Just been reading about Takashi Kotegawa again and honestly, this guy's story is wild. Started trading back in 2001 during Japan's market chaos with literally just ¥1.6 million (roughly $13k) and turned himself into a legend. Most people would've gotten wiped out in that environment, but not him.

What really stands out about Kotegawa's approach is how disciplined he was. He went all-in on day trading volatile stocks at the Tokyo Stock Exchange, but here's the thing - he never held positions overnight. That's the kind of risk management most retail traders talk about but never actually do. He understood that gap risk could destroy everything, so he just... didn't take it.

The guy's known online as BNF, which comes from a stock code of one of his favorite plays. Fitting for someone who built a fortune by reading price momentum like a book. He wasn't chasing random tickers - he was hunting high liquidity plays with clear directional moves. That's precision trading.

Takashi Kotegawa basically wrote the playbook on what discipline and patience look like in the market. Born in 1978, he started during one of the worst possible times to trade in Japan, yet that's exactly where he learned to thrive. It's a reminder that sometimes the best traders aren't the ones who get lucky - they're the ones who actually know how to manage risk when everything's falling apart.
