Original Time Cycles - W.D Gann

Introduction

A Modern Implementation of Classic Cycle Theory Original Time Cycles – W.D. Gann [AlgoFuego] is an advanced TradingView indicator inspired by the time‑cycle principles introduced by W.D. Gann, particularly as described in his classic work The Tunnel Thru the Air; Or, Looking Back from 1940. This tool brings Gann’s timeless insights on market rhythm and repeating time patterns into a systematic, data‑driven framework for today’s technical analysts and traders.

Bringing Gann’s Time Theory to Life

At its core, the indicator assumes that time is a primary market driver, and that trends tend to change when specific cycles complete—a central theme in Gann’s teachings: “When time is up, the trend changes.” By applying geometry, mathematics, and harmonic sequences to price history, the script identifies key time‑based reversal zones and projected market turning dates

How It Works

Unlike conventional technical indicators that focus primarily on price levels or momentum, Original Time Cycles emphasizes the X‑axis (time) aspect of market behavior:

  • Anchor Date & Cycle Length: Users choose a historical reference (anchor) date and define the overall cycle length, which serves as the foundation for all future cycle projections.

  • Full Cycle & Subdivisions: The indicator visualizes the full cycle and its harmonic subdivisions, helping traders spot potential turning points at major and minor intervals. 

  • Cycle Harmonics: By calculating rising and falling wave phases and harmonic degrees, the tool reveals deeper cyclical structures that might correspond to repeating market rhythms. 

Trade Signals & Execution Logic

Original Time Cycles can generate actionable entry and exit signals based on cycle behavior:

  • Angle Positions Mode: Signals trigger at predefined geometric degrees within the cycle, ideal for traders who use geometric cycle methods. 

  • Fractional Cycle Mode: Signals occur when fractional cycle waves change direction or after a specified duration, allowing flexible time‑based tactics. 

  • Modular Arithmetic: The script uses modular arithmetic to map time points into repeating intervals—similar to clock arithmetic—allowing cycle analysis to extend far into the past and future.

Backtesting & Performance Analytics

A built‑in trade engine enables realistic simulation and evaluation:

  • Risk Settings: Users can set stop‑loss and take‑profit levels to model risk management. 

  • Commission Simulation: Adds entry and exit cost modeling for realistic net results. 

  • Performance Table: Automatically summarizes key statistics such as win rate, total trades, returns, average performance, compound equity growth, and estimated next cycle date, providing a comprehensive view of historical performance. 

Chart Visualization & Alerts

The script enhances visual clarity with:

  • Cycle Waves & Harmonics: Clearly drawn cycle curves and background highlights showing major phase changes. 

  • Dynamic Candle Coloring: Candles automatically change color during active cycles or trades. 

  • Configurable Alerts: Users can enable alerts for entries, exits, stop‑loss triggers, and target hits.

Who It’s For

This tool is designed for traders and analysts who:

  • Believe that time cycles influence market behavior, not just price levels. 

  • Want to combine traditional technical analysis with structured, time‑based market timing

  • Seek a statistical framework to backtest and validate cycle hypotheses. 

A Cautionary Note

As with all cycle‑based indicators, historical cycle behavior does not guarantee future performance. Market conditions can also be shaped by fundamentals, macroeconomic events, or sentiment shifts—factors not accounted for in purely time‑based systems. Users should apply proper risk management and use cycle analysis as one part of a broader trading toolkit.
