User Guide

W. D. Gann pioneered the idea that price and time move in geometric harmony. Gann 9 brings his tools to your phone: Square of 9 price levels, range eighths, Gann angles, and calendar time windows, along with a two-line trend system that shows which way the market is leaning and how long the trend has lasted.

Getting started

Enter a symbol below the range buttons to draw its chart. Every other feature in the app builds on that symbol.

Tab	What you get
Chart	Price with its range eighths, channel, trendlines and color bars, plus the trend and swing lines underneath
AI	A one-page outlook card for the symbol, plus the full Market Pulse behind it
VIX	The S&P 500 against the VIX, with a green / red / yellow market signal
DJIA History	Every year of the Dow since 1886, with a decennial forecast
User Guide	This guide

Free or Pro? The chart, its lines and color bars, the Data view with Square of 9 levels, and your watchlists are free. Gann 9 Pro adds DJIA History, VIX trading, SAR and swing angles, options levels, the AI Analyzer, and Siri. Pro costs $5.99 per month or $59.99 per year; both plans begin with a free trial. If you previously purchased DJIA History or VIX, you keep access.

Tip: tap Data for the full Gann toolkit on one screen: Square of 9 levels, retracements and the next Gann dates.

The chart

The chart has two sections: price with Gann levels and angles above, and two yellow trend lines below. The color bars summarize both at a glance.

Pick your time frame

Button	Bars	Best for
1d	1-minute bars, today	Watching the session unfold
6M	Daily bars (the default)	Swings of days to weeks
1Y	Daily bars	The trend of the year
2Y	Weekly bars	Moves of weeks to months
5Y	Weekly bars	The big picture

Choosing 2Y or 5Y also switches your watchlist to weekly data. Pinch to zoom, drag with two fingers to pan, and double-tap to reset. On iPad, Line / Bar colors each bar green for a higher high and an up close, red for a lower low and a down close, or yellow otherwise.

Price, levels and angles

·        White line: the closing price. Touch the chart to display a crosshair.

·        Purple lines—the range eighths: Gann's 1/8 divisions of the six-month range. The bold, labeled line marks the halfway point, the most important level. Turn these lines off with 1/8 level lines in Settings.

·        Gray band—the channel: the typical range set at 80% of the largest moves above and below a pivot line.

·        Dashed green and red lines—Gann trendlines: a rising line from the period low and a falling line from the period high, drawn at the slope you choose under Angles = Trend.

·        SAR dots (Pro): a stop-and-reverse line that moves only when price crosses it. Green rises, red falls, and yellow is flat.

• Swing angles (Pro): green and red dots tracing the up and down swings.

·        Red, green, or yellow bar below price: green when the channel average and daily trend both point up, red when both point down, and yellow when they disagree.

·        T at the top: the number of bars the daily trend has continued. It turns yellow after 5, orange after 7, and red after 8—a reminder that extended runs may be due for a pause.

The two trend lines

The lower pane contains Gann 9's trend system: two yellow lines that step up or down with each bar.

• Solid yellow, the daily trend: steps up when the close beats the daily pivot line, down otherwise. It's the fast line.

·        Dotted yellow— the weekly trend: steps up when the close beats the weekly pivot line,. It is the slower line and reflects the larger swing.

·        Color bar at the top of the pane: green when both lines step up, red when both step down, and yellow when they disagree. This is the daily Buy, Sell, or Hold signal.

• Red and green ticks along the bottom: Gann cycle counts, in bars, from the period's low (red) and high (green). Pick a cycle set (A to D) in settings.

Options levels (Pro)

In Settings, choose Options: Off, OI, Gamma, or Both, and use the Expected move switch as needed. Dotted lines then show the largest call open interest (green), put open interest (orange), max pain (red), gamma wall (purple), put wall (pink), gamma flip (light blue), and expected move (gray).

The Data view

Tap Data to see Gann's full toolkit on one screen.

·        Trend and swing boxes: the current colors of both lines.

• Period low and high: with their dates.
• Square of 9 levels: prices one full turn of the square apart, counted up from the low, down from the high, and both ways from a price you choose.
• Retracements: 25%, 33%, 37.5%, 50%, 62.5%, 66%, 75% and 87.5% of the range.
• Eighth extensions: the low, high and your price stepped by eighths.
• Gann dates: the calendar days, from 11 to 365, counted from the low, the high and your date.
• Square: opens the Square of 9 wheel itself.

Watchlists

Your watchlists apply the two-line trend system to every symbol at once. Tap WL to open them; on iPad, they appear beside the chart. They sync across your devices through iCloud.

• B (green): the daily trend and swing line both step up.
• S (red): both step down.
• H, yellow: the swing line is up but the trend dipped, a pullback in an uptrend.
• H, orange: the swing line is down but the trend bounced, a retracement in a downtrend.
• T, shown as "3 | 7": how many bars the daily trend and the swing line have each run since they turned. Each number is green while its line rises, red while it falls.
• Daily or weekly: the list follows the chart. Pick 2Y or 5Y and the columns read B/S W and T W, on weekly bars.

Tip: Strong entries often appear when a yellow H turns back into a B with the trend count at 1. The pullback has ended, and both lines point up again.

