works with protobuf ONLY, requires 10.40 or greater
replaces wrapper._results with a reactive pipeline implemented in eventkit. This simplifies the solution by removing state management

simple test script

import logging
import ib_async


ib_async.util.startLoop()
logging.basicConfig(
    level=logging.DEBUG,
    format='%(asctime)s %(levelname)s %(name)s: %(message)s',
    filename='debug_connection.log',
    filemode='w')
ib = ib_async.IB()

ib.connect('localhost',7497,clientId=0)
print("connection completed")

aapl = ib_async.Stock("AAPL",'SMART','USD')
aapl_details = ib.reqContractDetails(aapl)
print(aapl)
print(aapl_details)

ib.disconnect()
print("disconnected.")

Still a long way to go, but I wanted to share a version that can connect, sync account related objects and perform some basic requests and disconnect.

I'm working on:

  • reqHistoricalData, working for one-off requests. Subscription pending
  • reqHistoricalTicks,
  • reqHeadTimeStamp
  • reqHistogramData
  • reqHistoricalSchedule
  • placeOrder
  • tests: i have a few tests in place. i need to do some clean-up and i will push.

Next level of complexity:

  • reqMktData,
  • reqMktDepth,
  • reqRealTimeBars,
  • reqScannerSubscription,
  • reqPnL,
  • reqPnLSingle.

- Added logging for ticker data reception and processing.
- Introduced new methods in Ticker class for handling various tick data types (price, size, string, generic, computation).
- Updated Wrapper class to emit events for tick data using a bus system.
- Removed redundant tick type mappings and replaced them with more structured handling.
- Enhanced error handling for malformed tick data.
- Improved readability and maintainability of the code by organizing tick data processing logic.
