I would like to purchase the EDI historical data package for 10 exchanges but had a question on the pricing of the extension pack.
Does the extension pack cost become prorated on a daily basis if I come back to purchase an extension before a whole month has elapsed since my last purchase? Or is it limited to one month blocks of data?
For example, if I purchase the full database on October 1st and come back on November 15th to purchase an extension, would it cost one and a half times the monthly price of the extension pack?
Thank you
