[blackcat] L1 Swing Reversal Oscillator

2024年12月13日

█ OVERVIEW
The script defines a custom indicator called the "L1 Swing Reversal Oscillator," which integrates moving averages and RSI to detect possible swing reversals in market trends. Its core purpose is to produce signals derived from the oscillator's indications of overbought or oversold states.

█ LOGICAL FRAMEWORK

The script comprises multiple key segments:
1 — Custom Functions: Encompasses calculate_weighted_moving_average and calculate_l1_swing_reversal_oscillator.
2 — Input Parameters: Permits customization of moving average lengths and weights alongside RSI settings.
3 — Calculations: Employs predefined functions to determine oscillator readings.
4 — Plot Statements: Depicts oscillator outputs graphically on the chart.

Data processing follows this sequence: initial computation of the typical price, subsequent derivation of the adjusted CC1 metric, additional smoothing operations, and finally, RSI evaluation prior to plotting the resultant oscillator figures.

█ CUSTOM FUNCTIONS

• calculate_weighted_moving_average(source, length, weight): Generates a weighted moving average from the provided source material utilizing specified duration and coefficient inputs.
– Returns computed weighted moving average.

• calculate_l1_swing_reversal_oscillator(close_price, high_price, low_price, sma_length, sma_weight, rsi_length): Assesses the L1 Swing Reversal Oscillator leveraging closing, highest, and lowest prices along with defined SMA span, weighting factor, and RSI period.
– Yields an array featuring central CC1, CB1, CB2, and RSI metrics.

█ KEY POINTS AND TECHNIQUES

• Weighted Moving Average: Incorporates bespoke functionality for computing weighted moving averages, distinct from built-in Pine Script methods.
• RSI Calculation: Employs customized logic for calculating Relative Strength Index, offering adaptable computational approaches.
• Plotting Techniques: Implements color coding contingent upon oscillator values to emphasize visual cues regarding overbought and oversold statuses.
• Optimization: Furnishes adjustable parameters including SMA timeframe, weightage, and RSI interval enabling personalized fine-tuning per user requirements.

█ EXTENDED KNOWLEDGE AND APPLICATIONS

• Modifications: Potential enhancements involve integrating supplementary oscillators like MACD or Stochastic Oscillator alongside the existing L1 Swing Reversal Oscillator.
• Application Scenarios: Comparable methodologies can be adopted within various trading frameworks focusing on momentum shifts such as trend-following or mean reversion tactics.
• Related Concepts: Proficiency in crafting custom functions, manipulating moving averages, and interpreting RSI within Pine Script environment proves advantageous when altering or expanding on current script functionalities. Understanding utilization of nz and na functions for managing null data points adds significant depth.
