Time Doesn't Lie. The Market
Moves on a Clock.

Original Time Cycles — W.D. Gann [AlgoFuego]

Gann's most closely guarded secret wasn't a price tool.
It was a calendar — encoded inside a novel, hidden in plain sight —
telling traders exactly when the market would change direction.

The Foundation

Gann Believed Time
Was the Cause.

Every indicator on your chart reacts to price. Gann did something different. He argued that price is the effect — and that time, governed by repeating mathematical cycles, is the cause. Not as philosophy. As a measurable, repeating law of nature that he spent decades encoding into precise forecasts.

"

When time is up, the trend changes. Mathematical science furnishes unmistakable proof of history repeating itself and shows that the cycle theory, or harmonic analysis, is the only thing that we can rely upon to ascertain the future.

W.D. Gann · The Tunnel Thru the Air, Page 77
1927
This principle — time governs price, not the reverse — is the entire foundation of this indicator. Every signal it generates is derived from cycle mathematics, anchored to a historical date, and projected forward using modular arithmetic. No price levels. No momentum. Just the clock Gann spent a lifetime calibrating.
II
The Secret

He Hid a Market Forecast
Inside a Novel.

In 1927, Gann published The Tunnel Thru the Air; Or, Looking Back from 1940 — a work most dismissed as fiction. It wasn't. It was a coded forecast. The dates, the cycle length, the mathematical key — all hidden in plain sight. We decoded it.

Four Clues.
One 1,940-Day Cycle.

Book Cover · Secret Key
"THRU" + "1940"
The title itself encodes the endpoint of the cycle — looking back from 1940 reveals the full arc.
Foreword · Starting Point
May 9, 1927
The foreword date is Gann's anchor — the origin from which all cycle projections flow.
Page 371 · The Principle
Days = Years = Degrees
Gann's mathematical equivalence: one day equals one year equals one degree of arc.
Page 405 · Cycle End
August 30, 1932
Gann's predicted end of the crisis period — exactly 1,940 days after the anchor date.
The result: a 1,940-day cycle that covered one of history's most dramatic market collapses — and validated Gann's forecasting methodology across a real historical sequence. The indicator ships with this exact cycle pre-configured as its default.
III
The Mechanism

An Anchor. A Length.
A Forward Projection.

The engine is deceptively elegant. One historically significant starting point. One cycle length in days. A modular arithmetic engine that wraps time like a clock — computing the exact phase of any date, however far from the anchor, without needing a single bar of chart history to exist.

1
Select an Anchor Date

Choose a historically significant event — a major market top, a war, a financial crisis — as the cycle's origin. Gann: "In order to know and predict the future, you only have to look up what has happened in the past and get a correct base." The default is May 9, 1927.

2
Define the Cycle Length

Set the number of days in one complete cycle — 360, 1,940, 2,920, or any value. Days, degrees, and years are interchangeable in Gann's framework. The modular arithmetic engine wraps any date into the correct cycle position, no matter how many centuries have passed.

3
Apply Harmonic Subdivisions

Divide the full cycle into halves (180°), thirds (120°), quarters (90°), fifths (72°), or custom fractions. Each subdivision reveals a minor turning point within the broader rhythm — Gann's "wheel within a wheel."

4
Signal Fires. Trade Executes.

When the cycle reaches a harmonic boundary — in either Angle Positions or Fractional Cycle mode — entry fires automatically. Stop-loss, take-profit, and the holding period manage the trade from open to close. The Next Turning Date projects the next completion window in advance.

The Signal

Cycle Completes.
Signal Fires.

The logic flows in one direction: time drives everything. When the cycle reaches its harmonic boundary, the engine responds — not after price confirms it, but precisely at the moment the mathematical clock marks the turn.

Two Modes. One Clock.

Angle Positions Mode gives you geometric precision — enter at a defined degree, exit at another. Fractional Cycle Mode operates automatically from wave phase reversals. Both derive from the same time cycle mathematics.

Geometric · Precision
Angle Positions Mode

Define a specific entry degree (e.g. 0°) and exit degree (e.g. 120°) within the cycle arc. Signals fire when the cycle reaches those exact geometric positions — the purist's implementation of Gann's harmonic degree logic.

Automatic · Wave-driven
Fractional Cycle Mode

Long signals fire when the wave phase shifts from falling to rising. Short when rising turns to falling. An optional bar-count exit closes the trade after a defined period — automatic rhythm-based signals without manual degree selection.

V
The Engine

Not Just a Signal.
A Complete Time System.

The cycle event triggers entry. Everything after — harmonic subdivisions, trade management, performance tracking, and the forward projection of the next turning date — runs automatically. You observe Gann's clock. The system executes.

Modular Arithmetic Engine

Maps any calendar date into a cycle position using clock-style arithmetic — regardless of how far the date lies from the anchor. Enables analysis of 60-year, 100-year, or 1,000-year macro cycles without requiring historical bars to exist on the chart.

Next Turning Date Forecast

Projects the exact forward date when the current cycle is expected to complete. Plan entries, exits, and stops in advance — calendar-based decision making that directly implements Gann's forecasting approach: "I will act on a specific date in the future."

Harmonic Subdivisions

Divide the cycle into halves, thirds, quarters, fifths, or custom fractions — each marking a minor turning point within the broader arc. Gann's "wheel within a wheel" visualised live on any chart, with configurable subdivision count from 2 to any depth.

Full Cycle Performance Statistics

Total cycles, win rate, min/max/average returns per cycle, compound equity before and after commission — all rendered on-chart as a live performance table. Updates automatically as each cycle completes.

Dynamic Candle Coloring

Candles color automatically by cycle phase — bullish during upward wave segments, bearish during downward segments, neutral in transition. Instantly reveals which bars were under active cycle influence.

Commission-Aware Backtesting

Simulate realistic trading costs with separate entry and exit commission percentages. All returns, win rates, and compound equity figures adjust automatically — preventing the inflated results that commission-blind systems produce.

Two Modes · One Clock

See the Difference
in Real Time.

Both modes read the same time cycle. What changes is how the signal fires. Toggle between them and watch how the same cycle produces two distinct entry strategies — geometric precision versus wave-rhythm automation.

Angle Positions Mode
Angle Positions Mode

Trade Between
Defined Degrees

You set an entry angle and an exit angle. When the cycle marker reaches the entry degree — the trade opens. When it reaches the exit degree — it closes. Exact. Geometric. Predictable.

Entry at 0°

Cycle marker crosses the 0° boundary — Long entry fires on the next bar open.

Holding Period

Position held as the cycle advances through 90° and 180° harmonics.

Exit at 270°

Cycle reaches the configured exit degree — trade closes regardless of price action.
