How to Overcome Confirmation Bias: Disprove Your Best Trading Ideas for Success
Disproving your ideas forces you to be objective. It’s like being your own devil’s advocate. If you can’t find any legitimate reason to abandon a particular system after rigorous testing, then it might be as solid as you think. But if there are cracks in the foundation, it’s better to find them now, when the stakes are lower, rather than during a major market drawdown.
When I started trading, I developed a system I was proud of. It performed well in a bull market, and I believed it could weather any storm. But then came the bear market, and I started seeing drawdowns. At first, I dismissed them, chalking it up to temporary volatility. But the losses continued. Finally, I took a step back and realized I had become emotionally attached to a system that wasn’t working in all conditions.
That’s when I learned the value of backtesting across multiple market cycles. My original system wasn’t flawed, but it wasn’t built for every scenario. By trying to disprove its effectiveness, I was able to refine it into something much more reliable.
