BB-Model Inspired Absolute Strength Index📊 BB-Model Inspired Absolute Strength Index (ASI) Author: © GabrielAmadeusLau Category: Momentum Oscillator / Adaptive Model / Divergence Tool 🔍 Overview The BB-Model Inspired ASI is an advanced oscillator that combines a novel BB-model weighted moving average with percentile-based return normalization to quantify absolute market strength. This hybrid design allows the indicator to adapt dynamically to volume, volatility, and price structure, while detecting divergences and extremes with high sensitivity. 🧠 Key Concepts 🧩 1. BB-Model Weighting Engine Each price in the lookback period is weighted by: Fitness: Either Volume or ATR. Decay: An exponential penalty applied to older data. This results in a context-aware moving average that prioritizes impactful recent bars while ignoring stale noise. 📈 2. Absolute Strength Index Calculation Computes returns from the BB-weighted price history. Sorts returns and identifies thresholds for: Top Percentile (Winners) – Strong upside moves. Bottom Percentile (Losers) – Strong downside moves. The current return is normalized within this dynamic range, scaled to , producing the ASI oscillator. 🧰 3. Signal Line & MA Smoothing Select from SMA, EMA, WMA, RMA, or HMA to smooth the ASI signal. Fully customizable length and styling. 🔄 4. Divergence Detection (Optional) Detects bullish and bearish divergences between ASI and price using pivot highs/lows. Highly customizable: Adjustable lookback window. Optional Heikin-Ashi integration. Color-coded plots and labels. Alerts for divergence events. ⚙️ Inputs Summary Parameter Description Fitness Source Volume or ATR Decay Factor Penalty on older bars Returns Lookback How many bars to calculate return distribution Percentile Thresholds Set overbought and oversold bands dynamically MA Type & Length Control signal smoothing Divergence Settings Toggle divergence logic and sensitivity 📌 Use Cases Detect when absolute directional strength is reaching exhaustion. Spot early signs of bullish or bearish divergences between momentum and price. Filter signals by volume or volatility importance using BB-model weighting. Use in combination with trend filters for precision entries/exits.

Absolute Strength Index [ASI] (Zeiierman)█ Overview The Absolute Strength Index (ASI) is a next-generation oscillator designed to measure the strength and direction of price movements by leveraging percentile-based normalization of historical returns. Developed by Zeiierman, this indicator offers a highly visual and intuitive approach to identifying market conditions, trend strength, and divergence opportunities. By dynamically scaling price returns into a bounded oscillator (-10 to +10), the ASI helps traders spot overbought/oversold conditions, trend reversals, and momentum changes with enhanced precision. It also incorporates advanced features like divergence detection and adaptive signal smoothing for versatile trading applications. █ How It Works The ASI's core calculation methodology revolves around analyzing historical price returns, classifying them into top and bottom percentiles, and normalizing the current price movement within this framework. Here's a breakdown of its key components: ⚪ Returns Lookback The ASI evaluates historical price returns over a user-defined period (Returns Lookback) to measure recent price behavior. This lookback window determines the sensitivity of the oscillator: Shorter Lookback: Higher responsiveness to recent price movements, suitable for scalping or high-volatility assets. Longer Lookback: Smoother oscillator behavior is ideal for identifying larger trends and avoiding false signals. ⚪ Percentile-Based Thresholds The ASI categorizes returns into two groups: Top Percentile (Winners): The upper X% of returns, representing the strongest upward price moves. Bottom Percentile (Losers): The lower X% of returns, capturing the sharpest downward movements. This percentile-based normalization ensures the ASI adapts to market conditions, filtering noise and emphasizing significant price changes. ⚪ Oscillator Normalization The ASI normalizes current returns relative to the top and bottom thresholds: Values range from -10 to +10, where: +10 represents extreme bullish strength (above the top percentile threshold). -10 indicates extreme bearish weakness (below the bottom percentile threshold). ⚪ Signal Line Smoothing A signal line is optionally applied to the ASI using a variety of moving averages: Options: SMA, EMA, WMA, RMA, or HMA. Effect: Smooths the ASI to filter out noise, with shorter lengths offering higher responsiveness and longer lengths providing stability. ⚪ Divergence Detection One of ASI's standout features is its ability to detect and highlight bullish and bearish divergences: Bullish Divergence: The ASI forms higher lows while the price forms lower lows, signaling potential upward reversals. Bearish Divergence: The ASI forms lower highs while the price forms higher highs, indicating potential downward reversals. █ Key Differences from RSI Dynamic Adaptability: ASI adjusts to market conditions through percentile-based scaling, while RSI uses static thresholds. █ How to Use ASI ⚪ Trend Identification Bullish Strength: ASI above zero suggests upward momentum, suitable for trend-following trades. Bearish Weakness: ASI below zero signals downward momentum, ideal for short trades or exits from long positions. ⚪ Overbought/Oversold Levels Overbought Zone: ASI in the +8 to +10 range indicates potential exhaustion of bullish momentum. Oversold Zone: ASI in the -8 to -10 range points to potential reversal opportunities. ⚪ Divergence Signals Look for bullish or bearish divergence labels to anticipate trend reversals before they occur. ⚪ Signal Line Crossovers A crossover between the ASI and its signal line (e.g., EMA or SMA) can indicate a shift in momentum: Bullish Crossover: ASI crosses above the signal line, signaling potential upside. Bearish Crossover: ASI crosses below the signal line, suggesting downside momentum. █ Settings Explained ⚪ Absolute Strength Index Returns Lookback: Sets the sensitivity of the oscillator. Shorter periods detect short-term changes, while longer periods focus on broader trends. Top/Bottom Percentiles: Adjust thresholds for defining winners and losers. Narrower percentiles increase sensitivity to outliers. Signal Line Type: Choose from SMA, EMA, WMA, RMA, or HMA for smoothing. Signal Line Length: Fine-tune the responsiveness of the signal line. ⚪ Divergence Divergence Lookback: Adjusts the period for detecting divergence. Use longer lookbacks to reduce noise. ----------------- Disclaimer The information contained in my Scripts/Indicators/Ideas/Algos/Systems does not constitute financial advice or a solicitation to buy or sell any securities of any type.

Accumulation Swing Index (ASI) The Accumulation Swing Index is a cumulative total of the Swing Index. The Accumulation Swing Index was developed by Welles Wilder. The SwingIndex function was developed to help cut through the maze of Open, High, Low and Close prices to indicate the real strength and direction of the market. The Swing Index function looks at the Open, High, Low and Close values for a two-bar period. The theory is that there are four cross-bar and one intra-bar comparisons that are strong indicators of an up or down day. The Swing Index returns a number between -100 and 100. If the factors point toward an up day, then the function value will be positive and vice versa. In this way, the Swing Index gives us definite short-term swing points, and it can be used to supplement other methods as a breakout indicator. A breakout is indicated when the value of the Accumulation Swing Index (ASI) exceeds the ASI value on the day when a previous significant High Swing Point was made. A downside breakout is indicated when the value of the ASI drops below the ASI value on a day when a previous significant low swing point was made. Since only futures have a relative daily limit value, this function only makes sense when applied to a futures contract. If you use this function and it only plots a zero flat line, check the Daily Limit value.
