FIXEdge 6.2.0 Release Notes

FIXEdge 6.2.0 released on June 23, 2017

New Features and Improvements

Latest FIX Antenna C++ under the hood:

MIFID II support:

  • Timestamps with increased precision can be validated in incoming messages (for UTCTimestamp, UTCTimeOnly, TZTimestamp, TZTimeOnly formats)
  • Timestamps in SendingTime (52), OrigSendingTime (122) are filled with configurable precision (per-session configurable property)
  • BL CopyField action has been enriched with methods intended to receive messages from the session with one timestamp precision and send to the session with another timestamp precision
  • JavaScript functionality has been extended with getNSecsetNSecchangeNSec to support high-precision timestamps

Please note that even though FIX Antenna C++ and FIXEdge support high precision timestamps the real accuracy of timestamps is limited by the operation system and hardware.

For more MIFID II compliance details see

Extension Packs:

RabbitMQ Transport Adapter 


  • The latest version of FIXICC 2.10.7 comes with the FIXEdge.


Critical bugs and fixes

  • FIXEdge cannot be started on Linux if directory name contains spaces 
  • FIXEdge cannot be started If two same sessions are listed in session list in config file
  • CME STP Transport Adaptor: FIX session can't connect to FIXEdge after several FIX session's simultaneous logout 
  • FIXEdge crashes if JavaScript functions are used incorrectly .
  • FIX dictionary for FIX 5.0, 5.0 SP1, 5.0 SP2: Tag CalculatedCcyLastQty (Tag = 1056) has incorrect requirement condition


Known issues

  • Log Replicator incorrectly synchronizes logs if their timestamps precision is higher than a millisecond.
  • CME STP Transport Adapter sends wrong LastUpdateTm value

FIXEdge 6.1.0 Release Notes

FIXEdge 6.1.0 released on March 31, 2017

New Features and Improvements

  • FIXEdge has been built with latest FIX Antenna C++ Release (2.18.1)
  • Environment variables can be used in and (not supported through FIXICC UI though)

  • RabbitMQ TA Consumer from group can't be created
  • CME STP adaptor falls into deadlock, causing FixEdge to stop accepting connections.
  • Logs are not deleted using FIXICC in Linux
  • Memory leak in In-Memory History
  • Memory corruption due to improper deinitialization of ODBC resources when working with ODBC History (postgresql specific)

Known issues

Since version 6.1.0 the JavaScript function getAsNumber works in another way in case the value can't be converted to a number. If previously it returned 0 if the whole string cannot be converted to a number, now it takes the substring till the first non-digit character and converts this substring. E.g. "20170321-05:00:00" is returned as 20170321 but not as 0 as it was in previous releases.
