# How to calculate 5 EMA

I am trying to understand the basics of finance indicators. I have made 15 minute ohlc candles for the past 50 days.

Now if I try to calculate 5EMA, my doubt is what does 5 refer to? Is it days of number of candles or number of days? Assuming 6 hour trading session, I will have 1200 candles (50 days, 6 hours each day,15 min candles ). So, if I say my period is 5, is it number of candles or number of days?

If it is number of days (which I am usually coming acroos various tutorials, how do I convert these days to number of candles?)

Please don't branch off the discussions whether EMA is profitable or not.

Thanks
