Traders started to argue that the most recent development has the right to influence our averages more than the older data points. Many traders asked themselves why older price points were given the same weightage as new price points in the simple moving average. Now, If you think about it the simple moving averages gives the same ‘weight’ or importance to each new data point equally. For instance intraday traders may look to buy the cross over of the 10 period and 20 period average on the 10 20min timeframe while the investor may look for some buying pressure to arise at the touch of the 200 MA on the daily charts. The moving average is not restricted to only daily charts, they can be used on any timeframe and are useful for intraday traders as well as investors simply by changing the timeframe. If you were wondering why we call this a “moving” average and not just mean of prices it is because as new days are added, previous data sets are dropped to include the new data and the average is constantly ‘moving’. When a new day is added then we have 2 points, and the calculation is done every time a new data set arises, eventually making a blue line you see in the charts above. This of course gives us a single average point. To calculate a 21 day simple moving average, simply add the closing prices of the last 21 days and divide by 21. Lucky you?
