Perfect Opens Perfect Boxes

This approach combines two methods of chart denoising:
1. The underlying chart uses the previous close as the open price for the next candle, which makes candlestick patterns easier to read.
2. The overlay reduces the visual noise of a line chart by representing the price range over a given interval as a box; the “wicks” on this chart are purely cosmetic, indicating that closing prices lay outside the range of the previous interval.
