Overview
When the correlation exceeds a fixed threshold, the indicator blends a simple moving average with its prior values and updates trend direction. When correlation is low, it projects the moving average along the current trend vector using step variations. It overlays directly on the price chart, plotting a color-coded moving average line and filling the gap between the source price and the moving average.