Every signal at a glance

Keep this table handy. It lists every signal in Gann 9, where it appears, what triggers it, and how to use it.

Signal	Where	What triggers it	How to use it
Buy (B, green)	Watchlist, AI chips, lower-pane bar	Daily trend and swing line both step up	Trend and timing agree: the cleanest time to be long
Sell (S, red)	Watchlist, AI chips, lower-pane bar	Both step down	Stand aside or protect gains
Hold, yellow	Watchlist, AI chips	Swing line up, trend dipped	A pullback in an uptrend, often a chance to add
Hold, orange	Watchlist, AI chips	Swing line down, trend bounced	A retracement in a downtrend: don't chase it
T count	Watchlist, chart top	Bars since each line turned	1 to 3 is fresh; past 5 the chart's T turns yellow, past 8 red
Day or week one, reversal risk	AI swing bars	The line turned on the last bar	One-bar turns reverse often; wait for the second bar
Past the average, 1σ, 2σ, 3σ	AI swing bars	The swing outlasts its two-year average and spread	The longer it runs, the more mature; past 3σ is stretched
Getting overextended	AI Market Snapshot	A swing runs longer than its average	Tighten stops
Price bar green / red / yellow	Under the price	The channel's average and the daily trend agree or disagree	A second opinion on the trend
Bold range-eighth line	Chart	The halfway point of the 6-month range	Above it the range favours buyers; below it, sellers
Square of 9 levels	Data view, AI levels bar	Prices one turn of the square from the low, high or your price	Natural support and resistance
Gann trendlines	Chart (dashed)	Rising from the low, falling from the high	A break of the rising line warns the uptrend is tiring

Gann time windows	AI Timing tile, Data view	Gann day counts from the 6-month low and high	Dates when a turn is more likely, not certain
Cycle ticks	Lower pane	Gann cycle counts from the low (red) and high (green)	Clusters of ticks mark likely turning bars
Above / below the gamma flip	AI tile, chart	Price relative to the options gamma flip	Above: calmer moves. Below: expect bigger swings
Typical range	AI card	How far price usually moves in a week and a month	Size your stops and targets
Breadth gauges	AI card	Share of NYSE and NASDAQ stocks in uptrends	Below 35 the backdrop is weak; above 65 it's strong
VIX GREEN / RED / YELLOW	VIX tab	S&P 500 and VIX against their averages	GREEN favours stocks, RED warns, YELLOW is mixed

How the pieces fit: Gann looked for price and time to agree. A fresh Buy signal that appears near a Gann date and Square of 9 support is the kind of confluence he traded.

VIX and DJIA History

VIX: the market's mood in one color

The VIX tab compares the S&P 500 (SPY) with the VIX, Wall Street's fear gauge. Each has a yellow average line, and the signal compares both indexes with their averages.

Signal	When	What it means
GREEN	SPY above its average while the VIX is below its average	Stocks rising and fear falling: a healthy market
RED	SPY below its average while the VIX is above its average	Stocks falling and fear rising: be careful
YELLOW	Both above or both below their averages	Mixed: no clear message

• Lower strip: the signal on each bar.
• Upper strip: the last confirmed GREEN or RED, held through the yellow bars, so you see which regime you're in.
• On the AI tab: analyze right after viewing the VIX tab and the AI explains the pair.

DJIA History: has this year happened before?

The Dow has more than 140 years of history, and some years rhyme. DJIA History overlays selected past years on the target year so you can see which years it tracks most closely and how they finished.

• Target box: the year you're studying, drawn in white. It starts as this year.

·        Year boxes: up to 20 comparison years, each in its own color.

• Correlation row: how closely each year has tracked the target so far. 100% is a perfect match; negative means it moved the opposite way.
• Red Avg line: the average of the comparison years, a ready-made roadmap for the rest of the target year.
• Checkboxes: hide or show the years in groups of five.
• Correlation table: every year since 1886 ranked by how closely it matches.

The decennial forecast. Years ending in the same digit often behave similarly. Tap Decennial and enter a digit from 0 to 9. The chart loads every past year ending in that digit and displays their average in red as the forecast.

Choice	What it shows
All	Every year ending in the digit, the average and this year
Avg	Just the average, the cleanest forecast line
Bull	Only the years that finished up, and their average
Bear	Only the years that finished down, and their average
Year button	Shows or hides this year's line

Pick a digit that's still ahead, like 7 in 2026, and you get a forecast for 2027. Shortcut: type a single digit in the Target box. Try this: switch between Bull and Bear; whichever average the white line hugs is the kind of year the market is having.

Siri, sharing and your subscription

Ask Siri (Pro). Say "Analyze AAPL in Gann 9" or "Gann 9 analysis for SPY", and Siri reads the Market Snapshot aloud. Common names work too: Apple, the S&P, the Dow, Bitcoin or the VIX.

Compare two symbols. Type "AAPL vs MSFT" on the AI tab, or analyze right after the VIX tab, and Apple Intelligence writes a short news-style brief on the pair. It needs a device with Apple Intelligence.

Share a reading. Tap Share on the AI tab to send the outlook card as an image, with the symbol's cashtag in the caption.
