Since your are looking at % stocks above the 20-day moving average, it
doesn't matter if the price history of a stock is 2 months or 5 years. All
you need are 40 days of prices for an EMA or 20 days of prices for a sma.
Ignore the stocks for which you have a too short price history.
Hope this helps

Subject: [EquisMetaStock Group] Multiple security indicators using "security
data" function
Hi,
I am trying to create indicators whose plot is based on a number of
securities. For eg: %of Stocks above 20-day Moving Average from, lets
say, a 50-security group. Now, the problem is the starting date of
the data for various securities. The starting date differs from
security to security. Now, whichever security among this has the
latest starting date, that much history only is plotted by
the "security data" function. For eg. one security will have a
starting date 2 months back while the rest of the 49 securities have
starting date 5 years back. Now, just because of this one security,
the history of the resultant plot is limited to 2 months.
How does one work around this problem. I will be extremely grateful
for any help on this front. This solution will open up a whole new
analytical dimension for me without needing to employ hardcore
external programming.
Thanks.
