Scale

MatrixScaleDownLibrary "MatrixScaleDown" Provides a function to scale down a matrix into a smaller square format were its values are averaged to mantain matrix topology. method scale_down(mat, size)   scale a matrix to a new smaller square size.   Namespace types: matrix   Parameters:      mat (matrix) : Source matrix.      size (int) : New matrix size.   Returns: New matrix with scaled down size. Source values will be averaged together.

Feature ScalingLibrary "Feature_Scaling" FS: This library helps you scale your data to certain ranges or standarize, normalize, unit scale or min-max scale your data in your prefered way. Mostly used for normalization purposes. minmaxscale(source, min, max, length)   minmaxscale: Min-max normalization scales your data to set minimum and maximum range   Parameters:      source      min      max      length   Returns: res: Data scaled to the set minimum and maximum range meanscale(source, length)   meanscale: Mean normalization of your data   Parameters:      source      length   Returns: res: Mean normalization result of the source standarize(source, length, biased)   standarize: Standarization of your data   Parameters:      source      length      biased   Returns: res: Standarized data unitlength(source, length)   unitlength: Scales your data into overall unit length   Parameters:      source      length   Returns: res: Your data scaled to the unit length

Normalized Oscillators Spider Chart [LuxAlgo]This indicator displays a spider chart overlaid on the user’s current chart allowing the visualization of information given by various normalized oscillators. It is possible to customize the spider chart by hiding certain oscillators from within the settings which removes their corresponding spokes from the chart. Users can control the length settings of each oscillator individually or use a global length setting that applies to every oscillator. An additional meter element is displayed and aims to give the overall sentiment returned by the oscillators. This can also be used to gauge whether the market is trending or ranging. This is a relatively simple application of a spider chart but can prove to be useful to some users. 1. Settings RSI: Displays the Relative Strength Index spoke on the spider chart, includes the length setting on the right of the toggle. %K: Displays the Stochastic Oscillator "%K" spoke on the spider chart, includes the length setting on the right of the toggle. COR: Displays the Correlation Oscillator spoke on the spider chart, includes the length setting on the right of the toggle. MFI: Displays the Money Flow Index oscillator spoke on the spider chart, includes the length setting on the right of the toggle. WPR: Displays the Williams Percent Rank oscillator spoke on the spider chart, includes the length setting on the right of the toggle. %UP: Displays the percentage of upward variations spoke on the spider chart, includes the length setting on the right of the toggle. CMO: Displays the Chande Momentum Oscillator spoke on the spider chart, includes the length setting on the right of the toggle. AOS: Displays the Aroon oscillator spoke on the spider chart, includes the length setting on the right of the toggle. Global Oscillators Length: Determines whether all oscillators should use the same length settings, determined by the setting on the right of the toggle. 1.1 Style Settings Spider Chart Length: Determines the horizontal width of the spider chart. Spider Chart Offset: Offset between the most recent bar and the left extremity of the spider chart. 2. Usage A spider chart can be a very useful visualization tool when it comes to seeing the individual characteristics of various variables at the same time. Here, the tool can give a general sentiment on the direction of the trend without adding each indicator to your chart. It is also possible to determine when an oscillator is considered overbought or oversold with this indicator. The dashed line represents the central value for each oscillator. Disabling any of the oscillators from the settings will return a spider chart using fewer spokes. The script also displays a meter that can be used to determine the overall sentiment given by all oscillators. This metric is based on the average value between each oscillator. An overall sentiment closer to 50 would indicate a ranging market.

Date-selected Synch and Compare Script Module [yoxxx]This Script is a Convenience Script Module for calculations based or started on a fix time / date. (In difference to bar_index-based where the reference point is shifting from bar to bar, thus is dynamic). Purpose examples: - Comparison by start date - Time driven studies or strategies - Measuring from Date of Interest The script also contains a date input box with the feature of auto-converting the default time to local user time (a newer feature of Tradingview which too me a lot of research to find; so here integrated). Last not least it the module gives you a ready to go example for multi security comparison on percentage scale with a free selectable start date. Enjoy Yoxxx P.S:. For further notes look at the script code. They are concerning usage and how avoiding some strange display issues.
