Core Trading Psychology Challenges

• Need extreme discipline to avoid doubling down on losing positions
• Have to fight multiple psychological "demons" specific to each trader

Key Mental Battles

1. Avoiding the Double Down Trap

   • Strong urge to double down when proven wrong
   • Tendency to say "I know I'm right, this is an even better opportunity"
   • Doubling down is "fastest way to go bankrupt"
   • Must fight cognitive desire to avoid admitting mistakes

2. Loss Recognition

   • Need to embrace being wrong daily
   • Must accept when thesis is incorrect
   • Hard to cognitively process frequent losses
   • Dopamine hit from wins makes losses harder to accept

3. Quick Exit Execution

   • Not enough to avoid doubling down
   • Must actively get out before major damage
   • Requires overcoming psychological resistance
   • Need to cut losses early and decisively

• Don't have required psychological preparation

Requirements for Success
