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,...

This is a script to draw a square wave on the chart, with an indicator for current price. Markets undergoing Dow Jones or Wyckoff Accumulation/Distribution cycles tend to move in such waves, and if the period of the cycles are detected, a signal for accumulation/distribution phases can be created as an early warning. Useful inputs: - Average True Range as the...

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 =...

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...
