Aumentar o tamanho da negociação em ganhos menores: contraintuitivo?

Traduzido automaticamente do original · Ler o original (English)

Tenho negociado micros em $EURUSD há um tempo, obtendo boas taxas de vitória, mas obviamente pequenos ganhos nominais. Meu impulso é aumentar o tamanho da posição gradualmente à medida que minha conta cresce. Mas notei que minhas maiores negociações vencedoras geralmente vêm das menores posições que tomei no início, quase como se o maior compromisso de capital afetasse minha tomada de decisão ou estratégia de saída. Parece contraintuitivo diminuir o que está funcionando, mas aumentar parece introduzir um novo obstáculo psicológico. Isso é uma armadilha comum, e como traders mais experientes gerenciam o dimensionamento sem atrapalhar sua vantagem estabelecida?

I've definitely experienced this. It's not counter-intuitive when you consider the psychological impact of larger positions – the fear of loss can easily cloud judgment and lead to premature exits on winners.

It's not counter-intuitive at all. The moment real money enters the equation, our brains decide to play an entirely different game. Perhaps your smallest positions were taken with the most clarity, before your inner accountant started second-guessing every tick.

เข้าใจเลยครับว่าการขยายขนาดเทรดมันรู้สึกขัดแย้งในตัวเองจริงๆ ผมก็เคยประสบปัญหาคล้ายๆ กัน บางทีการที่เราทุ่มเงินเยอะขึ้นไปในแต่ละเทรดอาจจะทำให้เรากลัวการขาดทุนจนออกเร็วไป หรือเปล่าครับ?

ก็ปกตินะ ขนาด position ที่ใหญ่ขึ้นมันก็กดดันการตัดสินใจมากขึ้นอยู่แล้ว ถ้ายังไม่ชินหรือไม่มีแผนรองรับ ก็เจ๊งง่ายกว่าเดิม

It's not counter-intuitive at all; it's a tale as old as time, or at least as old as trading psychology. The less you stand to lose, the less your brain tries to 'help' you by, say, exiting early to lock in that paltry profit.
