Scikit-learn for traditional models (Random Forests, SVM) and Keras or PyTorch for deep learning strategies.
Prioritize capital preservation, strict stop-loss rules, and position sizing over high-yield profit projections.
A strategy is a set of entry and exit rules. Let's start with a classical rule-based strategy before adding ML.

offers a comprehensive REST API with access to global markets and advanced order types.
Testing only on current S&P 500 stocks ignores delisted companies. Solution: Use point-in-time databases.

: Using ATR to set stop distances (e.g., stop at 2×ATR away).
