Hello,
AmiBroker 5.27.0 ALPHA released
http://www.amibroker.com/devlog/2009/08/03/amibroker-5-27-0-alpha-released/
ALPHA means that this version is experimental and you *must* do backup of your data files before installing it. New version changes
the format of database files (quotation / stock / drawings ),
so once data are saved with version 5.27 you will NOT be able to read them in pre-5.27 version.
The ALPHA installer comes with simple backup program that will create a copy of your AmiBroker directory - it will display right
after new program files are copied. The backup will be created in C:\AmiBrokerBackup folder. Please note that this backup is
intended to copy the database files, not program files which will be overwritten anyway. If you want to backup program files too,
you need to backup them manually prior to installation. If you made your own backup prior to installation, you can skip (Cancel) the
backup part of the install routine.
CHANGES IN VERSION 5.27.0 (as compared to 5.26.0):
- changed core data structures to support the following
-- 64 bit date/time field with date range of 4095 years and resolution down to microseconds
-- floating point volume and open interest fields
-- two new auxilliary data fields per bar (internally, not yet exposed)
-- 100 new user-defined fundamental data fields (internally, not yet exposed)
-- support for GICS (internally, not yet exposed)
-- upto 48 character length in Symbol/Alias/WebID fields
- Updated plugins for eSignal, IQFeed, Interactive Brokers, Quotes Plus, Metastock to support floating point volume/open int and 64
bit date/time
- 1-second interval bars
- Metastock plugin now reads long symbol description
- Symbol lock fixed (does not interfere with Interval linking)
- Added simple "BackupAB.exe" to backup entire AmiBroker folder after installation to prevent data in old format.
