Arrays

getSeries█   OVERVIEW This library is a Pine programmer’s tool containing functions that build an array of values meeting specific conditions. Its functions use concepts from our ConditionalAverages library , but instead of returning a single value, they return an array containing all the values meeting the conditions, which can then be processed as needed. This provides more flexibility to the programmer than a single value. The "getSeries" name of the library stems from the fact that is uses arrays to build the equivalent of custom series which can then be operated on using array-specific functions in the `array.*` namespace, looped through using a for...in structure to implement custom logic, or sent to functions designed to process arrays such as those in these libraries: ArrayStatistics , ArrayOperations , arrayutils or Averages . The eight examples illustrated in the library's code showcase the diversity of scenarios where the functions can be used. Look first. Then leap. █   FUNCTIONS The library contains the following functions: whenSince(​src, whenCond, sinceCond, length)   Creates an array containing the `length` last `src` values where `whenCond` is true, since the last occurence of `sinceCond`.   Parameters:      src : (series int/float) The source of the values to be included.      whenCond : (series bool) The condition determining which values are included. Optional. The default is `true`.      sinceCond : (series bool) The condition determining when the accumulated series resets. Optional. The default is false, which will not reset.      length : (simple int) The number of last values to return. Optional. The default is all values.   Returns: (float ) The array ID of the accumulated `src` values. rollOnTimeWhen(​src, timeWindow, cond, minBars)   Creates an array of `src` values where `cond` is true, over a moving window of length `timeWindow` milliseconds.   Parameters:      src : (series int/float) The source of the values to be included.      timeWindow : (simple int) The time duration in milliseconds defining the size of the moving window.      cond : (series bool) The condition determining which values are included. Optional. The default is `true`.      minBars : (simple int) The minimum number of values to maintain in the moving window. Optional. The default is 1.   Returns: (float ) The array ID of the accumulated `src` values. Note that the functions must be called on each bar to work correctly. They must thus be pre-evaluated before using their results in conditional branches.

Object: object oriented programming made possible! Hash map's in Pinescript?? Absolutely This Library is the first step towards bringing a much needed data structure to the Pine Script community. "Object" allows Pine coders to finally create objects full or unique key:value pairs, which are converted to strings and stored in an array. Data can be stored and accessed using dedicated get and set methods. The workflow is simple, but has a few nuances: 0. Import this library into your project; you can give it whatever alias you'd like (I'll be using obj) 1. Create your first object using the obj.new() method and assign it a variable or "ID". 2. Use the object's ID as the first argument into the obj.set() method, for the key and value there's one extra step required. They must be added as arguments to the appropriate prop_() method. Note: While objects in this library technically only store data as strings, any primitive data type can be converted to a string before being stored, meaning that one object can hold data from multiple types at once. There's a trade off though..Pine Script requires that all exported function parameters have pre-defined types, meaning that as convenient as it would be to have a single method for storing and returning data of every type, it's not currently possible. Instead there are functions to add properties for each individual type, which are then converted to strings automatically (the original type is flagged and stored along with the data). Furthermore, since switch/if statements can only return values of the same type, there must also be "get" methods which correspond with each type. Again, a single "get" method which auto-detects the returned value's type was the goal but it's just not currently possible. Instead each get method is only allowed to return a value of its own type. No worries though, all the "get" methods will throw errors if they can't access the data you're trying to access. In that error message, you'll be informed exactly which "get" method you need to use if you ever lose track of what type of data you should be returning. 3. The second argument for obj.set() method is the obj.prop_() method. You just plug in your key as a string and your value and you're done. Easy as that. Please do not skip this step, properties must be formatted correctly for data to be stored and accessed correctly 4. Obj.get_ (s: string, f: float, b: bool, i: int) methods are even easier, just choose whichever method will return the data type you need, then plug in your ID, and key and that's it. Objects will output data of the same type they were stored as! There's a short example at the end of the script if you'd like to see more! prop_string(string: key, string: value) returns property formatted to string and flagged as string type prop_float(string: key, float: value) returns property formatted to string and flagged as float type prop_bool(string: key, bool: value) returns property formatted to string and flagged as bool type prop_int(string: key, int: value) returns property formatted to string and flagged as int type Support for lines and shapes coming soon! new() returns an empty object set(string : ID, string: property) adds new property to object get_f(string : ID, string: key) returns float values get_s(string : ID, string: key) returns string values get_b(string : ID, string: key) returns boolean values get_i(string : ID, string: key) returns int values More methods like Obj.remove(), Obj.size(), Obj.fromString, Obj.fromArray, Obj.toJSON, Obj.keys, & Obj.values coming very soon!!

