Source Code

Overview
[Sapphire] JetStream (SWMA + Laguerre Filter) can mark strong signals when both are aligned and weaker signals based on the SWMA alone, and it can recolor candles as strong bullish, strong bearish, or neutral. Length, source, Laguerre alpha, plot visibility, and colors are adjustable. Bar coloring can change on the live bar when the repaint option is left on.
