Released 2014-10-07.

1.1.0

• basic FA (Financial Adviser) account support (you have to enter the account code manually when connecting)

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.

• 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).

• reworked periodic premium membership checks
• updated logo and icons

Internal release.

• Status = BETA, not recommended for real trading yet (although we already use it that way ourselves)

Known issues we are working on

There are currently issues with installation under Java 1.8. You can get a message saying something like "Unable to find javaw.exe, searching...". The problem is that Java 1.8 no longer stores javaw.exe in a system path. The workaround is to edit PTL Trader icon (shortcut) properties and change the path to javaw.exe manually. Usually it resides in path like C:\Program Files\Java\jre1.8.0._25\bin\. We will fix this.
