Aggregation
The Aggregation function is used to aggregate the values of multiple numeric columns. The output of this function is a column with its values coming from the selected columns.
The inputs of this function are:
Timeframes: The timeframes in which the function is applied
Lines: To-be-aggregated columns. (Only numeric columns can be used)
Aggregation Method: The method used to aggregate the columns; This could be Max, Min, and Mean
Output Column Name(s): The name of the column in which the result is stored
Example
Sometimes, traders use the middle point in the bodies of candles to judge the markets. To obtain the middle price in candles, we add the open and close prices and use the Aggregation function to find the middle price between the open and close prices, which is the middle of the candles. The configuration of the Aggregation is shown below:
The result of the aggregation is illustrated in the figure below:
As is seen in the table, the middle_of_canldes contains the mean value of the open and the close columns. You can use Maximum and Minimum to obtain the maximum or minimum values of two or more columns in the same manner.
