Using more than one parameter for sec

["Moshe Shalom" <moshe_shalom@xxxxxxxxxx>]

Dear and Knowledgeable Members,

I am using the Open Interests field of the securities to store the number of
transactions performed so that I can use it for analysis later. How can I
create more parameters like that attached to a security for further use. For
example, Pos/Nag surplus at Open, no of transactions made at open price
etc...

I need to make the data related to the securities and not create a new one
for this data.

Many thanks in advance,

Moshe Shalom
