Key Insight
The open type tells you the starting condition. It does not tell you what will happen next — you need the footprint and structure for that. But it gives you the context to interpret everything else.
Here is a real MNQ chart from March 31 showing this in action. Price opens inside the prior session's Value AreaDefinitionThe price range where 70% of volume traded. Defined by Value Area High (VAH) and Value Area Low (VAL). (the POCDefinitionPoint of Control — the price with the highest volume. Where the most trading happened., VAH, and VAL are all clearly labeled). After balancing near the open, price breaks above the IB HighDefinitionHighest price of the Initial Balance. Acts as resistance. A break above = range extension. and extends to the upside — a textbook open-in-value into IB extension day. Notice how the volume profile confirms heavy participation at the breakout level.

Here is another open-in-value example with a very different outcome. On March 20, MNQ opens inside the prior session's Value AreaDefinitionThe price range where 70% of volume traded. Defined by Value Area High (VAH) and Value Area Low (VAL). and rallies into the prior day's VAH — but gets rejected hard at that level. Price reverses, breaks the IB LowDefinitionLowest price of the Initial Balance. Acts as support. A break below = range extension., and trends down all session. The prior day's VAH acted as a ceiling. When you open inside value and price tests an edge of the prior VA, the reaction at that level tells you everything about the session's direction.

The 80% Rule

- If price opens outside the prior Value AreaDefinitionThe price range where 70% of volume traded. Defined by Value Area High (VAH) and Value Area Low (VAL). and then re-enters it (crosses back through the VAH or VAL), there is roughly an 80% probability that price will travel all the way to the other side of the Value Area
- Example — price opens above the prior VAHDefinitionValue Area High — the upper boundary of the zone where 70% of volume traded., sells off, and drops back inside the VA. The 80% RuleDefinitionIf price opens outside the Value Area but re-enters it, ~80% chance it travels to the other side. says price is likely to reach the VAL
- The logic is based on auction market theory — if the market rejected the extreme and returned to value, it has momentum to travel through the accepted range to test the other side

On March 18, price opens above the prior day's VAHDefinitionValue Area High — the upper boundary of the zone where 70% of volume traded. — outside value. The A and B periods fail to hold above the VAH, and price drops back through it into the value area.

IB Extension Trades
When price breaks the Initial BalanceDefinitionThe price range of the first hour (A + B periods). Narrow IB = trend day. Wide IB = range day., you have a potential trend trade:
- Wait for the IB HighDefinitionHighest price of the Initial Balance. Acts as resistance. A break above = range extension. or IB Low to break
- Confirm with one-time framing — each new period prints a higher high (for longs) or a lower low (for shorts)
- Use IB extension measured-move targets: 1x IB range is the first target, 1.5x is the strong extension target, and 2x is the full trend-day target
- If the IB was narrow, expect a larger extension — narrow IBs produce the best trend days. A narrow IB that breaks one side often reaches 1.5x to 2x
- Confirm with deltaDefinitionAsk volume minus bid volume. Positive = more buying. Negative = more selling. Shows who is more aggressive. — rising cumulative deltaDefinitionRunning total of buying vs selling across the session. Shows who has been in control overall. on a long extension, falling on a short extension
- Failed extension — if price breaks the IB but immediately reverses back inside within the same period, it is a trap. Look for a rotation to the opposite side of the IB
Here is a real NQ 5-minute chart showing this concept in action. Notice how the IB LowDefinitionLowest price of the Initial Balance. Acts as support. A break below = range extension. (marked by the blue horizontal zone) acts as support after the initial balance is established. Price bounces cleanly off the IB Low level, and the volume profile on the left confirms heavy volume was traded at that zone — creating a strong floor. The volume profile POCDefinitionPoint of Control — the price with the highest volume. Where the most trading happened. sits right at the IB Low, reinforcing it as a key level.

Poor High and Poor Low Retests
Poor highsDefinitionProfile high with multiple TPOs but no single-print tail. Auction incomplete — price tends to revisit. and poor lows from prior sessions are unfinished auctions waiting to be completed:

The next session opens below the prior VA and trends down — when price reaches the single print zone, it moves through quickly because that zone was never accepted as value. The indicator highlights single print zones automatically so you can see exactly where these initiative levels are.

