prcroc

Price rate of change

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

Description

example

PriceChangeRate = prcroc(Data) calculates the price rate-of-change, PriceChangeRate, from the series of closing stock prices. By default, the volume rate-of-change is calculated between the current closing price and the closing price 12 periods ago.

example

PriceChangeRate = prcroc(___,Name,Value) adds optional name-value pair arguments.

Examples

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

load SimulatedStock.mat
PriceChangeRate = prcroc(TMW);
plot(PriceChangeRate.Time,PriceChangeRate.PriceRoc)
title('Price Rate of Change for TMW')

Figure contains an axes object. The axes object with title Price Rate of Change for TMW contains an object of type line.
