# Function mode The function mode is focused on making it **easy**, **fast** and **intuitive** to create the indices which give insights of the market, by combining **time-series data** and **functions** that execute mathematical calculations. Compared to the **python mode**, function mode can calculate time-series data and get the technical indicators from the market data **easily** without any coding technics such as handling loop. However, if you want to apply some complex calculations based on probabilistic or numerical methods, you are advised to use python mode. ## Contents * [1.
