There is a parameter for each symbol, Symbol > Information > Use only local database, yes or no. But that will only keep the data from being back filled if set to yes and you may not want to do that. If I read your note right you want to import the data into AB and then keep it updated from some data source, maybe FT. If so the parameter has to be set to no.
How did you copy or import the FT data into AB? AB is kind of fussy about what you put in their database. If you import the data incorrectly it will blow up every time you try to use the symbol. What do you want to write into the OI field? When are you trying to write it?
