The first minutes of a session decide more than most traders give them credit for. Whoever controls the open — the early aggressor, the range they're willing to defend — sets the reference the rest of the session gets measured against. Watching that fight unfold as two nested boxes on the chart, instead of guessing it from candle color, is what Initial Balance and Open Range are for.

The one-minute glossary

• Open Range (OR): the High and Low built in the first stretch of a session — 15 minutes by default. It's the fast read: who showed up first and which way they leaned.
• Initial Balance (IB): the same idea over a longer window — 60 minutes by default. It's the slower, steadier read: where the session actually established fair price before the rest of the day tests it.
• Developing vs. locked: while the window is still open, the range is developing — it can still widen. Once the window closes, it locks and behaves as a firm level for the rest of the session.
• Extension: a projected target beyond the IB or OR High/Low, sized as a percentage of the range itself — used to set realistic breakout objectives instead of guessing how far a move can run.

Because OR and IB compute from the same session open at the same time, you get both reads simultaneously: the narrow window shows the first skirmish, the wide one shows who actually won it.

Three sessions, three timezones, one map

WyckFlow's Initial Balance / Open Range study doesn't stop at one session. It tracks Asia, London and New York independently, each resolved in its own timezone — by default that's your chart's own display timezone (Asia opening at 00:00, London at 09:00, New York at 15:30, all in chart time), but each session can be pointed at its real local zone instead, e.g. Asia set to Asia/Tokyo 09:00, with daylight-saving handled correctly per zone.

Running all three at once turns the chart into a handoff map rather than a single signal:

1. Asia typically builds a tighter, more contained range — often the accumulation the later sessions break out of.
2. London brings the first real volume of the day and frequently produces the first genuine directional push.
3. New York (15:30 chart time by default) usually carries the largest volume of the day and often sets the session's dominant direction.
4. The London/New York overlap is where fresh participants arrive together — a common spot for reversal days to form.

Reading the three side by side, rather than resetting your attention at every session boundary, is the whole point of drawing them simultaneously.

How to read it: acceptance, breakout, and the false-breakout fade

The core read is simple, and it's the same vocabulary the rest of the WyckFlow volume-profile toolkit uses:

• Acceptance: price holding above the IB High is a bullish edge; holding below the IB Low is a bearish edge. The range becomes the line in the sand for the rest of the session.
• Breakout with extension: a break of the IB High that keeps pushing toward the extension projection — a common default is 150–200% of the range — is a classic opening-range-breakout setup, and the projection gives you a target instead of an open-ended guess.
• False breakout: a break that pokes outside the range and then snaps back inside is a rejection, not a breakout — the fade target is the range's midline, not the far edge.
• No bars, no level: if a session has no data in its window (a weekend gap, a holiday), the study simply draws nothing for that occurrence rather than inventing a range from empty data.

Honest note: this is a pure level-drawing indicator — it has no entries, stop-loss or take-profit built in. It tells you where the boundaries are; the trade decision, sizing and risk are still yours. And the still-forming range is drawn dashed by default: it locks with no jump once the window closes, but until then, treat it as provisional, not a finished level.

Key settings worth knowing

Enable it via Study menu → WyckFlow → WyckFlow Initial Balance / Open Range — it's an overlay, so it drops straight onto the price chart, no separate pane to size.

The study ships with sensible defaults, but a few settings are worth understanding before you rely on it intraday:

• Sessions tab — Asia, London and New York each get their own enable toggle, timezone (chart timezone by default, or a real IANA zone), and Open/End time. All three are on by default.
• Open Range tab / Initial Balance tab — each has its own global window length (15 minutes for OR, 60 minutes for IB) plus a per-session override, so New York can run a different window than Asia if you want.
• Extension — off by default; turn it on and set the percentage of range to project once you want breakout targets, not just the raw box.
• Fill and midline — both optional, both off by default; the midline is the natural fade target for a false breakout.
• "Hide on Daily+ timeframe" — on by default, since IB/OR only makes sense intraday.
• "Draw at most N recent sessions" — caps how many past occurrences stay on the chart (10 by default) so the chart doesn't fill up with old boxes.

One mechanical limit is worth remembering: the window can't be finer than your chart's own timeframe. A 15-minute Open Range on a 30-minute chart collapses to the first candle's High/Low — drop to a lower timeframe or lengthen the window if that happens.

Suggested presets

For breakout trading specifically, pairing any of these with the extension turned on at 150–200% gives you a target instead of an open-ended breakout.

Summary

• Open Range = first 15 minutes by default; Initial Balance = first 60 minutes by default — both computed from the same session open.
• Runs on Asia, London and New York simultaneously, each in its own timezone.
• Acceptance above/below the range is the directional read; a poke-and-return is a false breakout, faded back toward the midline.
• The optional extension projection turns a breakout into a measurable target instead of a guess.
• The window can't be finer than your chart's timeframe, and a session with no bars simply draws nothing.

Frequently asked questions

What is the difference between Initial Balance and Open Range?

They're the same idea over two different windows measured from the same session open. Open Range is the fast read (15 minutes by default); Initial Balance is the slower, more established read (60 minutes by default). Both are drawn at once so you see the early skirmish and the settled range together.

How do I read a false breakout of the Initial Balance?

If price pokes above the IB High and then closes back inside the range, treat it as a rejection rather than a breakout — the natural fade target is the range's midline, not the far side. A genuine breakout instead keeps pushing toward the extension projection without snapping back in.

Which session's Initial Balance matters most?

All three carry information, but New York typically carries the most volume and most often sets the session's dominant direction, while Asia tends to build the tighter, more contained range that London or New York later break out of. Reading them together, rather than in isolation, is the point of running all three.

Can I use Initial Balance and Open Range outside US futures?

Yes — each of the three sessions can be pointed at its own real timezone (for example Asia set to Tokyo time) instead of the chart's default, so the study works for FX, crypto or any 24-hour instrument, not just RTH futures.

Is the WyckFlow Initial Balance / Open Range study free?

Yes. It ships in the free part of the WyckFlow bundle, works in MotiveWave's Community Edition, and doesn't require a license key to run.

The WyckFlow Initial Balance / Open Range study is a free part of the WyckFlow bundle at wyckflow.com/shop.html — it draws both ranges for all three sessions at once, with optional midline, fill and extension projection.
