Have you read Market Wizards by Jack Schwager? Fantastic book and it really goes deep with how these traders think about approaching and exiting a trade/market.
The problem is it's all hogwash due to survivorship bias; every single one of them could simply be lucky. This is literally no different than interviewing lottery winners and asking them how they chose their numbers. People who write books about the successful are conning you for cash, always. There is nothing to be learned from the habits of just successful people; other than misleading yourself with superstition.
