Initial Balance Breaks

Initial Balance Range Analysis · 09:30 – 10:30 Eastern · n = 2,571 Sessions
The Initial Balance (IB) is defined as the 09:30 – 10:30 ET range (the first hour of the NY equity session). This study examines sessions where the first post-IB bar opens inside the IB range, then tracks how often price breaches the IB high or low by noon (12:00 ET) and by the session close (16:00 ET). A breach is defined as any bar wick trading beyond an IB level by at least 1 tick (0.25 pts). Two confluences are tested for directional edge: where the IB closed relative to its own midpoint, and the order in which the IB high and low were established during the IB window.

Midpoint Confluence
Where did the IB close relative to its own midpoint? A close above the midpoint is associated with higher IB high breach rates; a close below is associated with higher IB low breach rates.

Key Takeaways
IB Almost Always Breaks
96.1% of qualifying days see at least one side breached by the 4pm close. Trading entirely inside a closed IB through the full session is statistically very rare.
High Breaks Dominate
IB High breaches outpace IB Low breaches by ~8pp at both timeframes, consistent with NQ's long-term structural uptrend across the 10-year study window.
Strongest Setup (Bullish)
Close above mid + Low first → 74.0% by noon / 84.0% by close for a high break. Combined, both confluences add ~27pp over the unfiltered high-break baseline.
Strongest Setup (Bearish)
Close below mid + High first → 67.9% by noon / 78.0% by close for a low break. Combined setup adds ~28pp over the unfiltered low-break baseline.
Midpoint Slightly Edges HL Order
Midpoint close location provides marginally more directional edge than HL order alone for high-break identification at noon (70.1% vs 68.2%).
Noon → Close Expansion
Roughly 10–14pp more days register a breach between noon and the 4pm close, indicating continued directional expansion through the afternoon session.
