MetaData Initialization
Allowed instruments types are given in "Instrument Types" section of meta_enumerations.md.
Data Initialization for Instrument Type(s)
from trade_database_manager.manager import MetadataSql
metadatalib = MetadataSql()
metadatalib.initialize(for_inst_types="CB")
This will try to create two tables, instruments and instruments_cb in the database if not yet exists. The instruments table will store the common information of all instruments, and the instruments_cb table will store the type-specific information of the instruments of type CB.
The table fields are listed in the data_organization.md file.
