This Pine Script implements a Gaussian Channel + Stochastic RSI Strategy for TradingView. It calculates a Gaussian Weighted Moving Average (GWMA) and its standard deviation to form an upper and lower channel. A Stochastic RSI is also computed to determine momentum. A long position is entered when the price closes above the upper Gaussian band and the Stoch RSI K-line crosses above D-line. The position is exited when the price falls back below the upper band. The script includes commission, capital management, and date filtering.

here is the code
