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.
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.
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.
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.
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.
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.
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."
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 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.
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.
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.
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.
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.
Cycle Equity Curve (Illustrative)
Performance data is illustrative. Statistics update automatically as cycles complete. Commission simulation available in settings.
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.
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."
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.
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.
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.
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.
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.
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.
Cycle marker crosses the 0° boundary — Long entry fires on the next bar open.
Position held as the cycle advances through 90° and 180° harmonics.
Cycle reaches the configured exit degree — trade closes regardless of price action.
