Forming a backtest is a skill I’ve spent the past 8 years honing, and after many years of toiling, I share with you some of the secrets I’ve uncovered. Hear the lessons I’ve learned the hard way and the biggest mistakes I see traders and investors make, including experienced ones at banks and hedge funds. This is an easy-to-follow episode that discusses different ways to conduct backtests and the gotchas behind them. I also share a rigorous 10 question check-list I always use when running a new study. This episode is applicable even if you’re a purely discretionary/gut trader as the greatest discretionary traders also rely on historical studies. And if you’re a data scientist, you’ll especially enjoy this episode.
