logger = logging.getLogger('test')
config = {
'max_history': 1,
'indices': ['DAX'],
'currencies': ['EUR'],
'create': True,
'db_args': {
'provider': 'sqlite',
'filename': 'demo.sqlite',
'create_db': True
},
}
create = CreateAndFillDataBase(config, logger)
create.build()
Install mysql stock db:
For mysql you need an additional package:
pip install pymysql

'db_args': {
'provider': 'mysql',
'host': '127.0.0.1',

'passwd': 'test',
'db': 'test',
},
}
create = CreateAndFillDataBase(config, logger)
create.build()
Update sqlite stock db:
import logging
from pystockdb.tools import ALL_SYMBOLS
from pystockdb.tools.update import UpdateDataBaseStocks
logger = logging.getLogger('test')
config = {
'symbols': [ALL_SYMBOLS],
'prices': True, # update prices
'fundamentals': True, # update fundamental stock data
'db_args': {
'provider': 'sqlite',
'filename': 'demo.sqlite',
'create_db': False
},
}
update = UpdateDataBaseStocks(config, logger)
update.build()
Sync sqlite stock db:
import logging
from pystockdb.tools.sync import SyncDataBaseStocks
logger = logging.getLogger('test')
config = {
'max_history': 1,
'indices': ['CAC 40'], # add new index to existing database
'currencies': ['EUR'],
'db_args': {
'provider': 'sqlite',
'filename': 'demo.sqlite',
},
}
sync = SyncDataBaseStocks(config, logger)
sync.build()
Getting database objects:
import datetime
from pony.orm import db_session
from pystockdb.db.schema.stocks import Price, Stock
from pystockdb.tools.base import DBBase
# connect to database
arguments = {
'db_args': {
'provider': 'sqlite',
'filename': 'test.sqlite',
'create_db': False
}
}
# Read https://docs.ponyorm.org/api_reference.html for other provider settings
DBBase(arguments, None)
now = datetime.datetime.now()
last_week = now - datetime.timedelta(days=7)
with db_session:
# get ifx stock object
stock = Stock.select(
(lambda s: 'IFX.F' in s.price_item.symbols.name)
).first()
# select ifx.f prices of the last week
prices = Price.select(
lambda p: p.symbol.name == 'IFX.F'
and p.date >= last_week
and p.date <= now
)