[LIB] Array / Matrix DisplayLibrary "ArrayMatrixHUD" Show Array or Matrix Elements In Table For Arrays: Set the number of rows you want the data displayed in and it will generate a table, calculating the columns based on the size of the array being displayed. For Matrix: It will automatically match the Rows and Columns to the values in the matrix. Note: On the left, the table shows the index of the array/matrix value starting at 1. So, to call that value from inside the array, subtract 1 from the index value to the left. For matrices, keep in mind that the row and column are also starting at one when trying to call a value from the matrix. The numbering of the values on the left is for display purposes only. viewArray(_arrayName, _pos, _txtSize, _tRows)   Array Element Display (Supports float, int, string, and bool)   Parameters:      _arrayName : ID of Array to be Displayed      _pos : Position for Table      _txtSize : Size of Table Cell Text      _tRows : Number of Rows to Display Data In (columns will be calculated accordingly)   Returns: A Display of Array Values in a Table viewMatrix(_matrixName, _pos, _txtSize)   Matrix Element Display (Supports float, int, string, and bool)   Parameters:      _matrixName : ID of Matrix to be Displayed      _pos : Position for Table      _txtSize : Size of Table Cell Text   Returns: A Display of Matrix Values in a Table

PivotThis library was designed to create three different datasets using Bill Williams fractals. The goal is to spot trends in reversal data and ultimately use these datasets to help predict future price reversals. First, the pivot() function is used to initialize and populate three separate arrays (high pivot , low pivot , all pivots ). Since each high/low price depends on the bar_index, the bar_index, pivot direction(high/low), and high/low values are compressed into a string to maintain the data's integrity ("__"). Once each string array is populated and organized by bar_index, all three are returned inside a tuple. The return value must be deconstructed H,L,A =pivot() for each array's values to be accessed using getPivot() . This boilerplate allows for data to be accessed more efficiently in a recursive environment. getPivot() was designed to be used inside of a for or while block to populate matrices for further analyses. Again, getPivot() return values must be exposed through deconstruction. x,d,y =getPivot(). See code for more details. pivot(int XLR) initializes and populates arrays Parameters XLR - number of bars to the left and right that must be lower for a high to be considered a pivotHigh, or vice versa. This number will drastically change the size and scope of the returned datasets. smaller values will produce much larger datasets, which might model short term price activity well. In contrast, larger values will produce smaller datasets which might model longer term price activity well. Returns - tuple [string ] getPivot(string arrayID, int index) accesses array data Parameters arrayID - the variable name for one of the three arrays returned by pivot(). index - the index of the provided array, with 0 being the most recent pivot point. can be set to " i " in a loop to access values recursively Returns - tuple

FunctionPolynomialFitLibrary "FunctionPolynomialFit" Performs Polynomial Regression fit to data. In statistics, polynomial regression is a form of regression analysis in which the relationship between the independent variable x and the dependent variable y is modelled as an nth degree polynomial in x. reference: en.wikipedia.org www.bragitoff.com gauss_elimination(A, m, n) Perform Gauss-Elimination and returns the Upper triangular matrix and solution of equations.   Parameters:      A : float matrix, data samples.      m : int, defval=na, number of rows.      n : int, defval=na, number of columns.   Returns: float array with coefficients. polyfit(X, Y, degree) Fits a polynomial of a degree to (x, y) points.   Parameters:      X : float array, data sample x point.      Y : float array, data sample y point.      degree : int, defval=2, degree of the polynomial.   Returns: float array with coefficients. note: p(x) = p * x**deg + ... + p interpolate(coeffs, x) interpolate the y position at the provided x.   Parameters:      coeffs : float array, coefficients of the polynomial.      x : float, position x to estimate y.   Returns: float.

InitialiseArraysLibrary "InitialiseArrays" @description: Efficiently create arrays, populating them with an arbitrary number of elements and setting their starting values. Works with a mix of typed and na values. A limitation of the built-in functions to create arrays is that while you can create and populate arrays with a single command, you can only set all elements to the same value in this way. Or, you can create an array from a set of values or variables, but you can't include any na values. Now, it's easy enough to work around this, but I wanted to make something more efficient (because I want to use lots of arrays), hence this library. Calling a function from here is more efficient because you only do it once (assuming it's a var) and don't evaluate an if condition each run, and don't create unnecessary variables. It's also easier to read and takes less space. f_initialiseBoolArray() @function f_initialiseBoolArray(string _values) Creates a boolean array, populated with the values that you specify in the input string. @param _values is a string that contains a comma-separated list of the values that you want to initialise the boolean array with. Values other than true, false, and na are disregarded. Spaces are disregarded. @returns Returns a boolean array of arbitrary length. f_initialiseFloatArray() @function f_initialiseFloatArray(string _values) Creates a float array, populated with the values that you specify in the input string. @param _values is a string that contains a comma-separated list of the values that you want to initialise the float array with. Non-numerical entries are converted to NaN values. Spaces are disregarded. @returns Returns a float array of arbitrary length. f_initialiseIntArray() @function f_initialiseIntArray(string _values) Creates an int array, populated with the values that you specify in the input string. @param _values is a string that contains a comma-separated list of the values that you want to initialise the int array with. Floating-point numbers are rounded down to the nearest integer. Any na values are preserved. Spaces are disregarded. @returns Returns a float array of arbitrary length. V1 includes functions for bools, floats, and ints. I might extend it if people want.
