tsaccel

Acceleration between times

Using a fints object for the Data argument of tsaccel is not recommended. Use a vector, matrix, timetable, or table instead for financial time series. For more information, see Convert Financial Time Series Objects fints to Timetables.

Syntax

acceleration = tsaccel(Data)

acceleration = tsaccel(___,Name,Value)

Description

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

n periods.

acceleration = tsaccel(___,Name,Value) adds optional name-value pair arguments.

Examples

Calculate the Acceleration of a Data Series for a Stock

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

load SimulatedStock.mat
TMW.Volume = []; % remove VOLUME field
acceleration = tsaccel(TMW);  
plot(acceleration.Time,acceleration.Variables)
legend('OPEN','HIGH','LOW','CLOSE')
title('Acceleration for TMW')

Input Arguments

Data — Data with high, low, open, close information

vector | matrix | table | timetable

Data with high, low, open, close information, specified as a vector, matrix, table, or timetable. For vector input, Data is a column vector of high, low, open, and closing prices stored in the corresponding columns. For matrix input, Data is an M-by-N column-oriented matrix of high, low, open, and closing prices stored in the corresponding columns. Timetables and tables with M rows must 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 quotes. You can specify several name and value pair arguments in any order as Name1,Value1,...,NameN,ValueN.

Example: accelearation = tsaccel(TMW,'NumPeriods',10,'Datatype',1)

'NumPeriods' — Period difference for acceleration

12 (default) | positive integer

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

Data Types: double

'Datatype' — Indicates if Data contains the data itself or the momentum of the data

0 (Data contains the data itself) (default) | integer with values 0 or 1

Indicates if Data contains the data itself or the momentum of the data, specified as the comma-separated pair consisting of 'Datatype' and a scalar integer with a value of:

• 0 – Data contains the data itself.

• 1 – Data contains the momentum of the data.

Data Types: double

Output Arguments

acceleration — Acceleration series

vector | matrix | table | timetable

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

More About

Acceleration

Acceleration is defined as the difference of two momentum series separated by n periods.

Acceleration is the difference of the current momentum with the momentum n periods ago. By default, acceleration is based on 12-period difference.
