[EquisMetaStock Group] Sign of Open Interest Change

["Alex Spiroglou" <a.spiroglou@xxxxxxxxx>]

Dear Listmembers,

 

I am trying to build an indicator that includes

a comparison of the change in Open Interest.

 

COI = Change in Open Interest (+ or -)

 

How could I have the COI as negative or positive

compared to the previous day, without the actual value ?

 

i.e today OI = 100,000

    yestredray OI = 150,000

    the COI = -   

    (not -50,000)

 

thanks in advance

Alex
