A classic example is the intuitive trader who has a keen sense for pattern recognition. After a period of frustration and loss, he begins to overthink his entries and exits, losing a feel for markets. This compounds the losses and turns the normal setback into an outright slump.

Yet another example is the trader whose key strength is risk management and prudence of decision-making. She decides she should be taking more risk and sizes up positions, creating greater volatility of P/L, and destabilizing her emotionally.
