What's new in AmiBroker 5.50.5
Apr 9, 2012
- New Analysis window introduced in version 5.50 brings the following improvements over old Automatic Analysis
- multi-threaded operation = speed - new Analysis window uses all available CPUs/cores to execute formulas in many threads in parallel providing significant speed ups. For example on 4 core Intel i7 that can run upto 8 threads, it can run upto 8 times faster than old Analysis window. Exact speed up depends on complexity of the formula (the more complex it is, the more speedup is possible), amount of data processed (RAM access may be not as fast as CPU thus limiting possible speed gains)
- non-blocking operation - you can now view, scroll and sort results of analysis while they are still generated, also as user interface thread is not used for processing for most part, charts and other GUI-driven program parts are way more responsive than with old automatic analysis
- multiple instances - you can run more than one instance of New Analysis at a time, so you can run many scans/backtest/explorations/optimizations in parallel without waiting for one to complete
- slicker user interface - New Analysis window can act as tabbed document, can be floated, buttons can be re-arranged for better workflow. There is way more space for the result list, extra information about execution is provided on the new "Info" tab. Also walk-forward results are now displayed within New Analysis window for less clutter
- Mini High-Low rank chart in Real Time quote window
- User-definable mini bar charts in Explorations (see AddColumn function)
- Add Rank Column feature - right-click Analysis result list and choose "Add Rank column" - it adds a column with ordinal rankings based on current sort or just row number column when list is not sorted
- IRA account backtesting via SettlementDelay feature (see SetOption function)
- Range bars algorithm improved significantly
- new AFL functions: ThreadSleep, StaticVarCompareExchange
- updated AFL functions with new functionality: AddColumn, SetOption, GetOption, CategoryGetSymbols, PopupWindow, GetFnData, ClipboardSet
- updated OLE interface to support new Analysis window
- updated custom backtester interface to support access to local, per-analysis EquityArray property
- updated UI in many places
- Owner-draw list views for 10x speed improvement when displaying millions of rows
- many other improvements (see Release Notes for details)
