The Derivative Oscillator calculates a double-exponentially smoothed Relative Strength Index (RSI) and subtracts its Simple Moving Average (SMA) to form the main oscillator line. A secondary signal line is plotted using an SMA of the main oscillator values. Th

Overview
f_push() maintains a fixed-length array of closing prices by popping the oldest value and inserting the newest close at the front index. The script plots the newest price element, an older price element offset backwards, and the simple moving average calculated from the array sum. It displays in a separate pane.
- Custom array FIFO push and pop function
- Rolling window array buffer for closing prices
- Array-based simple moving average calculation
- Configurable array length input
