Geometria del mercato
Esistono diversi tipi di geometria del mercato. Le Pitchforkssono uno strumento ampiamente utilizzato che, in base a un canale tracciato su pivot principali, calcola una linea mediana che fornisce una diversa prospettiva della geometria del mercato. Questa linea mediana è fondamentale, per questo motivo le pitchfork vengono spesso definite metodo della linea mediana. Per alcuni graficisti le linee rette sono troppo limitate e portano quindi la geometria del mercato a nuovi livelli usando archi, cerchi e spirali. Misurano la geometria in base al prezzo e al tempo del mercato e consentono a un trader di adeguare l'azione dei prezzi del passato e di prevedere quindi i movimenti futuri in base a un supporto, a una resistenza o a punti d'inversione potenziali.
Library "eHarmonicpatternsLogScale" Library provides functions to scan harmonic patterns both or normal and log scale getSupportedPatterns() get_prz_range(x, a, b, c, patternArray, errorPercent, start_adj, end_adj, logScale) Provides PRZ range based on BCD and XAD ranges Parameters: x : X coordinate value a : A coordinate value b : B...
Library "ZigzagObjects" User Defined Types to be used for Zigzag related libraries. This library just contain types. There be be another library ZigzagMethods which will implement using these types. Advantage of having types defined in separate library is that we do not have to update types for changing the implementation. Indicator Indicator is collection...
Library "FibRatios" Library with calculation logic for fib retracement, extension and ratios retracement(a, b, ratio, logScale, precision) Calculates the retracement for points a, b with given ratio and scale Parameters: a : Starting point a b : Second point b ratio : Ratio for which we need to calculate retracement c logScale : Flag...
Basic library for the visible range chart; with functions to allow plotting Fibs from body high/low as well as wick high/low -Thanks to code from @PineCoders Visible Chart library (PineCoders/VisibleChart/4), which is a much more comprehensive library than this, but which does not include some functions that I find useful: -Added the following exportable...
This script plots a a square composed of 8 equilateral triangles ("grid"). User can set the frequency of calculation/interval by adjusting the 't' parameter. Steps for calculating grid: 1. Find the highest high and lowest low for last 't' periods. 2. Calculate midpoint for prices during that interval (highest high + lowest low) / 2. 3. Center of the grid =...
![BTCUSDT: [e2] Drawing Library :: Horizontal Ray](https://s3.tradingview.com/w/WRHeq9cf_mid.png "[e2] Drawing Library :: Horizontal Ray")
█ OVERVIEW Library "e2hray" A drawing library that contains the hray() function, which draws a horizontal ray/s with an initial point determined by a specified condition. It plots a ray until it reached the price. The function let you control the visibility of historical levels and setup the alerts. █ HORIZONTAL RAY FUNCTION hray(condition, level, color,...
Library "rzigzag" Recursive Zigzag Using Matrix allows to create zigzags recursively on multiple levels. After bit of consideration, decided to make this public. zigzag(length, ohlc, numberOfPivots, offset) calculates plain zigzag based on input Parameters: length : Zigzag Length ohlc : Array containing ohlc values. Can also contain custom...
Library "eHarmonicpatternsExtended" Library provides an alternative method to scan harmonic patterns. This is helpful in reducing iterations. Republishing as new library instead of existing eHarmonicpatterns because I need that copy for existing scripts. scan_xab(bcdRatio, err_min, err_max, patternArray) Checks if bcd ratio is in range of any harmonic...
Library "Trig" Trigonometric functions rt_get_angleAlpha(a, b, c, deg) Get angle α of a right triangle, given the lengths of its sides Parameters: a : length of leg a (float) b : length of leg b (float) c : length of hypotenuse (float) deg : flag to return angle in degrees (bool - default = false) Returns: angle α in radians (or...
Library "MathGeometryCurvesChaikin" Implements the chaikin algorithm to create a curved path, from assigned points. chaikin(points_x, points_y, closed) Chaikin algorithm method, uses provided points to generate a smoothed path. Parameters: points_x : float array, the x value of points. points_y : float array, the y value of points. closed : bool,...
![GBPUSD: [JRL] Murrey Math Lines](https://s3.tradingview.com/x/xOcBp7hN_mid.png "[JRL] Murrey Math Lines")
Murrey Math Lines are support and resistance lines based on geometric mathematical formulas developed by T. H. Murrey. MM lines are a derivation of the observations of W.D. Gann. Murrey's geometry facilitate the use of Gann's theories in a somewhat easier application. According to Gann's theory, price tends to trend and retrace in 1/8th intervals. The most...
Library "CreateAndShowZigzag" Functions in this library creates/updates zigzag array and shows the zigzag getZigzag(zigzag, prd, max_array_size) calculates zigzag using period Parameters: zigzag : is the float array for the zigzag (should be defined like "var zigzag = array.new_float(0)"). each zigzag points contains 2 element: 1. price level of the zz...
Library "intersect" Find Line Intersection X/Y coordinates. Simple to use, will find intersection if it exists on the segments if the line segments do not cross on segment, an 'na' value will be returned if you plot new items with the output coords, they still plot. avoid this by setting a na(x) condition before plotting new items get(l1, l2, (...
Library "harmonicpatterns" harmonicpatterns: methods required for calculation of harmonic patterns. These are customised to be used in my scripts. But, also simple enough for others to make use of :) isGartleyPattern(xabRatio, abcRatio, bcdRatio, xadRatio, err_min, err_max) isGartleyPattern: Checks for harmonic pattern Gartley Parameters: xabRatio :...
Library "LineGetPriceOnLogScale" This library provides a way to calculate the y-coordinate of a line on a specified bar when the chart scale is Log. The built-in `line.get_price()` function only works with linear scale and gives incorrect results when the chart is in Log scale. The library only works with `bar_index` values and `xloc.bar_index`-based lines,...
Library "HarmonicPattern" Functions to detect/check harmonic patterns from provided values. line_price_rate(point_c, point_b, point_a) Compute the price rate of the line AB divided by the the line BC Parameters: point_c : float, the price at point C. point_b : float, the price at point B. point_a : float, the price at point A. Returns: float ...
Library "FunctionGeometricLineDrawings" array_delete_all_lines(lines) deletes all lines in array. Parameters: lines : line array, array with line objects to delete. Returns: void. triangle(sample_x, sample_y, xloc, extend, color, style, width) Draw a Triangle with 3 vector2D(x, y) coordinates. Parameters: sample_x : int array, triangle...
