Initial Balance Breakout Strategy: Tested on 6 Years of NQ Futures

00The verdict in three lines

• We tested the initial balance breakout on NQ futures: mark the high and low of the first hour (9:30 to 10:30 New York), buy a break above or sell a break below until 13:30, with three common stop and target choices. One contract, $15.76 a round trip, 1,589 trades per version from 2020 to September 2026.
• The stop beyond the other side of the IB made money and beat chance: +$134,807 with a 1x IB extension target (+$85 a trade) and +$166,907 holding to the close (+$105 a trade), above the 95th percentile of the same trades on random days. The midpoint stop did not hold up.
• Not enough to pass. The edge is a few hundredths of an R per trade, the first-period t-statistic (1.66) is well short of the 2.5 we require and the validation profit factor is under 1.2. Buried, but the closest any NQ breakout has come on this site.

01What is the initial balance in trading?

The initial balance (IB) is the price range of the first hour of the regular session. The idea comes from Market Profile, developed by J. Peter Steidlmayer at the Chicago Board of Trade: in the first hour the early, mostly short-term traders set a range, and when price leaves it later in the day, larger players are taking one side. For US index futures such as NQ and ES the IB runs from 9:30 to 10:30 New York time.

• IB high and IB low: the highest and lowest prices of that hour. IB size: high minus low.
• Initial balance extension: a multiple of the IB size added beyond the high or subtracted below the low (0.5x, 1x, 2x). Traders use the 1x extension as a target: on a break above, IB high plus one IB size.
• The IB midpoint: halfway between high and low, used by some traders as a tighter stop.

On NQ the IB has grown with the index: its median was 92.3 points in 2020 and 216.5 points so far in 2026 (table in section 05).

02The initial balance breakout strategy we tested

• Entry: from 10:30, a buy stop one tick above the IB high and a sell stop one tick below the IB low. The first one touched is the trade, the other is cancelled. One trade a day; no entry after 13:30.
• IB-X1: stop one tick beyond the other side of the IB; target the 1x IB extension (about 1R).
• IB-MID: stop at the IB midpoint; the same 1x extension target (about 2R).
• IB-CLOSE: stop beyond the other side; no target.
• All three: a trade still open at the session close (16:00, or the exchange's early close) is closed there. Days with more than 3 minutes of the first hour missing, and early-close days ending before 12:30, are skipped.

Write-ups of the IB breakout differ on the stop and the target; these are the three we found most often. We fixed them, the hours and the costs on 21 October 2026, before computing a single initial balance, and tried nothing else afterwards.

03How we tested it

NQ (E-mini Nasdaq-100 futures), NinjaTrader 1-minute history, back-adjusted, January 2020 to 25 September 2026: 1,730 sessions with a usable initial balance. Exchange early closes from our futures calendar. Costs: $15.76 a round trip per contract (commission plus one tick of slippage on each fill), as in all our futures tests. Periods: 2020 to 2023, 2024 to March 2025, and a holdout from April 2025 already used by our earlier NQ tests. Opening range breakouts have been tried many times on this market (our 5-minute ORB test, the first 5-minute candle with a fair value gap, and unpublished ES versions), so the first-period bar is t ≥ 2.5. Control: every trade moved to another day at the same minute, same direction, same stop and target distances, 500 times. Engine check: hand-worked days (a gap through a level, the 13:30 cut-off, a stop and a target in the same minute, missing minutes, an early close) and an independent re-implementation that matched all 4,767 trades; it passed on its first run (ibb_selftest_result.txt).

Initial balance breakout win rate: how the trades ended

With the stop beyond the other side, the risk is the whole IB plus two ticks, a median of 127.5 points (+$2,550 on one contract), and more than half of the IB-X1 trades were still open at the close: neither the stop nor the 1x extension was reached. The win rate of 53.6% comes mostly from those afternoon closes. The midpoint stop halves the risk but was hit on 49.5% of trades.

05How often does NQ break the initial balance?

On the 1,730 sessions, the first level broken by 13:30 was the IB high on 49.7% of days and the IB low on 42.2%; on 8.2% price stayed inside the first-hour range until 13:30. No single minute ever reached both levels.

By initial balance size (descriptive, net per trade)

The size split was not part of the rules and we do not treat it as a filter: picking the best third after seeing it is exactly the kind of choice that makes a backtest look better than it is. It is here because IB traders ask about it.

06IB breakout or random entry?

The control places every trade on another day at the same minute, same direction and same stop and target distances, so it keeps the long-heavy mix and the rising market. The random versions earned about nothing on average, while IB-X1 and IB-CLOSE sat above the 95th percentile: the break of the initial balance picked better days than chance. It is the only gate that most of our breakout tests fail and this one passed.

