Start by defining your opening range window, for example the first 5 or 15 minutes after the market opens. Mark the high and low, then wait for a confirmed break with volume before considering an entry.
Your invalidation should sit where the setup is objectively wrong, not where dollar loss feels comfortable. Position size must be adjusted so that a full stop-out still respects your per-trade and daily risk limits.
A trading edge is not just entry quality. It is the combination of setup quality, strict risk control, and the discipline to avoid low-conviction trades.
After each session, log screenshots, execution notes, and emotional state. Over time, your journal reveals which opening-range conditions suit your style and which should be skipped.
