In volatile situations such as the stock market, sales, tourism and travel, such an assumption must be viewed with some caution. Note that each point on the moving average is plotted as the middle of the three years with respect to the X axis. This also reflects the fact that we have chosen to use an odd number to work out our averages. This article has shown how to calculate trends, analyse them and use them to make forecasts for the future.

Oftentimes traders will trade only in the direction of the trend as determined by the moving average, or a set of them. For example, if 50-, 100-, and 200-period moving averages are all in alignment as positive sloped, the trader may bias all his or her positions to the long side. And some combine various moving averages and use crossovers of different ones to confirm trend shifts and entry points. But like all indicators, there should be confluence among different tools and modes of analysis to increase the probability of any given trade working out.

A moving average is a trend-following indicator based on past prices. Past performance is no guarantee of the future – Changes in the market or fashions and trends may cause a change in sales differing from past sales. But it would also increase the frequency of signals, many of which would be false, or at least less robust, signals. Like many things, there is a trade-off to be considered when adjusting the periods of the moving averages.

Introduction to time series forecasting using examples of moving average forecasting. We attempt to forecast the price of Gold using the GLD ETF as a proxy for the price of gold. Includes a discussion of commonly used error measures, mean absolute deviation , mean squared error and mean absolute percent error . Error measures are used to determine how good your forecast is, in other words, they measure how far off your forecast is on average.