07By period and side

Long trades: +$108,397 (859) and short trades: +$26,410 (730) for IB-X1; +$134,192 and +$32,715 for IB-CLOSE. 2022, a falling year for the Nasdaq, was the best year for all three, so the result is not only the bull market; but 2020 lost money for IB-X1 and IB-CLOSE, and the midpoint stop lost $41,857 in the most recent period.

08The gates

The data-gap check removed 2 trades from each version; no verdict changed. IB-X1 and IB-CLOSE failed on strength, not direction: positive in every period, above chance, but with a first-period t under 2.5 and a validation profit factor under 1.2. No proven edge means a convincing edge was not demonstrated, not that none exists; of everything we have tested on NQ, this was the result most worth watching. IB-MID is Fragile: positive overall, negative without its ten best trades.

Replication on ES (added 21 Oct 2026): we ran the same three rules, unchanged, on ES futures. They did not hold up there: -$1, +$11 and +$4 a trade, none above the 95th percentile of the control, one gate of six each (initial balance breakout on ES). The NQ result stands as computed, but it now has a second market that did not confirm it.

TWhat this shows, and what to take into your own tests

What the results show

• The two versions with the stop beyond the other side of the initial balance made money after costs over 6¾ years of NQ: +$85 a trade with a 1x extension target and +$105 holding to the close, on 1,589 trades each.
• They also beat the same trades placed on random days (the 97.2th and 95.4th percentile), which none of our earlier NQ opening range tests did. Something in the break of the first hour seems to carry information.
• But the edge is thin: about 0.037 R a trade in risk units, a first-period t of 1.66 against the 2.5 we require, and a validation profit factor of 1.12. A stop at the IB midpoint turned it into a loser in the most recent period.

What remains unknown

• Whether it lasts. The edge is small enough that ten years of NQ, or another market such as ES, could tell a different story; we tested one market.
• Filters that IB traders add (a trend filter, skipping very narrow or very wide balances, waiting for a retest). We fixed three common versions before the run and tried no others after seeing the result.
• Live fills. One tick of slippage per side is in the cost; a fast break through a level can cost more.

Why it was buried

Positive is not the same as proven. The profit per trade is small next to the trade-to-trade noise (the median risk is 127.5 points, +$2,550 a contract), so even 948 trades in the first period give a t of only 1.66; the validation period earned +$29,352 on a profit factor of 1.12, below our 1.2; and most of the money came from long trades in a market that rose. The midpoint stop version passed one gate of six.

What you can apply to your own tests

• Compare your breakout with the same trade on random days. Here it beat chance, which made the result worth taking seriously; most breakouts we have tested do not.
• Look at the average trade in risk units, not only dollars. Three or four hundredths of an R is easy to lose to slippage, a worse broker or one bad year.
• Decide the stop before you look. On the same entries, the stop at the other side of the IB and the stop at its midpoint gave opposite answers in the last eighteen months.

A note on the numbers: drawdown figures are measured on closed trades unless a table says it includes open losses. Open losses inside a trade are not counted in a closed-trade drawdown, so real account risk is higher, especially for systems with no stop. Backtests are not live trading.

FAQCommon questions

What is the initial balance in trading?

The price range of the first hour of the regular session, 9:30 to 10:30 New York time for US index futures. The idea comes from Market Profile (J. Peter Steidlmayer, Chicago Board of Trade): a later break of that range is read as one side taking control.

Does the initial balance breakout strategy work?

On NQ from 2020 to 2026 the version with the stop beyond the other side of the range made money after costs (+$134,807 on one contract with a 1x extension target) and beat random entries, but its first-period t-statistic was 1.66 against the 2.5 we require, so we could not call it a proven edge.

How often does NQ break the initial balance?

Almost every day: by 13:30 New York the first break was of the high on 49.7% of sessions and of the low on 42.2%; on 8.2% price stayed inside the first-hour range.

What is an initial balance extension?

A multiple of the initial balance size projected beyond its high or low. The 1x extension, a common target, is the IB high plus one IB size for a break up (the IB low minus one IB size for a break down).

Where should the stop go on an IB breakout?

In our test the stop one tick beyond the other side of the range did better than a stop at the midpoint: with the same entries and target, the midpoint stop won 42.7% of trades and lost $41,857 in the last eighteen months.

How was the strategy tested?

On NQ futures 1-minute data from 2020 to 2026, one contract, with rules written and dated before the data was run, costs included on every trade, results split into development, validation and holdout periods, a random-entry control as the benchmark, and every variant reported. Read the protocol.

10Data notes

Source. NinjaTrader NQ 1-minute history, back-adjusted continuous contract, on the New York clock; prices differ from a single contract month by the roll adjustments, not in the size of intraday moves. Fills: stop entries at the level, or at the minute's open if it opened beyond it; stops and targets the same way; inside a minute that reaches both, the stop is assumed first. One tick of slippage per fill is in the cost.
