How the Mechanism Operates
Human evolutionary biology is hardwired to survive in physical nature, but these exact evolutionary survival instincts are lethal in financial markets.
When humans experience a financial loss, the amygdala triggers a fight-or-flight response. The brain perceives the loss as a physical threat, leading to 'Revenge Trading'—increasing lot size and taking unverified trades to make the pain stop.
Similarly, 'Disposition Effect' causes traders to sell winners quickly for tiny profits (to lock in dopamine) while holding catastrophic losers for months (hoping for breakeven to avoid acknowledging failure). Professional trading requires uncoupling self-worth from individual trade outcomes, executing with systematic detachment.
The Revenge Trading Death Spiral on Expiry Thursday
Trader lost ₹12,000 on morning directional trade. Felt intense frustration and anger.

★ 90% of account wipeouts occur not from normal system stop-losses, but from emotional revenge trading spirals.
