1. Can be done in many ways. The easiest could be to define a format and import an ASCII-file. Separator - space or coma. Eg.:
BHP, BBL, ratio, 2., 0., 10, 5, etc.
PEP, KO, kalman, , , , etc.
After imported normal visualization occurs and user can still go through and check if everything is ok.
Your data bank is great but I also prefer to do automatic sorting and additional optimization. That is the reason.
3. Yes, you are right.
Thanks
