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

Bookmark this. Image
1) Foundations (1–2 weeks)

Learn these:

1. Python basics → data/ML
2. Pandas (data wrangling)
3. Scikit-learn (ML)
4. SQLAlchemy (DB access) Image
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. Image
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: Image
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 Image
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) Image
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 Image
I have one more thing before you go.

A 23-page research paper reveals the number 1 method Hedge Funds use to beat the market:

Time Series Momentum

This is how: 🧵 Image
1. What Is Time Series Momentum?

Time Series Momentum (TSMOM) bets on trends continuing. If a stock’s up, buy more; if down, sell. A 2011 study of 58 assets proved it works! Image
2. The Data Behind the Strategy

The TSMOM paper analyzed equities, currencies & more. T-stats showed consistent profits across 1-month lookbacks! Image

A Bloomberg Terminal costs $30,000 a year.

Here's how to build 90% of it for free.

Wall Street doesn't advertise this. But every function that matters has a free alternative in Python.

Here's the DIY version (with Python): Image
━━━━━━━━━━━━━━━━━
🔹 REAL-TIME PRICES & CHARTS
━━━━━━━━━━━━━━━━━
Bloomberg: GP
Python: yfinance + Plotly

yfinance pulls live and historical price data for any ticker in seconds. Plotly turns it into interactive charts. Add your own indicators, overlays, and alerts. No subscription needed.
━━━━━━━━━━━━━━━━━
🔹 FINANCIAL STATEMENTS & RATIOS
━━━━━━━━━━━━━━━━━
Bloomberg: FA
Python: yfinance + pandas

yfinance exposes full income statements, balance sheets, and cash flow statements directly. Pull any company's financials into a DataFrame, calculate your own ratios, and build custom models — all in a notebook.

The secret of hedge funds is revealed in a 41-page PDF:

This paper analyzed 464 stocks that 10X-ed over a 24-year period.

Here are the best factors that drive outperformance: (number 3 is the best 🧵) Image
1. Size Effect

"Small-cap stocks outperform medium and large companies in 11 out of 12 cases"

Smaller stocks tend to perform better, but it's not the only contributor. Image
2. Value Effect

"A low book-to-market value (B/M < 1), i.e., low equity and relatively high market cap, implies that investors are paying more for a company than its net assets are worth."

Don't overpay - Overpaying tends to drive underperformance. Image
