Hello,
A new beta version (5.01.0) of AmiBroker (code name "SPEED BOOST")
has just been released.
http://www.amibroker.com/devlog/2007/10/04/amibroker-5010-beta-released/
The code name for this release is "SPEED BOOST" as it brings 2x speed
increase for backtest and optimizations. This is the result of
many days of code profiling and tweaks. The result is achieving dual-core
performance on old computers (no hardware update
necessary)
Portfolio backtester on average 2x faster for both multiple and single-security
tests (some trivial, frequently trading systems may
observe upto 5x speedup on multiple securities during long analysis periods).
Note that AFL engine speed has NOT changed as compared
to 5.00. Speed increase comes from backtester tweaks alone, so the longer AFL
code is the less speed-up you will see, because
backtester processing would account for smaller part of overall execution time.
There is also new Code Profiler available from AFL Editor, Tools->Code Check
& Profile, that shows detailed report on how many times
each function is called and how much time it takes to execute.
Best regards,
Tomasz Janeczko
