Tomasz Two questions:
1. Can we create a time-series of user defined fundamental fields? if not, please explain why not? 2. What is the cost of two additional auxilliary data fields in terms of overhead and computing power? I can see using one for dividend and the other for split information. I could use a couple more. One for tagging symbols for material events (such as merger & bankrupcy).
