This study is a version of the Exponential Moving Average using calculation mechanism prior to November 13, 2010. Its difference from the updated EMA is in the way the initialization point is determined. For the Legacy EMA, the specified price of the first bar is considered the initial value, while the updated EMA study comprises historical data prefetching for that purpose. The absence of the prefetching mechanism makes the Legacy EMA study highly range-dependent.
