Fibonacci Path Profile [MantisAlgo] — Indicator by MantisAlgo — TradingView

The indicator combines the current A→B impulse, B→C retracement or extension, and live C→Now progress to continuously refine the historical sample.

🟢 ABC STRUCTURE
The indicator automatically detects alternating swing highs and swing lows and organizes them into an A-B-C structure.

Bullish ABC

A→B = upward impulse
B→C = downward retracement
The next D swing develops upward from C

Bearish ABC

A→B = downward impulse
B→C = upward retracement
The next D swing develops downward from C

A→B is used as the base swing for all subsequent Fibonacci measurements.

🟢 FIBONACCI MATCHING
The B→C movement is measured relative to the A→B impulse:
B→C Ratio = |B − C”https://www.tradingview.com/”A − B|

Historical cases are matched using:
Bullish or Bearish ABC direction
B→C Fibonacci range
Live C→Now progress

The B→C ranges are:
0–23.6%
23.6–38.2%
38.2–50%
50–61.8%
61.8–78.6%
78.6–100%
100–127.2%
127.2–161.8%
161.8%+

Up to 100% is classified as a Retrace, while values above 100% are classified as an Extension.
* To preserve a usable historical sample, all B→C values above 161.8% are grouped into a single 161.8%+ matching range rather than being divided into additional extension classes.

🟢 LIVE C→NOW MATCHING
The indicator also measures how far the active move has progressed from C relative to the B→C range.

C→Now = current progress from C relative to |B − C|

As price develops, this progress is used to filter historical cases that remained valid through a similar stage of the move.

🟢 D & E PATH
The profiles show the historical locations of the next two swing points:
D PathDistribution of the next swing point after C.
E PathDistribution of the following swing point after D.

Both D and E locations are normalized relative to the B→C range, allowing historical structures of different absolute sizes to be compared on the same basis.

The E Path is also separated into three structural outcomes:
🟥 B Break — E moves beyond the B level
🟨 No Break — E remains between B and C
🟦 C Break — E moves beyond the C level

The displayed percentages represent the weighted share of each outcome among the currently matched historical cases.

* For the D and E profiles, values beyond the displayed ±161.8% range are grouped into the outermost top or bottom bin rather than split into additional bins.

🟢 REAL-TIME PROFILE
The active profile is continuously recalculated as price develops.
This can update:
C→Now progress
matched historical cases
D Path distribution
E Path distribution
B Break / No Break / C Break probabilities

Because D and E represent the active forward path, both profile boxes are always displayed to the right of the current candle.

🟢 DYNAMIC C
Before a new D swing is confirmed, the B→C retracement may continue to a new extreme.
In that case, the active C point is updated:
Bullish ABC → C moves to a new lower low
Bearish ABC → C moves to a new higher high

This prevents an unfinished B→C leg from being treated as a completed swing.

🟢 WEIGHT
Two weighting methods are available:
Recent
More recent historical cases receive greater weight.
Weight = 1 / (1 + Age / 1500)
where Age is measured in bars.

Equal
Every matched historical case receives the same weight.
Use Recent to emphasize newer market behavior or Equal to view the unweighted historical distribution.

🟢 HOW TO USE
Use the indicator to evaluate how similar historical structures developed from the current setup.
D Path highlights where the next swing historically tended to form.
E Path shows how price developed after that D swing.
B Break / No Break / C Break summarizes the historical structural outcome.
C→Now continuously refines the sample as the active move progresses.
The profiles represent historical swing distributions, not traded volume.

They are designed to provide a probabilistic view of the active structure rather than a fixed Fibonacci price target.