Spike Rules
A spike occurs when price makes a dramatic move in the final one or two periods of the session — a late-day rally or selloff that creates single printsDefinitionPrice levels with only one TPO letter — price moved through quickly. Often act as support or resistance on retest. at the extreme. The spike is significant because it happened late, meaning traders had to make a decision overnight about whether those prices are accepted or rejected.
The spike high and the spike base are the two key reference levels for the next session:
- Open above spike high — acceptance of spike prices. Buyers committed overnight. The spike base becomes support. Expect continuation higher. Buy pullbacks to the spike high
- Open within the spike range — undecided. Watch which side price breaks (spike high or spike base) to determine direction. Let the market reveal its hand first
- Open below spike base — rejection of spike prices. The late-day move was emotional, not substantive. Buyers who entered during the spike are trapped. Expect selling as they liquidate. Sell rallies back to the spike base
Key Insight
Spikes are the market's overnight homework assignment. Where price opens the next day relative to the spike tells you whether the market accepted or rejected the late-session move — and that single data point gives you a high-probability directional bias.
Responsive vs Initiative Activity
Understanding whether activity at a given price is responsive or initiative is fundamental to reading auction markets. It determines whether to fade a move or follow it.
- Responsive buying — buying below the Value AreaDefinitionThe price range where 70% of volume traded. Defined by Value Area High (VAH) and Value Area Low (VAL).. This is expected. Prices are cheap relative to accepted value. Responsive buying maintains the current range and tends to push price back toward the POCDefinitionPoint of Control — the price with the highest volume. Where the most trading happened.
- Responsive selling — selling above the Value AreaDefinitionThe price range where 70% of volume traded. Defined by Value Area High (VAH) and Value Area Low (VAL).. This is expected. Prices are expensive. Responsive selling caps rallies and pushes price back toward the POCDefinitionPoint of Control — the price with the highest volume. Where the most trading happened.
- Initiative buying — buying at or above the Value AreaDefinitionThe price range where 70% of volume traded. Defined by Value Area High (VAH) and Value Area Low (VAL).. This is unexpected. Buyers are aggressively seeking higher prices and pushing for new value. Initiative buying breaks balance and creates new higher value areas
- Initiative selling — selling at or below the Value AreaDefinitionThe price range where 70% of volume traded. Defined by Value Area High (VAH) and Value Area Low (VAL).. This is unexpected. Sellers are aggressively forcing lower prices. Initiative selling breaks balance and creates new lower value areas
The key question at any level is: is this activity expected or unexpected at this price?
- Expected activity (responsive) → fade it. Trade back toward the POCDefinitionPoint of Control — the price with the highest volume. Where the most trading happened.
- Unexpected activity (initiative) → follow it. New value is being created
Key Insight
When you see responsive buying at the VAL, expect a rotation back toward the POCDefinitionPoint of Control — the price with the highest volume. Where the most trading happened. — that is the market doing what it should. When you see initiative buying at the VAHDefinitionValue Area High — the upper boundary of the zone where 70% of volume traded. (breaking through it with conviction), that is the market doing something unexpected — new buyers are driving for higher value. Follow the initiative, fade the responsive.
Balance Area Breakout and Failed Auction
When value areas overlap across multiple sessions, a balance area (bracket) forms. Price rotates within this range, and the composite POCDefinitionPoint of Control — the price with the highest volume. Where the most trading happened. acts as a magnet. The real trading opportunities come when price attempts to leave the bracket.
The Breakout
When time and volume build at the edge of a balance area — not just a single probe, but actual acceptance — a genuine breakout is developing:
- Trade in the breakout direction once price establishes value outside the bracket (multiple TPODefinitionTime Price Opportunity — a letter printed at each price level per 30-minute period on a Market Profile chart. periods printing outside)
- Target a measured moveDefinitionA price projection where Leg B equals Leg A. Halsey's primary target is the -23.6% extension beyond 100%. equal to the height of the bracket, projected from the breakout point
- The bracket edge (the line that was resistance) becomes support on pullbacks
- Confirm with initiative activity — you want to see initiative buying above the bracket, not just responsive selling drying up
The Failed Auction
If price breaks beyond the balance area but fails to establish value in the new zone and re-enters the bracket, expect a full rotation to the opposite end of the balance. This is one of the highest-probability setups in Market ProfileDefinitionA chart format using TPO letters to show how long price traded at each level. Reveals the shape of the auction.:
- The failure means the breakout attracted no new participants — it was a false move
- Traders who entered on the breakout are now trapped and will liquidate, fueling the reversal
- Target the opposite side of the bracket (or the composite POCDefinitionPoint of Control — the price with the highest volume. Where the most trading happened. as a minimum)
- Confirmation: price re-enters the bracket for two or more consecutive 30-minute periods (same acceptance logic as the 80% Rule)
Key Insight
The failed auction at a bracket edge is the Market ProfileDefinitionA chart format using TPO letters to show how long price traded at each level.
