Greed peaks at the top*: when prices have soared and everyone’s winning, greed (and FOMOFollowing the crowd — most dangerous at the extremes.) scream “buy more, don’t miss out!” — right when risk is highest. Fear peaks at the bottom: when prices have crashed and pain is everywhere, fear screams “sell, get out, protect yourself!” — right when opportunity is greatest. So these emotions are perfectly mistimed: they’re strongest precisely when acting on them is most destructive. The legendary advice “be fearful when others are greedy, and greedy when others are fearful” is really an instruction to act against your own emotional grain at the extremes.

The defence is the same theme as the whole track: pre-committed rules and a plan made in a calm state, executed regardless of what fear and greed are screaming in the moment.

FAQs
How do I control fear and greed in the moment?

You can’t eliminate the feelings, but you can *recognise* them (a surge of euphoric must-buy urgency = greed; a wave of panic-sell desperation = fear) and treat them as warning signals rather than instructions. The real control comes *before* the moment: a written plan and pre-set rules (entries, exits, sizing) decided in calm, which you then execute mechanically regardless of what the emotions scream.
