A couple of simple questions concerning moving averages.

In Lean Docs it states, that EMA is the traditional exponential moving average indicator. What makes it traditional? Being based on Close prices?

And in EMA method:

public ExponentialMovingAverage EMA( Symbol symbol, int period)

is period equivalent to 1 Bar? if I am using 5-min data, is period of 1 equal to one 5-min ?

See my project with EMA-8 and SMA-40 with intraday data. I just want to make sure it is done correctly.
