This add-on provides a library of in-cell functions for common technical indicators, removing the need to build complex formulas yourself.
You can reference price data in your sheet and apply calculations such as RSI, MACD, Bollinger Bands, moving averages, and more without external tools or scripts.
Each function is designed to return clean, reliable results that update automatically as your data changes, making it easier to analyze trends, test strategies, or keep watchlists current.
