0DTE rewards speed of decision and punishes emotional decision. Those are the same skill in opposite directions. The traders who survive build a process that removes the emotional component from execution: a plan written before the open, a checklist before entry, a time stop before the close.
This cluster covers the mindset shifts that matter: process over outcomes, after-action reviews on both winners and losers, and the early-warning signs of revenge trading. None of it is about being a stoic — it is about engineering the environment so emotional choices cost less.
