ibstract

PyVersion PyPiVersion Status License

ibstract is a Python 3 package for trading data acquiring and management. Thanks to Python's asyncio library, it can accesses Interactive Brokers API for concurrent remote data downloading, and a MySQL database as local cache for concurrent data archiving and offline query. Classes in the package also combine, transform, and maintain trading data, and provide organized and aggregated data or signals for algorithmic trading. ibstract users can focus on trading algorithms without worrying about the hassels of handling a broker API or the tedious and error-prone trading data management.

Features

  • Concurrent data acquiring and processing with asynchronous access to remote IB API server and local MySQL database, powered by async/await syntax of asyncio module in Python 3.6+ and 3rd-party aio-libs.
  • Automatically analyze and split a user's historical data request, and dispatch data acquiring tasks to local MySQL database (preferred) or remote IB API server. In this way much downloading efforts could be saved for repeating requests for the same data pieces.
  • MarketDataBlock class manages and merges historical data pieces with different symbols, types, durations and date/time in an organized and standardized way. Data time zone is region-based using pytz, and automatically converted and maintained.

Planned Features:

  • Asynchronously generating technical signals from user-specified historical data.
  • Concurrent real-time market data streaming and real-time trading signal generating.
  • Background order submission, status monitoring, and logging.

Installation

pip3 install -U ibstract

Examples

For full explanation and detailed examples, please take a look at the example notebooks:

Example 1: Concurrently acquire data from local MySql database and remote IB API server.

A user coroutine requests wider range of historical data than those existing in MySQL. The data pieces existing in MySQL will not be downloaded, but will be queried and combined with those downloaded. A request could be split into multiple downloading tasks and perfored concurrently and asynchronously, as well as inserting the downloaded data to MySQL in the background.

Data pre-existing in MySQL database:

opening    high     low  closing  volume  barcount average

Request for wider range of data:

async def user_coro(req, broker, mysql):
    blk_ret = await get_hist_data(req, broker, mysql)
    return blk_ret

# Request daily data of 8 days, from 8/29 - 9/8.
# Data from 8/31 - 9/5 exist in local database and will not be downloaded.
req = HistDataReq('Stock', 'GS', '1d', '8d', dtest(2017, 9, 9))
broker = IB('127.0.0.1', 4002)
db_info = {'host': '127.0.0.1', 'user': 'root', 'password': 'ibstract',
           'db': 'ibstract_test'}

loop = asyncio.get_event_loop()
mysql={**db_info, 'loop': loop}
blk_ret = loop.run_until_complete(user_coro(req, broker, mysql))
blk_ret.df

Output data is the combination of those in database and downloaded:

MarketDatablock organizes DataFrames together:

import pytz
from ibstract import MarketDataBlock

east = pytz.timezone('US/Eastern')

blk = MarketDataBlock(df_gs1, datatype='TRADES', tz=east)
blk.update(df_gs2, datatype='TRADES', tz=east)
blk.update(df_fb5m, symbol='FB', datatype='TRADES', barsize='5m', tz=east)
blk.update(df_fb1m, symbol='FB', datatype='TRADES', barsize='1m', tz=east)
blk_amzn = MarketDataBlock(df_amzn, datatype='TRADES', tz=east)
blk.combine(blk_amzn)

Output MarketDataBlock: :
