What it is
The initial balance (IB) is the price range of the first hour of the regular session. Market-profile traders use it as the frame for the day: a narrow IB suggests the day will extend, a wide IB suggests the day is already mostly done. An IB extension is a move beyond the IB high or low that holds. This playbook trades the extension in the direction of the break, and, in a second mode, fades extensions that fail to hold.
It is the ORB's slower and more structured cousin. Because the range is a full hour, it captures more of the day's information and produces fewer, higher-quality signals.
The logic
The first hour is where the "other timeframe" participants (funds, hedgers, systematic desks) show whether they have inventory to move. If the IB is narrow and the market extends out of it, one side of the market has real business to do and short-term traders who traded the range must adjust. The extension holds because the responsible buying or selling continues, not because of a pattern.
On the other side of an extension are range traders fading the IB edges and the early breakout traders who got stopped on the first attempt. When the extension fails, the trapped breakout traders become the fuel for the fade. Both modes of the playbook are therefore about the same people, just on different days.
Setup rules
- Market: index futures and liquid commodity futures are the natural home; large caps also work. Use micro-futures to size properly.
- Timeframe: 30-minute profile bars to define structure, 5-minute chart for entries.
- IB definition: high and low of the first 60 minutes of regular trading hours.
- Extension mode conditions: IB height below 0.6 of the 20-day average IB; the break occurs between 10:30 and 12:30 ET; vwap is on the same side as the break; the profile is not already a "P" or "b" shape (a one-sided rally or selloff that has already happened).
- Failed extension conditions: price extends beyond the IB by less than 0.25 IB heights and closes back inside on a 30-minute bar, with the point-of-control still near the centre of the IB.
- Session filter: skip the setup on half-days and on the sessions around major holidays, when the initial balance forms on thin participation and extensions rarely hold; the same applies to the session immediately after a major fomc decision, where the profile is still digesting the event.
Entry, stop, target
Extension mode: enter on a 5-minute close beyond the IB after a retest of the IB edge holds. Stop is at the IB midpoint. Target 1 is the IB height projected from the break (a "one IB extension"), target 2 is two IB heights.
| Item | Level | Notes |
|---|---|---|
| IB high | 4,510.00 | IB height 20 points |
| IB low | 4,490.00 | |
| Entry | 4,511.25 | Close above IB high after retest |
| Stop | 4,500.00 | IB midpoint, risk 11.25 pts |
| Target 1 | 4,530.00 | One IB height, reward 18.75, about 1.7R |
| Target 2 | 4,550.00 | Two IB heights, about 3.4R |
Failed extension mode: enter on the 30-minute close back inside the IB, stop beyond the extension extreme, target the opposite IB edge. That trade is usually 1.5 to 2R and has a higher win-rate.
Position sizing and risk
Futures point values make sizing arithmetic unforgiving: with an 11.25 point stop on the E-mini, one contract risks over $560, which exceeds a 1 percent risk budget for most accounts. Use micro contracts to hit your risk number exactly, computed at /tools/position-size, and keep total open risk under the daily cap set in /learn/risk-management. One IB extension trade and one failed-extension trade per day is enough.
What breaks it
- Wide IB days. After a big overnight move the IB contains most of the day's range and there is nothing to extend into. The setup has no signal, and forcing one loses.
- Midday liquidity holes. Extensions that occur between 12:00 and 13:30 ET often stall because volume vanishes, then resume or reverse into the afternoon. Expect drawn-out trades.
- Regime shifts. During prolonged low-volatility periods the average IB is small and the "narrow IB" filter stops filtering. Recompute the reference average monthly.
- Costs. Modest relative to the stop, but rolling futures contracts and paying for market-profile data are real overhead.
How to test it
Chart the IB for at least 250 sessions and classify each day: extension up, extension down, failed extension, or no attempt. Compute the conditional statistics of your entry rules within each class. The interesting number is the distribution of the day's close relative to the IB, since that tells you how often extensions carry. You need 100 or more extension attempts to get a usable estimate of the expectancy; that may take a year of data in a quiet regime. Replay 30 sessions manually to make sure you can identify the profile shapes in real time, then simulate for 20 sessions.
Variations
- Half-IB extension that trades the 30-minute range on faster markets.
- IB plus volume profile: require the extension to leave a low-volume node behind it, which makes a return to the IB less likely.
- Overnight-range extension applied to the Globex session range instead of the IB.
