1.2.0

  • internal architecture changes related to compatibility with PTL portfolio system
  • RSI filter for Ratio model now fully supported
  • all entry modes are now supported for Residual model

Released 2015-01-02.

1.1.1

Bugfix release & internal architecture improvements:

  • redesigned concurrency and threading architecture (pair strategies now use thread confinement)
  • fixed few potential deadlock situations and GUI freezes
  • fixed concurrency issue which could potentially lead to allow N+1 slots opened in a rare occasion
  • fixed retrying fetching historical data after IB data pacing violation (regression introduced in 1.0.4, it worked in earlier versions)

Released 2014-10-07.

1.1.0

  • basic FA (Financial Adviser) account support (you have to enter the account code manually when connecting)
  • increased log file max size and number of backups
  • unadjusted split protection (stops auto trading if there is a significant price discrepancy which may indicate that IB forgot to adjust historical data after split event)
  • prevents automated trading if historical data fetched are obsolete (older than 5 days)
  • connection to IB API is now handled in a separate thread to prevent UI freezes
  • updated IB client API files to 971.01
  • minor cosmetic changes and bugfixes
  • minor changes in log file verbosity

Released 2014-08-13.

1.0.6

  • workaround for "ambiguous contract" issues for some particular IB symbols (MSFT, ...)
  • fix for stock symbols like XXX.Y (RDS.A for instance)
  • some other small changes/fixes
  • more verbose logging of slot allocation process

Released 2014-03-19.

1.0.5

  • fixed a bug causing "wait for min profit" engine status indicated outside trading hours

Released 2013-11-07.

1.0.4

  • z-score and profit potential now update also outside user's configured trading window (as long historical data were available)
  • manually opening/closing positions is now enabled in more engine states (for instance in "wait for min profit")
  • modified profit estimation formula for residual model, profit estimation now disabled for cases where A<0.1
  • fixed PDT protection in position exit logic
  • PTL Trader does not try to initialize trading engine and load historical data for portfolios bound to accounts not belonging to current IB account connected anymore
  • historical data are now downloaded and models are recalculated every day at 9:30 EST, so z-score and profit potential indicators work with updated model, instead of waiting for user's configured trading window

Internal release.

1.0.3

  • workaround for strategy P/L tracking (ignore portfolio data in IB "black hour" 0:** EST)
  • modified default log levels

First official stable release (2013-08-27).

1.0.2

  • workaround for equity tracking (ignore equity data in IB "black hour" 0:** EST)
  • more detailed logs for IB portfolio updates

Internal release.

1.0.1

  • debug logs for equity tracking
  • reworked execution and commission report handling (fixes slippage tracking problems and missing entries in transaction history)
  • PDT protection fix
  • libraries updated

Internal release.

1.0.0

  • changed valid range for instrument margins (15% - 100%)
  • cooldown period after closing a pair trade (it is not possible to open new pair trade earlier than in two minutes) - to prevent sending new orders until IB portfolio stats settle
  • more verbose logging of executions and commission reports (internal log)
  • reworked periodic premium membership checks
  • updated logo and icons

Internal release.

0.9.6b
