ib_async Changelog

2.0

Version 2.0.1 (2025-06-22)

Minor dependency change to fix pypi package building.

Dependency Fix

The eventkit dependency is now aeventkit because eventkit is locked behind a closed account and pypi doesn’t allow dependencies with direct github URL tags.

Version 2.0.0 (2025-06-13)

This major release includes significant new features, performance improvements, and critical bug fixes. The most notable addition is the custom defaults system, allowing users to customize how ib_async handles empty values and timestamps throughout the library.

Added

  • Custom Default Values: Major new feature allowing customization of default values used throughout the library via IBDefaults object passed to IB() constructor

    • Customize emptyPrice, emptySize, unset values, and timezone settings

    • Replace IBKR’s default values (emptyPrice=-1, emptySize=0, unset=nan) with your preferred defaults (e.g., None)

    • Set custom timezone for timestamp display (e.g., pytz.timezone("US/Eastern") instead of UTC)

  • Enhanced Ticker Data: New ticker fields for improved market data analysis

    • timestamp: Float format timestamp for easier mathematical operations alongside existing time field

    • shortable: Shortability score (0-3) for instruments

    • volumeRate3Min, volumeRate5Min, volumeRate10Min: IBKR-provided volume acceleration metrics

    • lastTimestamp: Timestamp of the last trade event

  • OrderStatus Enhancements: Extended order management capabilities

    • New API status states added to OrderStatus enum

    • totalQuantity() method to report total order quantity

    • Additional helper methods for reading order states

  • OrderState Conversion Helpers: New utility methods for OrderState objects

    • numeric(): Convert string values to numbers with optional digit rounding

    • formatted(): Convert values to comma-separated formatted strings

    • Both methods handle UNSET_DOUBLE values automatically

  • OptionComputation Mathematical Operations: Options can now be added, subtracted, and multiplied

    • Enables direct calculation of Greeks for spreads (e.g., vertical spreads: longGreeks - shortGreeks)

  • Contract-from-params Abstraction: Centralized logic for converting generic Contract objects to specific subclass types (e.g., Contract(secType="OPT") → Option())

  • Enhanced Contract Support:

    • Event Contracts (“EC” security type) recognition for binary event betting

    • Bag contracts can now be hashed using leg details, symbol, and exchange

  • Improved Market Data Subscription Management:

    • cancelMktData() now returns success/failure status instead of just logging

    • Contract lookups now use hash(contract) instead of id(contract), allowing reuse of equivalent contract objects

Changed

  • Breaking: qualifyContractsAsync() behavior significantly improved

    • Now returns N results for N input contracts (previously returned fewer results if some failed)

    • Failed qualifications return None in corresponding position

    • New returnAll parameter: when True, returns all possible matches as a list instead of failing for ambiguous contracts

    • Enables reliable zip(requestContracts, resultContracts) usage

  • Ticker Previous Value Logic: Simplified and more accurate tracking

    • Previous price/size now always reflects the truly previous values, regardless of whether they match current values

    • Removed conditional updating that caused inaccurate “previous” data representation

    • Better performance by eliminating unnecessary comparisons

  • Type System Modernization: Extensive type annotation improvements

    • Dict → dict, List → list, FrozenSet → frozenset throughout codebase

    • Enhanced Order class with proper type annotations and Decimal support for price/quantity fields

    • Converted NamedTuple instances to frozen dataclasses for better extensibility

  • Event Loop Handling: Updated for modern Python compatibility (recent asyncio API changes)

Fixed

  • Critical Order Management Bug: Fixed order cache deletion issues that caused “phantom orders”

    • Orders are no longer incorrectly deleted from client state when modification validation fails

    • Warning messages are now logged to order history instead of causing state corruption

    • Prevents situation where orders appear cancelled locally but remain active at broker

  • Order Modification Bug Prevention: Added API-level validation to prevent common modification errors

    • Automatic handling of IBKR API field overwrites that conflict with user data

    • Prevents submission of unintended order updates from cached order objects

  • TWS API Contract Matching Bug Workaround: Fixed cross-instrument contract suggestions

    • When requesting FOP contracts, IBKR was incorrectly also returning Event Contracts

    • Now filters results to only return contracts matching the requested security type

  • Bulk Data Tick Types: Fixed default value handling in bulk tick processing

  • Last Trade Timestamp Validation: Improved handling of invalid ‘0’ timestamps from ticker startup

  • Volatility Order Type: Corrected “VOL” → “VOLAT” order type specification

  • Missing Import: Added missing import that was causing import errors

  • False Order Cache Deletion: Additional fix for orders being incorrectly removed during modification validation

