Introduction If you want to learn algorithmic crypto trading without risking real money, paper trading is the safest, fastest way to start. In this guide, you’ll build a minimal, efficient paper trading loop in Python that runs on your laptop, uses real-time market data, and simulates orders with fees and slippage—no exchange account or API keys required. We’ll use public market data (via CCXT) and a small “paper broker” to track positions, PnL, and trades. ...

Introduction Hash maps are fundamental data structures widely used in programming and system design for their efficient key-value storage and retrieval capabilities. In Python, the built-in dictionary (dict) serves as a highly optimized hash map. However, a linked hash map is a specialized variant that maintains the order of insertion while retaining the fast lookup of a hash map. This blog post explores the concept of linked hash maps in Python, their relevance to system design, and useful resources for deeper understanding. ...
