My question is in regards to calculating relative strength of security compared to S&P500.
First, how does the AFL function RelStrength work? If I enter RelStrength(MSFT), what exactly is calculated. I understand there are an infinite number ways to calculate relative strength. For this example, assume I have two arrays (S&P500 and other security). S&P500 data goes back to 09/01/1988 and other security goes back to certain date later than 1988. If I want to calculate relative strength based on the date of the last quote for the 'other security' as follows: Relative Strength = (Pt/Mt) / (P0/M0) where Pt is the security's price, Mt is the S&P500's value and P0 and M0 are the initial values (very 1st quote for security). How do I determine P0, and then look the same number of bars back for S&P500. I would like to do this for a number securities, so the date of the 1st quote will always be different. Thanks Levi
