database schema

quick start

In all samples we use sqlite but you are free to use other providers. For more information's please read Connecting to the Database.

Install sqlite stock db:

import logging
from pystockdb.tools.create import CreateAndFillDataBase

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

import logging
from pystockdb.tools.create import CreateAndFillDataBase

logger = logging.getLogger('test')
config = {
    'max_history': 1,
    'indices': ['DAX'],
    'currencies': ['EUR'],
    'create': True,
    'db_args': {
        'provider': 'mysql',
        'host': '127.0.0.1',
        'user': 'root',
        '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
    )
