# Limit the output of financial indicators list

Imagine I have a list of Forex data as below:

data= {{"2014 06 30  07:49", {1.36535, 1.36525, 1.36543, 1.36542, 81}},
{"2014 06 30  07:50", {1.36543, 1.3654, 1.36545, 1.36544, 25}},
{"2014 06 30  07:51", {1.36544, 1.36544, 1.36562, 1.36552, 116}}


The list has different sizes in different case. Then using FinancialIndicator["WildersMovingAverage", i][data] you can get a list of WildersMovingAverage given period i. The output of this function is a list.

My question is how one may limit the function in order to just compute the value of WildersMovingAverage for last data point and not to compute the whole list which is time consuming when the list is huge?

That is, the second argument is the number of periods used in calculating the moving average. So, we can pass the last n periods of the data to the function FinancialIndicator["WildersMovingAverage", n] to get the "last" value of the indicator:
 data = FinancialData["MSFT", {{2009, 1, 1}, {2009, 3, 31}}];
