Summary

Dr. Efrat t Levy is a cybersecurity expert with a PhD in Computer Science and AI from Ben-Gurion University—one of Israel’s top tech institutions. After years studying how to detect hackers through side-channel signals, she applied the same logic to trading. In this conversation, Dr. Levy explains how she uses machine learning to map non-repainting key levels that reveal the hidden order flow—the subtle timing and volume clues that expose the real intent of big players. She shows how correlated markets often move together at these key levels and how that insight helps her trade with precision and low drawdown. We discuss filtering noise, managing psychology, and bridging cybersecurity thinking with market analysis—exploring how data and discipline can uncover the quieter forces shaping market behavior.
