About the Author
Kazi Mezanur Rahman is the founder, independent researcher, and editor behind DayTradingToolkit, a one-person publication. He built the site to organize practical trading education, primary-source research, calculators, and documented tool reviews in one place.
Kazi does not present himself as a professional trader, financial adviser, broker, accountant, or attorney. The editorial approach is intentionally conservative: explain risks plainly, disclose affiliate relationships, avoid profit promises, distinguish research from first-hand experience, and correct material errors.
Kazi oversees the site's education library, research methodology, review structure, and content updates across beginner lessons, strategy explainers, psychology guides, calculators, and software comparisons.
