Opening Range Breakoutthe first thirty minutes set the day

Evidence: ModerateIntermediateBreakout · Session

The first thirty minutes of a session is the day's only genuine two-sided auction — overnight orders, the open, and everyone who waited for it, all in one window. The high and low of that window are the two levels every intraday trader can see.

The trade is the close beyond one of them, inside a fixed window afterwards. The range locks at the end of the first thirty minutes and does not move again, whatever price does — the rule people break most often.

The evidence here is for what happens when resting orders trigger, not for this way of drawing the level. The level is a choice; the cascade behind it is the mechanism.

Exact rules

Entry

  • Mark the high and low of 13:30–14:00 GMT. Lock them at 14:00.
  • Width filter: the opening range must be narrower than its own 20-day average. A wide opening range means the move already happened in it.
  • Trigger: an M5 close beyond the range high, plus spread. Mirror for the low.
  • Valid window 14:00–17:00 GMT only. No new entry after that.
  • OCO — one side filling cancels the other.

Stop loss

  • The opposite side of the opening range, or 1 × range width, whichever is tighter.
  • If price closes back inside the range, leave. The break has failed and the second attempt is a different trade.
  • Risk 0.5%.

Take profit / exit

  • TP1 = 1 × range width, half the position.
  • TP2 = 2 × range width, or the session close.
  • Flat at the session close. The edge is session-bound, so the position has to be.
