[EquisMetaStock Group] Can we plot the beta of stock in Metastock?

["ktlau858" <ktlau858@xxxxxxxxx>]

Dear all,
Is it possible to code the 30-day beta as an indicator in metastock using covariance and variance function?

Precisely, the 30-day beta of a stock is covariance(index, stock)/variance(index); where
index=price array of a market index which contain 30 days of data, and
stock=price array of a stock, which also contain 30days of data.

Thank you very much in advance..

Tony
