rate_of_changeLibrary "rate_of_change"
// @description: Applies ROC algorithm to any pair of values.
// This library function is used to scale change of value (price, volume) to a percentage value, just as the ROC indicator would do. It is good practice to scale arbitrary ranges to set boundaries when you try to train statistical model.
rateOfChange(value, base, hardlimit)
This function is a helper to scale a value change to its percentage value.
Parameters:
value (float)
base (float)
hardlimit (int)
Returns: per: A float comprised between 0 and 100
Scaling
Price to Bar Ratio - Scale / Scales / ScalingPrice to Bar Ratio - Scaling
The Price to Bar Ratio - Scaling indicator for TradingView is designed for traders who utilize Gann-based techniques, Michael Jenkins methodologies, or geometric market analysis. It calculates the relationship between price movement and time (bars), providing a bar-to-price ratio that traders can use to align their charts with structured scaling methods.
Key Features:
• Geometry-Based Scaling – Designed for traders using market geometry, time/price balancing, or cycle analysis.
• Automatic Ratio Calculation – Computes a bar-to-price ratio based on price movement and time.
• Square & Rectangle Modes – Provides different scaling approaches to suit various analytical methods.
• Balanced Chart Structure – Helps maintain a proportional relationship between price and time.
• Customizable Inputs – Adjustable parameters for flexibility across different markets, assets, and timeframes.
How to Use:
1. Apply the Price to Bar Ratio - Scaling indicator to your TradingView chart.
2. Enable Magnet Mode in TradingView to help anchor points snap accurately to price levels.
3. Manually select your range using the four anchor points to define the area for calculation.
4. The indicator will generate a table displaying the calculated bar-to-price ratio.
5. Copy the recommended value from the table.
6. Open the chart settings in TradingView.
7. Locate the "Lock Price to Bar Ratio" input field.
8. Paste the copied ratio value into the input field and apply the changes.
9. Due to TradingView's limitations on the magnet option for anchor points, it is recommended to add a new instance of the indicator rather than dragging the anchor points to a new range. This prevents unwanted snapping behavior and ensures accurate recalculations.
Will be adding more formulas in the future.
Indicator in use:
Trig-Log Scaled Momentum OscillatorTaylor Series Approximations for Trigonometry:
1. The indicator starts by calculating sine and cosine values of the close price using Taylor Series approximations. These approximations use polynomial terms to estimate the values of these trigonometric functions.
Mathematical Component Formation:
2. The calculated sine and cosine values are then multiplied together. This gives us the primary mathematical component, termed as the 'trigComponent'.
Smoothing Process:
3. To ensure that our indicator is less susceptible to market noise and more reactive to genuine price movements, this 'trigComponent' undergoes a smoothing process using a simple moving average (SMA). The length of this SMA is defined by the user.
Logarithmic Transformation:
4. With our smoothed value, we apply a natural logarithm approximation. Again, this approximation is based on the Taylor expansion. This step ensures that all resultant values are positive and offers a different scale to interpret the smoothed component.
Dynamic Scaling:
5. To make our indicator more readable and comparable over different periods, the logarithmically transformed values are scaled between a range. This range is determined by the highest and lowest values of the transformed component over the user-defined 'lookback' period.
ROC (Rate of Change) Direction:
6. The direction of change in our scaled value is determined. This offers a quick insight into whether our mathematical component is increasing or decreasing compared to the previous value.
Visualization:
7. Finally, the indicator plots the dynamically scaled and smoothed mathematical component on the chart. The color of the plotted line depends on its direction (increasing or decreasing) and its boundary values.

Endpoint inputs allow to set an interval of interest for min-max scaler.
Can be (and should be) applied to other studies, or to the chart itself. In this example, I applied min-max scaling to weighted linear regression's slope values.
Unfortunately, "All data" is still "experimental" and works only on charts where less than 5000 bars are available. max_bars_back() didn't help.
Sup TV
Squeeze Momentum Indicator ModThis is a scaled version of LazyBear's Squeeze Momentum Indicator. Also added are fibo-based periods for BB and KC.
Forecast Oscillator (ps4)This is a scaled version of a Forecast Oscillator, which may be used as a standalone indicator or as a filter. Scaling allows to reduce data to a standard interval, say, 0..1 or -1..1. Oftentimes, it also makes data more contrastive.
Logistic Difference (ps4)This is an PS4 update to the Logistic Difference Indicator. It uses logistic function (sigmoid), which stabilizes the variance of data. The logistic function resembles the inverse Fisher transform. This version has a repaint/non-repaint switch and a scaling feature.
