You can do that in two ways,
you can store the historical bid/ask arrays just like any persistent
variables, in a text file which you will read and load into AB. it
would be a bit slow.
or you can store it as a binary file using a dll, and read it into
back into memory when required, that is considerably faster, though
not quite as fast as accessing the price fields.
