Week of 22 June 2026: Reading the First Hour

The opening hour sets the tape for the session more often than not. Expiry week or not, the first 60 minutes usually tell you whether the market wants to trend or rotate. Don't commit size before that picture forms.

What to Watch in the Opening Hour

• Gap behaviour vs prior day's range: A gap that holds above the previous day's high (or below the low) and refuses to fill in the first 15–30 minutes typically argues for continuation. A gap that fills inside 30 minutes usually points to a rotation day.
• Open vs pivot: Pull the day's pivot from the pivot calculator before 9:15. Opens above the central pivot with R1 acting as a magnet behave very differently from opens that reject the pivot from above.
• Initial balance width: Measure the high-low of the first hour. If it's noticeably tighter than the average daily range of the past two weeks, expect a breakout later in the session. If it's already wider, the extremes often hold.
• Bank Nifty lead: If banks diverge from the index in the first 30 minutes, fade the weaker side of the pair rather than chase the index direction.

Posture for the Week

Treat the first hour as data collection, not entry. Decide ahead of time which scenario triggers a directional trade and which keeps you in range-fade mode. If the open is mid-range and the first hour stays inside the pivot–R1 or pivot–S1 band, default to mean reversion. A clean break and hold beyond R1 or S1 inside the first hour is the cleaner trend signal.

Stay sized for whichever regime the open hands you.
