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.

| 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 Target button, Value, the AI Analyzer and Siri. Portfolio is free. 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.
On iPhone, VIX, DJIA History and this guide are under More.
Tip: on iPhone, the ◀ ▶ arrows next to the symbol step through your watchlist, one symbol at a time. Open a holding from the Portfolio tab and they step through your portfolio instead.
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.
The Target button (Pro)
Tap Target at the top right of the chart to show where the price could be heading over the next year.
- Analyst target (dashed line): the analysts' average 12-month target, labeled with how far it is from the price and its Reach, the odds of the price touching it within a year. The line is green when Reach is 75 or more, gray from 50 to 74 and red below 50.
- OddsTrader range (shaded blue band): the prices with a 50% to 75% chance of being touched within a year, worked out from the symbol's own volatility and trend. ETFs, indexes, futures and coins get one too, even without analyst coverage. In a test on 23 markets since 1970, the 50% levels were touched 50% of the time and the 75% levels 72% of the time.
- Off the chart: when the range is above or below what the chart shows, its label carries a ▲ or ▼ instead.
- No analyst target? ETFs, indexes, futures, forex and coins have none, and tapping Target says so. The range still shows.
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 |

| 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.

- Price and targets: the price, its cash-flow value, the analysts' target and the OddsTrader range, all on one scale.
- Cash-flow value (DCF): a low, base and high value, with what if sliders for revenue growth, operating margin and the cost of capital. It also says how many times the base value the price is.
- Growth the price implies: the same model run backwards, giving the yearly growth today's price assumes, next to the growth of the last 3 years.
- Value creation and debt risk: return on capital against its cost, and how heavy the debt is.
- Banks and insurers: valued on book value and return on equity (an excess-return model), with the return on equity the price implies.
- Industry multiples: P/E, EV/EBITDA, EV/Sales and price to book against the industry's, and the price each one implies.
- Graham & Dodd and Buffett: Graham's number and checklist, and Buffett's owner earnings.
- Market gauges: the Shiller CAPE, the Buffett Indicator and the equity risk premium. In long tests these did say something about the market's next 10 years.
List: switch to List to value a whole watchlist. Sort it by Priced in (the growth the price implies), × base (price against the cash-flow value), ROIC or Reach. Colors show how much is priced in: bright green below 0×, pale green 0–1×, yellow 1–2×, orange 2–3×, red 3–4× and purple above 4× the base value. Tap a stock to value it.
For information only, not investment advice. A valuation is only as good as its assumptions.
Portfolio
Track what you own: tap +, enter the symbol, the quantity and your average cost.
- Columns: price, today's change, value, gain or loss and weight (fewer columns on iPhone).
- Several portfolios: keep Portfolio 1, 2 and more, and switch between them. They sync through iCloud.

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.
