[blackcat] L5 Alchemy Gold (ALGOLD)

15 Jan 2024

"[blackcat] L5 Alchemy Gold (ALGOLD)" indicator is a trend-following indicator that blends volume and price data to create a MACD-like oscillator, aiming to address the lagging issue typical in price-only indicators. The integration of leading volume information with lagging price data is a smart approach to create more timely signals. Additionally, incorporating a volatility filter to reduce false signals during sideways markets is a thoughtful enhancement.

It is shaping up to be quite comprehensive. It includes:

• - An adaptive filter for smoothing price and volume data.
• - A volatility filter based on Average True Range (ATR).
• - A trigger moving average for generating smoothed price information.
• - An ALMA (Arnaud Legoux Moving Average) for further filtering of price and volume.
• - A divergence detector to identify potential trend reversals.

Entry Criteria: A composite crossover and crossunder of the fast and slow lines of the ALGOLD oscillator.
Exit Criteria: A crossover and crossunder of the fast and slow lines of the ALGOLD oscillator, but using a lower time frame for more sensitivity.

The input parameters of "[blackcat] L5 Alchemy Gold (ALGOLD)" indicator, are categorized into three groups:

Group 1, Alchemy Setting:

• Alchemy Sharpness (Default: 7) - Controls the sharpness of the adaptive filter.
• Alchemy Period (Default: 55) - Determines the smoothness of the oscillator.

Group 2, DVATAR Setting:

• DVATR Length (Default: 11) - Sets the period length for the DVATR, similar to ATR's Length.
• DVATR Threshold (Default: 0.07) - Adjusts sensitivity for sideways market detection.
• Smooth Length (Default: 21) - Smoothens the DVATR output, balancing with volatility detection.

Group 3, Divergence Setting:

• Parameters like Pivot Lookback, Max/Min of Lookback Range - Sets the sensitivity for divergence detection.
• Options to enable or disable plots for various types of divergence (Bullish, Hidden Bullish, Bearish, Hidden Bearish).

"[blackcat] L5 Alchemy Gold (ALGOLD)" indicator are vivid and intuitive:

Candle Bar Color:
Gradient color changes to indicate trend strength, with warmer colors for bullish and cooler colors for bearish trends.

Line Colors and Shapes:

• Green color represents the fast line, red for the slow line.
• Crosses of these lines signal entries (triangles) and exits (cross shapes).
• A band is created between these lines, filled with green for uptrends and red for downtrends.

Histogram:

• Red histogram for above 0 and uptrend.
• Blue histogram for above 0 and retracement.
• Green histogram for below 0 and downtrend.
• Yellow histogram for below 0 and bounce-up.

█ OVERVIEW

L5.2 Alchemy Gold (ALGOLD) is a comprehensive trend-following indicator that fuses multiple signal methodologies to generate high-quality entry and exit signals. It combines Kalman-filtered price analysis with Trend Strength Index (TSI) and Ehlers Predictive Average (EPA) techniques, featuring an integrated Trend Line system for visual confirmation and signal bot compatibility.

█ CONCEPTS

This indicator utilizes three core methodologies working in harmony:

Alchemy Gold Oscillator
• Kalman filter for noise reduction and price smoothing
• Volume-weighted price analysis for trend identification
• Gold/trigger line crossover system for trend direction

TSI-EPA Signal Engine
• Ehlers Predictive Average for momentum prediction
• Trend Strength Index for directional confirmation
• Transition detection for precise entry/exit timing

Signal Fusion Logic
• L6.6 TSI-EPA signals confirmed by L5 Gold trend
• Logical AND/OR modes for signal quality vs. quantity tradeoff
• Volume flow filter for additional confirmation

Trend Line System
• Fractal-based trend lines on gold oscillator
• Touch and break detection with visual labels
• Optional entry/exit signals on trend line breaks

█ HOW TO USE

Basic Setup
1 — Add the indicator to your chart
2 — Configure signal fusion mode (AND for quality, OR for quantity)
3 — Set anti-repaint mode based on your trading style
4 — Configure Signal Bot credentials if using automated alerts

Signal Interpretation
• EL (Entry Long): Bullish entry signal - L6.6 TSI-EPA transition confirmed by L5 gold uptrend
• ES (Entry Short): Bearish entry signal - L6.6 TSI-EPA transition confirmed by L5 gold downtrend
• XL (Exit Long): Close long position - TSI-EPA upper plot transitions to NA
• XS (Exit Short): Close short position - TSI-EPA lower plot transitions to NA
• TL-EL/TL-ES: Trend line break entry signals (when enabled)

Visual Elements
• Gold Line (Lime): Main oscillator showing price deviation from filtered value
• Trigger Line (Red): Signal line for gold oscillator crossovers
• Histogram[//b]: Momentum visualization with color-coded direction
• Background: Gray when volume flow condition is OFF
• Trend Lines: Red (resistance) and Lime (support) on oscillator
