Guideline 19. The market can stay irrational much longer than you can stay solvent

Guideline 18

Guideline 20

If you think the market rationally should be going up, but instead it is offering you a strong sell setup, take it. Trade the trade that you have and not the one that you want or expect, because “the market can stay irrational much longer than you can stay solvent” (a quote attributed to John Maynard Keynes).
