Build an End-to-End Python Algorithmic Trading System (complete roadmap + skills + tools)

Bookmark this.

1) Foundations (1–2 weeks)

Learn these:

1. Python basics → data/ML
2. Pandas (data wrangling)
3. Scikit-learn (ML)
4. SQLAlchemy (DB access)

2) Data & Storage (free+paid)

1. Prices: yfinance (free)
2. Fundamentals: FMP (paid)
3. DB: DuckDB (fast, file-based)

Tip: go from raw data ▶ cleaned ▶ features as separate SQL tables.

3) Quant Research Lab

1. Track & compare ideas: MLflow (free)
2. Core playbooks: Momentum, Mean-Reversion, Seasonality
3. Metric stack: Sharpe, Sortino, MaxDD, hit-rate, turnover

Here's what my quant research lab looks like:

4) ML in the Loop (8-step flow)

1. Universe selection
2. Feature engineering (momentum, quality)
3. Time-series CV (no leakage)
4. Model training (XGBoost)
5. Validation (IC, IC-IR, feat importance)
6. Signal creation (scores)
7. Backtest (Zipline/VectorBT)
8. Portfolio analysis

5) Execution & Automation

1. Orchestration: Prefect (free)
2. Broker: IBKR
3. Daily job: fetch → score → allocate → trade → log
4. Guardrails: position limits, slippage, stop rules

I use IBKR + Prefect (Orchestration)

Starter quant stack (copy/paste these tools + skills to replicate a $20,000 terminal):

1. Python, Pandas, Polars, Scikit-learn
2. DuckDB, SQLAlchemy
3. yfinance, FMP
4. MLflow, Prefect
5. IBKR API

I have one more thing before you go.

P.S. - It took me 3 years to become confident in algorithmic trading.

So I spent 100 hours and made a free course to help others.
