Hi fourpeaks99,
Thank you for you post.
The Exponential Moving Average is an indicator that shows the average value of a security's price over a period of time. When calculating a moving average. The EMA applies more weight to recent prices than the SMA. (http://www.ninjatrader-support.com/H...verageEMA.html)
Input[0] * (2.0 / (1 + Period)) + (1 - (2.0 / (1 + Period))) * Value[1]
Where...
Input[0] = is the close of the current bar in most cases
Value[1] = the value of the EMA calculated one bar prior
The WMA (Weighted Moving Average) is a Moving Average indicator that shows the average value of a security's price over a period of time with special emphasis on the more recent portions of the time period under analysis as opposed to the earlier. (http://www.ninjatrader-support.com/H...verageWMA.html)
The calculation here is more involved but you can view it by navigating to "Tools>Edit NS>Indicators"TimNinjaTrader Customer Service

Also, does Ninjatrader only use the data on the chart to calculate the moving average? For instance, if i have a chart with a start point of 1/1/10 will Ninjatrader use data from 2009 to create the moving average or will it use data starting from 1/1/10?
