Show your villain personally doing something despicable. Have the villain do something awful to something or someone we care about. Make sure your villain has a believable motive or agenda. Avoid bargain bin Nazis. Don't have your villain talk like a cheeseball. Be careful with those smirks.
A simple moving average is customizable in that it can be calculated for a different number of time periods, simply by adding the closing price of the security for a number of time periods and then dividing this total by the number of time periods, which gives the average price of the security over the time period.
Determine the time interval of the moving average you want to calculate, such as a three-month or six-month moving average. Go to the last value of the first interval and click on the corresponding empty cell to the right.sing the example from Step 1, if you want to calculate a three-month moving average, you would click on cell C3 because B3 contains the last value of the first three months of the year. Use the AVERAGE function and type a formula into the empty cell you selected, specifying the data range for the first interval.
