Momentum between times

tsmom has been partially removed and will no longer accept a fints object (tsobj) argument. Use a vector, matrix, timetable, or table instead for financial time series.

Use fts2timetable to convert a fints object to a timetable object.


momentum = tsmom(Data)
momentum = tsmom(___,Name,Value)



momentum = tsmom(Data) calculates the momentum of a data series with time distance of n periods.


momentum = tsmom(___,Name,Value) adds optional name-value pair arguments.

Load the file SimulatedStock.mat, which provides a timetable (TMW) for financial data for TMW stock.

load SimulatedStock.mat
TMW.Volume = []; % remove VOLUME field
momentum = tsmom(TMW);  
title('Acceleration for TMW')

Input Arguments

collapse all

Data with high, low, open, close information, specified as a vector, matrix, table, or timetable. For vector input, Data is a column vector. For matrix input, Data is an M-by-N column oriented matrix. Timetables and tables with M rows can contain variables named 'High', 'Low', 'Open', and 'Close' (case insensitive).

Data Types: double | table | timetable

Name-Value Pair Arguments

Specify optional comma-separated pairs of Name,Value arguments. Name is the argument name and Value is the corresponding value. Name must appear inside single quotes (' '). You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: momentum = tsmom(TMW,'NumPeriods',15)

collapse all

Period difference for momentum, specified as the comma-separated pair consisting of 'NumPeriods' and a scalar positive integer.

Data Types: double

Output Arguments

collapse all

Momentum series, returned with the same number of rows (M) and the same type (matrix, table, or timetable) as the input Data.

More About

Momentum Series

Momentum series is the difference of the current data with the data n periods ago. By default, momentum is based on 12-period difference.
