I was just checking out the Correlation Table Tool provided here at mataf and under the table it was explaining how it is calculated. At a point it says: The length of the series is given by the "Num Period" field.
What exactly does that mean? I can't find any "Num Period" field on the page to make any sense with what price it uses for "Num Period"
As far as I know, correlations to be calculated need a period. For example ""50"" meaning correlation between 2 currency pairs in the last 50 candles of a selected timeframe.
I understand that the table shows the correlations in real time on the different tiemframes but at what period? I don't understand well the "Num Period" field that it's saying in "How is it calculated"
