Mystic's SPX Market Structure FibonacciThe script allows traders to define a low-anchor date and a high-anchor date, then automatically plots Fibonacci retracement and extension levels from that selected impulse range. It is designed to help traders study where price has previously paused, reversed, reclaimed, or accelerated around major structural levels.
This is not a signal generator. It does not predict tops or bottoms. It is a visual framework for studying market structure, pullback depth, extension behavior, and potential reaction zones.
What it plots
The indicator includes:
Retracement levels: 23.6%, 38.2%, 50%, 61.8%, 75%, 78.6%, and 100%
Upper extension levels: +23.6%, +38.2%, +50%, +61.8%, +75%, +78.6%, +100%, +127.2%, +150%, and +161.8%
Higher extension levels: +200%, +261.8%, +300%, +361.8%, and +423.6%
A shaded 61.8% to 75% retracement zone
Right-side labels for level identification
Adjustable anchor dates, label size, line width, colors, and visibility settings
How to use it
Choose a meaningful swing low and swing high, then use the plotted structure as a reference map.
Retracement levels can help identify where a pullback may become important. Extension levels can help identify where price may pause, consolidate, reject, or accelerate after breaking above the prior swing high.
The main purpose is to compare current price behavior against prior cycle behavior. For example:
A shallow retracement may suggest strong trend persistence
A reclaim of a prior extension may suggest repaired structure
A backtest of a breakout level may offer cleaner context than chasing an extended move
A fast move through multiple extension levels may suggest momentum, short-covering, or performance-chasing
A failure back below a reclaimed level may suggest a change in character
These levels should be treated as reference areas, not automatic trade entries.
Market structure read
This tool was built to study how the S&P 500 has behaved around fixed-anchor Fibonacci levels across recent market cycles.
A useful observation from this framework is that several major pauses, retracements, and reclaims have occurred near projected Fibonacci structure. That does not mean the levels are predictive by themselves. The value is in watching how price behaves when it reaches them.
In the current framework, the market has reclaimed several prior extension levels and moved into higher extension territory. That confirms strength, but it also means the move is no longer early. The indicator helps separate two different questions:
Is the trend still structurally intact?
Is the current location still attractive for new risk?
A strong trend can still be a poor entry if price is extended far above the prior base. This script is meant to make that distinction easier to study.
Open-source note
This script is published open-source so users can inspect the anchoring logic, level calculations, and drawing behavior directly.
There is no hidden signal engine, proprietary prediction model, or undisclosed performance logic. The goal is transparency. Traders can review the code, modify the anchor dates, adjust the visual settings, and adapt the script to their own charting workflow.
Limitations
Fibonacci levels are not guarantees. Price may reverse at a level, ignore it, consolidate around it, or move through it without reaction.
This indicator does not provide buy or sell signals. It does not include backtested performance results. It should be used with broader market structure, price action, volume, volatility, breadth, trend context, and risk management.
