Overview
Performance is measured over the four quarters of a year with the most recent quarter weighted more, and falls back to recent quarters when a full year of data is missing. The difference is drawn as a filled histogram-style area, green when the symbol is stronger and red when weaker, with a one-year moving average line. Colours and the reference are adjustable. It suits daily and weekly charts.
The inputs you can change from the gear icon on the chart. Defaults are the author's.

Asymmetrical RSI is an indicator that computes a custom relative strength index from the rate of change of a user-selected source. It plots the resulting ARSI line in a separate pane with color coding that turns green above the overbought level and red below t
This indicator calculates momentum setups based on the Relative Strength Index (RSI) and plots in a separate pane. It offers multiple scanning modes such as Continuous Break, Continuous Retracement, Flip Break, Flip Retracement, and both regular and hidden div
This indicator calculates a modified MACD oscillator and signal line alongside a trend EMA filter, plotting the output as a stylized column histogram in a separate pane. Instead of plotting true MACD distance, it quantifies positive and negative histogram mome
This indicator plots the Average Directional Index in a separate pane and colors the line teal or maroon according to whether plus DI is above minus DI. A horizontal key level and a silver background mark periods when ADX exceeds that threshold. With labels en
This indicator demonstrates an experimental graph-style scatter visualization within a separate pane using Pine Script arrays. It tracks two features across recent bars: the single-bar price change and a scaled 14-period Relative Strength Index. Values are loa
This script calculates and plots a Stochastic Oscillator (KD indicator) in a separate chart pane. It determines the fast stochastic value over a 9-period lookback, then applies a 3-period Simple Moving Average (SMA) to create the %K line, and a second 3-period