Performance

  • Tick Processing Optimization: Significant performance improvements for market data handling

    • Replaced multi-case if/else branches with lookup maps for tick type processing

    • More efficient handling of generic ticks and Greek ticks

    • Added explicit error handling for unknown tick types to aid future development

  • Ticker Update Performance: Eliminated unnecessary comparison operations during ticker updates

    • Always replace fields instead of conditionally checking for changes

    • Faster processing of instruments with frequent same-price trades

Developer Experience

  • Enhanced Error Handling: Better error messages and logging throughout

    • Unknown tick types now generate explicit error messages for easier debugging

    • More verbose validation error reporting

  • Code Style: Comprehensive formatting and linting improvements

    • Applied ruff format and ufmt formatting across entire codebase

    • Fixed various style warnings and modernized code patterns

    • Variable naming improvements (fixed illegal variable names like ‘l’)

Internal

  • Disconnection Logic: Improved connection state management

    • Full state reset on disconnect/reconnect cycles

    • Returns connection status string with session details

  • Utility Functions: Modernized util.py with updated Python patterns and async compatibility

Migration Notes for v2.0.0:

  1. qualifyContractsAsync() users: The return value now always contains the same number of elements as input contracts. Check for None values to detect failed qualifications.

  2. Custom defaults users: Consider using IBDefaults() to customize empty values if you’ve been manually handling -1 prices or 0 sizes.

  3. Ticker previous value users: The logic for previousPrice/previousSize is now more accurate but may show different values if you were relying on the old conditional update behavior.

  4. Order management users: Order validation errors are now logged to order history instead of causing order deletions. Check order event logs for validation details.

1.0

Version 1.0.3 (2024-07-06)

General improvements and minor correctness fixes.

  • Fixed issue 42: Order preview requests would often fail for non-limit-order types due to incorrect value comparison. This has previous attempted fixes over the years, but we finally found the proper fix to the other fixes. Now order preview requests work properly for all order types.

  • Now market depth data is removed from the Ticker object when a market depth request is stopped because the data isn’t being live updated anymore.

  • Added ib_fundamental to community utility listing in README

Version 1.0.2 (2024-06-29)

General improvements and minor correctness fixes.

  • Fixed issue 28: Add ability to optionally disable account data synchronization on startup. If you are an advanced user, you may not need all your data synchronized on startup (which can slow down the initial connections due to the multiple sequential request loading) or you may want to control when the account data is loaded on your own schedule.

  • Fixed issue 33: Improved reliability of L2 depth of market reporting

  • Fixed issue 10 and issue 11: Fixed links in documentation

  • Fixed issue 16: Fixed documentation typo

  • Fixed issue 32: Use delayed data instead of denied data in example notebooks

  • Improved error logging if a wrapped method fails

  • Removed a potential exception when shutting down the event loop from within a larger system

Version 1.0.1 (2024-03-20)

  • Fixed issue 4: Messaging sending bug for unresolved contracts due to cleanup in 1.0.0

Solved this messaging sending bug by refactoring message parsing logic to be more stable. Also added a test case verifying it works as expected now.

Version 1.0.0 (2024-03-18)

This is the first version under new management after the unexpected passing of Ewald de Wit on March 11, 2024. We wish to maintain his legacy while continuing to improve the project going forward. We are resetting the project name, development practices, modernization levels, and project structure to hopefully grow more contributors over time.

This version update does not include any feature improvements and is functionally equivalent to the final version of ib_insync 0.9.86.

Code Cleanup:

  • Reformatted all code with ruff and improved readability throughout

  • Now uses sets for membership checking everywhere

  • Fixed a technical error around API message formatting

Project Changes:

  • Renamed ib_insync to ib_async everywhere

  • Increased minimum Python version from 3.6 (2016) to 3.10 (2021)

  • Removed dependencies for supporting Python versions less than 3.9

  • Converted README.rst to README.md

  • Updated IBKR API links to new ibkrcampus instead of old github docs

  • Removed setup.{py,cfg} to use Poetry for installing, docs, packaging

  • Converted links from /erdewit/ account to new /ib-api-reloaded/ org

  • Removed helper scripts for packaging and building docs

  • Removed docs-generated HTML from repository

  • Auto-build docs and update github docs site on every push

  • Documentation now auto-builds and is hosted on github pages instead of readthedocs

Original ib_insync Changelog (2017-2023)

Note: due to the project moving to a github organization, all auto-generated links below to mentioned issues and PRs don’t work anymore. You can use the issue numbers in the original ib_insync repo for historical reference.
