Miha Kralj 3dd05f23e4 Refactor indicators to include "Ehlers" in names and descriptions for clarity
- Updated the name and description of the Hilbert Trendline (HTIT) to "Ehlers Hilbert Transform Instantaneous Trend (HTIT)".
- Changed the name and description of the MESA Adaptive Moving Average (MAMA) to "Ehlers MESA Adaptive Moving Average".
- Modified the Center of Gravity (CG) indicator to "Ehlers Center of Gravity (CG)".
- Renamed the Detrended Synthetic Price (DSP) to "Ehlers Detrended Synthetic Price (DSP)".
- Updated the Autocorrelation Periodogram (EACP) to "Ehlers Autocorrelation Periodogram (EACP)".
- Changed the Homodyne Discriminator (HOMOD) to "Ehlers Homodyne Discriminator (HOMOD)".
- Updated the Hilbert Transform Dominant Cycle Period and Phase indicators to include "Ehlers" in their names.
- Renamed the Hilbert Transform Phasor Components to "Ehlers Hilbert Transform Phasor Components (HT_PHASOR)".
- Updated the SineWave indicator to "Ehlers Hilbert Transform SineWave (HT_SINE)".
- Changed the Phasor Analysis indicator to "Ehlers Hilbert Transform Phasor Components (HT_PHASOR)".
- Updated the SSF-Based Detrended Synthetic Price to "Ehlers SSF Detrended Synthetic Price (SSFDSP)".
- Renamed the Ultimate Channel to "Ehlers Ultimate Channel (UCHANNEL)".
- Added new indicators: Moving Average Variable Period (MAVP), Ehlers Predictive Moving Average (PMA), Ehlers Reverse EMA (REVERSEEMA), and Ehlers Trendflex Indicator (TRENDFLEX).
- Updated various SVG badges to reflect changes in classes, comments, source files, lines of code, methods, and public types.

Oscillators

"Oscillators tell you when to act, not which direction to trade." Unknown

Oscillators fluctuate above and below a centerline or within bounded ranges. Useful for identifying overbought/oversold conditions, momentum shifts, and divergences. Best in ranging markets; trend-following indicators work better in trending markets.

Indicator Full Name Description
AC Acceleration Oscillator Second derivative of AO. Measures acceleration of market driving force.
AO Awesome Oscillator 5-period SMA minus 34-period SMA of bar midpoint. Bill Williams creation.
APO Absolute Price Oscillator Raw currency difference between fast and slow EMAs. Unbounded.
BBB Bollinger %B Position within Bollinger Bands. 0=lower band, 1=upper band.
BBS Bollinger Band Squeeze BB width < KC width indicates consolidation. Breakout imminent.
CFO Chande Forecast Oscillator Percentage difference between price and linear regression forecast.
DECO Ehlers Decycler Oscillator Dual HP bandpass isolating intermediate-frequency market cycles.
DPO Detrended Price Oscillator Removes trend via displaced SMA. Reveals cycles.
FISHER Ehlers Fisher Transform Converts prices to Gaussian distribution. Sharp reversals.
INERTIA Inertia Linear regression residual. Raw deviation from trend forecast.
KDJ KDJ Indicator Enhanced Stochastic. J = 3K - 2D provides leading signal.
PGO Pretty Good Oscillator Distance from SMA normalized by ATR. Units: ATR multiples.
SMI Stochastic Momentum Index Distance from range midpoint. More sensitive than classic Stochastic.
STOCH Stochastic Oscillator Close position within N-period high-low range. Classic overbought/oversold.
STOCHF Stochastic Fast Unsmoothed Stochastic. Faster but noisier.
STOCHRSI Stochastic RSI Stochastic applied to RSI. More sensitive than either alone.
TRIX Triple Exponential Average ROC of triple EMA. Filters noise through three smoothings.
TTM_WAVE TTM Wave Fibonacci-period MACD composite (Waves A/B/C). John Carter.
ULTOSC Ultimate Oscillator Multi-timeframe oscillator. Combines 7, 14, 28 period buying pressure.
WILLR Williams %R Inverse Stochastic. -100 to 0 range. Overbought/oversold.
