1. A Simple Beginner Strategy (1 day – 1 week)

If the strategy is basic — for example:

• Moving Average Crossover
• RSI-based strategy
• Breakout strategy
• Simple grid bot

Then the development time is short.

Typical timeline:

• 1–3 hours → Coding a basic version in Python
• 1–2 days → Adding backtesting + position sizing
• 2–5 days → Connecting to an exchange API (e.g., Binance)
• 1–2 additional days → Testing on demo/sandbox account

Total: 1 day to 1 week

Beginners may take longer (1–2 weeks), but experienced developers can build these in a day.

2. Intermediate Algorithmic Trading System (2–6 weeks)

These strategies require more components:

• Multi-indicator logic
• Risk management rules
• Logging & error handling
• API rate-limit handling
• Execution engine structure
• Dashboard or alerts
• Database storage

Typical timeline:

• 1–2 weeks → Build and refine the strategy logic
• 1–2 weeks → Create a stable execution engine
• 1–2 weeks → Backtesting, optimising, and testing on live markets

Total: 2 to 6 weeks

This is the level where your bot becomes “professional-grade.”

3. Advanced Quant or AI-Driven Algorithm (2–6 months)

More advanced systems involve:

• Machine learning or deep learning
• Reinforcement learning agents
• Statistical arbitrage (pairs trading, factor models)
• Portfolio optimisation
• Smart order routing
• Low-latency execution
• Real-time data pipelines
• State-of-the-art risk models

Why it takes longer:

• These systems require more complex mathematics
• More rigorous backtesting and simulations
• Significant data cleaning and feature engineering
• Usually built in teams, not solo

Total: 2 months to 6+ months

Large hedge funds spend years refining these models.

4. High-Frequency Trading (HFT) System (6–24 months)

High-frequency trading requires:

• Nanosecond-level latency optimisation
• Co-located servers at the exchange
• Custom C++ or Rust backend
• Proprietary networking architecture
• Order book prediction models
• Hardware optimisation

HFT systems typically require a team of:

• Quant developers
• Network engineers
• Data scientists
• Traders

Total: 6 months to several years
(Not realistic for retail traders.)
