Initial Balance: The First Hour Framework

The Initial BalanceDefinitionThe price range of the first hour (A + B periods). Narrow IB = trend day. Wide IB = range day. (IB) is the price range established during the first hour of the regular trading session — the A and B periods in Market ProfileDefinitionA chart format using TPO letters to show how long price traded at each level. Reveals the shape of the auction. terms. It is the range where the first wave of institutional orders set the tone for the day.

• IB HighDefinitionHighest price of the Initial Balance. Acts as resistance. A break above = range extension. — the highest price reached during the first hour. Acts as resistance for the rest of the session
• IB LowDefinitionLowest price of the Initial Balance. Acts as support. A break below = range extension. — the lowest price reached during the first hour. Acts as support for the rest of the session
• These two levels are your first reference points every single session
• Many professional traders will not take a directional trade until price breaks the IB HighDefinitionHighest price of the Initial Balance. Acts as resistance. A break above = range extension. or IB Low

The width of the Initial BalanceDefinitionThe price range of the first hour (A + B periods). Narrow IB = trend day. Wide IB = range day. predicts what kind of day is likely:

• Narrow IB — the first hour was tight and compressed. Low conviction from early participants. Expect a range extensionDefinitionWhen price breaks beyond the Initial Balance. If it extends 1x IB range, expect continuation. — one side will break the IB and trend. Narrow IBs produce trend days
• Wide IB — the first hour was volatile and covered a lot of ground. Early participants already committed. Expect rotation — price is more likely to stay inside or near the IB range. Wide IBs produce range days
• Compare the current IB width to the average IB width for that instrument over the past 20 sessions to determine if it is narrow or wide

A range extensionDefinitionWhen price breaks beyond the Initial Balance. If it extends 1x IB range, expect continuation. occurs when price breaks above the IB HighDefinitionHighest price of the Initial Balance. Acts as resistance. A break above = range extension. or below the IB Low:

• One-time framing up — price extends above IB HighDefinitionHighest price of the Initial Balance. Acts as resistance. A break above = range extension. and holds. Bullish signal. Each successive period prints a higher high than the last
• One-time framing down — price extends below IB LowDefinitionLowest price of the Initial Balance. Acts as support. A break below = range extension. and holds. Bearish signal. Each successive period prints a lower low than the last
• The 1x IB rule — measure the width of the IB and add it to the breakout side. If the IB is 20 points and price breaks above IB HighDefinitionHighest price of the Initial Balance. Acts as resistance. A break above = range extension., the first target is IB High + 20 points
• Failed extensions — price breaks the IB but immediately reverses back inside. This is a trap and often leads to a move in the opposite direction

Market ProfileDefinitionA chart format using TPO letters to show how long price traded at each level. Reveals the shape of the auction. practitioners classify days based on how price behaves relative to the IB:

• Normal day — price stays mostly within the IB, small extensions on both sides
• Normal variation — moderate extensions beyond the IB, but the majority of activity stays near the IB range
• Trend day — price breaks the IB in one direction and never looks back. Narrow IB, strong extension, one-time framing
• Double distributionDefinitionPhase 3 of Power of 3. The real move — Smart Money distributes into retail momentum. — price breaks the IB, establishes a new value area, then balances there. Two clusters of activity separated by single printsDefinitionPrice levels with only one TPO letter — price moved through quickly. Often act as support or resistance on retest.
• Neutral day — price extends both above the IB HighDefinitionHighest price of the Initial Balance. Acts as resistance. A break above = range extension. and below the IB Low but closes near the middle. No clear winner
