day trading and swing trading based on experience and intuition
- Minimal use of automated tools or scripts
- Emotional trading played a large role in decision-making
Limitations:
- Slower execution
- High emotional bias
- Inconsistent results
⚙️ Phase 2: Rise of Technical Automation (2014–2018)

🤖 Phase 3: Algorithmic and Quantitative Trading (2018–2022)

Key Components:
- Quantitative modeling (mean reversion, statistical arbitrage, momentum)

🌐 Phase 4: AI-Powered Decision-Making & Copy Trading (2022–2025)
