Fisher Transform Advanced
Fisher Transform Advanced ports the CCI Advanced context view onto a zero-centered Fisher Transform core. It is designed for clear turning-point and extreme reads, with trend context and conviction layers to make aggressive reversal behavior easier to judge.
Features
- Fisher core: normalized source range → recursive Fisher Transform → averaged main line → signal line
- Zero-centered scale: 0 midline with configurable ±1.5 default extreme levels; panel autoscales to the actual Fisher range instead of a fixed outer boundary
- Signals on raw Fisher values: crossover detection uses Fisher and its signal directly
- 4-state histogram: rising/falling × positive/negative drives four opacity states
- Gradient line:
color.from_gradient()from bull teal to bear pink based on Fisher extreme level - Shadow fills: gradient shadows between Fisher and zero
- Signal markers: configurable extreme-zone filter for Fisher/signal crosses; optional zero-cross dots
- Stall/absorption layer: flags bars where Fisher cools/heats sharply while price barely moves
- Trend context line: a slow Fisher Transform plotted faint behind the fast line; a cross against its side of zero is marked counter-trend
- Divergence wedge: fills the area between fast Fisher and the trend context only when they move in opposite directions
- Sentiment Bar: optional live label at the panel’s right edge — a signed ±100 score for how far Fisher sits inside its own OB/OS zone, plus a mini bar
- Signal Quality: optional 0-100 score next to each Bull/Bear Extreme marker — OB/OS-zone depth (50%) + context agreement (25%) + stall-free (25%)
- Alert conditions: bull/bear cross from extreme zone; zero-cross up/down
Scoring
The optional extreme filter requires the Fisher line to have visited the lower or upper extreme zone within the last N bars before a signal-line cross qualifies as a triangle signal.
Reversal Bias
Fisher Transform is intentionally reversal-heavy. It can make turns and extremes clearer than RSI-style oscillators, but it can also react aggressively in noisy markets. The stall and trend-context layers are visual conviction tools; they do not suppress the base cross.
Trend Context
The trend context line is a slower Fisher Transform. Above zero it supports long-side pullbacks; below zero it supports short-side bounces. Crosses against that side render as weak/faded triangles.
