Original Time Cycles
W.D. Gann [AlgoFuego]

Select a historically significant event as the cycle's origin — a major market top or bottom, a war, a financial crisis, or an astronomical event. Gann wrote: "In order to know and predict the future of anything you only have to look up what has happened in the past and get a correct base or starting point." The more significant the anchor, the more accurate your future projections. The default anchor is May 9, 1927 — the date from Gann's own documented cycle.

Set the number of days in one complete cycle (e.g., 360, 1940, or 2920 days). Gann used natural mathematical divisions where days, degrees, and years are interchangeable units. Try different lengths — starting with 360 (one degree per day) or 1940 (Gann's encoded cycle) — and observe which resonates most with your market's historical turning points.

Once active, the indicator draws the full cycle arc as a sinusoidal wave overlay on your chart. Rising phases represent the market's expansive vibration; falling phases represent contraction. Watch how historical price action tends to reverse as each wave completes — this visual alignment between cycle structure and price history is the foundation of Gann's Law of Vibration.

Cycle completion dates are your primary reversal zones. When the cycle reaches its end, the probability of trend change increases significantly — this is the operational meaning of "When time is up, the trend changes." Mark these dates in advance and treat them as high-probability windows for entries, exits, or position re-evaluation rather than as guaranteed reversal signals.

Divide the full cycle into halves (180°), thirds (120°), quarters (90°), fifths (72°), or custom fractions to reveal minor turning points and continuation phases within the broader rhythm. Gann described this as "wheel within a wheel" — cycles within cycles. Subdivisions at 90° intervals (the default) align with Gann's foundational harmonic degrees and typically yield the highest concentration of meaningful market reactions.

Choose Angle Positions Mode to trade between predefined geometric degree ranges (e.g., enter at 0° and exit at 120°) — ideal for Gann purists seeking precise harmonic motion. Or choose Fractional Cycle Mode, which generates Long and Short signals automatically when the wave phase shifts from rising to falling or vice versa — suited for traders who prefer wave-driven, rhythm-based signals without manual degree selection.

Use the built-in statistics panel to evaluate historical cycle performance: win rate, return per cycle, min/max returns, and compound equity growth across all completed cycles. Enable commission simulation to reflect real trading costs. Confirm that your chosen anchor date and cycle length produce statistically consistent results before committing capital to live signals.

The Next Turning Date feature projects the forward date when the current cycle is expected to complete — providing a specific future window to plan entries, exits, and stop placement in advance. This transforms Gann's forecasting philosophy into an actionable, calendar-based decision-making system: "I will buy or sell the market on a specific date in the future with a specific stop loss and target, and I will exit on a specific date."

Keep a detailed trading journal recording your anchor points, cycle lengths, subdivision settings, and outcomes for each market you analyze. Over time, patterns will emerge showing which harmonics resonate most strongly with specific assets and timeframes. When a cycle produced a strong market reaction historically, expect a similar response when that same vibration recurs — this is the practical application of Gann's Law of Vibration: "Like causes produce like effects."
