Why initial balance matters

The initial balance is the range set in the first hour, when the most orders hit the market. How the rest of the day treats it tells traders whether it is a range day (price stays inside) or a trend day (price extends far outside).

How traders use it

  • A break and hold above the IB high is read as a trend day up; below the IB low, down.
  • A narrow initial balance often leads to a bigger move later in the day.
  • A break that fails and returns inside often rotates to the other side of the range.

What happened over the last 10 sessions

  • ROK traded above its initial balance on 5 of 10 days and below it on 5; both sides on 1.
  • The average IB range was $7.97.
  • Gap: ROK opened Nov 5 at $402.96, a gap down of 9.2% from $443.88; the gap was not filled.
  • Round numbers nearby: $370.00, $380.00, $390.00.

Combined conditions

  • The 30-minute opening range ($398.75–$412.63) sits inside the first hour. VWAP $391.50.
  • The delayed price is at the bottom 25% of the daily zone: the reversal and breakout setups are both live.

How to trade around ROK's initial balance levels

1. IB breakoutA 5-minute close above $412.63 after 10:30 AM with RVOL above normal is read as a trend day up; back inside cancels it.
2. IB breakdownA close under $398.75 with volume is the breakdown signal; a quick reclaim is a failed break that often rotates to the IB high.
