Source Code
The code stays on GitHub. The author has not published this script under an open licence, so ForexR does not show its code. Copy script reads the file straight from GitHub into your clipboard, so you can still try it on your own chart. Ask the author before reusing the code anywhere else.
Overview
Forecasting: Holt's Linear Trend Forecasting continuously calculates recursive level and trend estimates governed by user-defined alpha and beta smoothing parameters. The script projects a dynamic line into future bars starting from the latest close price toward the forecasted price level. Traders can adjust the source price input along with the level and trend smoothing factors directly from the settings pane to refine responsiveness.
