Nadaraya-Watson Envelope is a regression-based envelope indicator. It builds an ultra-smooth trend curve by weighting each bar with a Gaussian kernel — closer bars have more influence, distant bars less. An envelope channel is drawn around the curve: the upper band marks overbought zones, the lower band marks oversold zones.
When price touches the upper band a Sell 🔴 arrow appears, when it touches the lower band — a Buy 🟢 arrow. Pop-up alerts are supported.
Parameters: Window Size, Bandwidth, Multiplier, Source, Arrow Distance.
