The Percentage Price Oscillator (PPO) expresses the difference between two moving averages as a percentage of the longer average, making it easier to compare momentum across securities with different price levels. Signal-line crossovers and histogram direction changes provide actionable buy and sell signals, similar to MACD but normalized for cross-asset comparison.
This sample renders HPE daily candlestick data on the main plot and displays the PPO indicator in a second subplot. The histogram series uses an ordinal color scale that colors bars red (#FC1F28) when below zero and cyan (#4ED1FC) when above zero for clear visual momentum reading. A column scroller provides full-range context. The chart includes a range picker and a range selector, with the default view from April to July 2019.
