Psychology

Reactor (Archetype)

The trader archetype anchored to feelings and PnL. Identity collapses with the bag — a green day means 'I am a good trader,' a red day means 'I am a bad trader.' Time horizon compresses to the next five minutes. Re-learns the same lesson on a six-week loop indefinitely because there is no record.

Psychology Architect (Archetype) The trader archetype anchored to process and thesis rather than PnL. Identity is separable from any single outcome. The Architect records, reviews, and compounds learning. A bad outcome on a plan-followed trade is variance, not a verdict. → Psychology Disposition Effect The documented investor behavior of selling winners too early and holding losers too long. Named by Shefrin and Statman (1985), confirmed empirically by Odean (1998). The financial-markets fingerprint of loss aversion. Structurally incompatible with memecoin trading, which rewards letting rare winners run. → Psychology Tilt The state in which emotional arousal degrades decision quality below the trader's actual skill floor (Tendler and Carter, The Mental Game of Poker). After a loss, the amygdala spikes, cortisol releases, and prefrontal cortex activity is suppressed. The trader is not running their best setup — they are running a distressed nervous system. →
