Source Code

Overview
Forecasting: Quadratic Regression fits a parabolic trend line over a specified lookback window and projects future trajectory onto the chart using a seasonal naive forecasting method. The script plots the fitted regression curve on the main price chart and draws a dynamic line projecting into future periods based on user inputs for lookback window, season length, and forecasted periods.

Indicators describe the past, and a strategy's backtest can look better than live trading, especially when a script repaints.
