In general I agree its nice to have things fixed, there will always be
some so-called problem that needs fixing, depending on who you talk
too. I think its good to have a combination of fixing bugs and new
features which is exactly what is being done.
It also depends on HOW you use the program. If you are a visual
chart orientated trader all this so called "fluff and stuff", that is not
so important to you, may be very helpful.
Over the years there has been a huge amount of the more technical
features implemented within AmiBroker and some GUI work too, overall I think the
balance has been pretty good.

G> See CHANGE LOG below for detailed list of changes.
G> CHANGE LOG
G> CHANGES FOR VERSION 4.74.1 (as compared to 4.74.0)
G> Fixed incorrect message displayed in the progress window during some longer explorations
G> CHANGES FOR VERSION 4.74.0 (as compared to 4.73.0)
G> New user interface: fully user-customizable advanced docking panes/toolbars/menus.
G> New UI features:
G> Tear-Off Tabs Nested docking pane grouping WYSIWYG docking
G> sliding auto-hide pinnable windows modern "Whidbey" look Tear-Off
G> menus and toolbars Add/copy/Delete/Modify/drag-drop commands
G> User-defined toolbars
G> For a little video presentation see:
G> http://www.amibroker.com/video/uicustomize.htmlNote: toolbar and
G> keyboard customizations made in old versions need to be re-done
G> because they can not be imported by new system due to fundamental
G> differences (I am sorry about that)]
G> GroupID(), IndustryID(), SectorID, MarketID(), InWatchList(),
G> IsIndex() and IsContinuous() functions are now affected by
G> SetForeign
G> Removed debug messages cluttering DebugView output (that appeared in 4.73)
G> Changed the way drawing color picker is working: now it works
G> like in Word (or other text editor) - keeps selected color even if
G> drawing with different color is clicke
G> Fixed false message "The note has been modified outside the
G> notepad editor." occuring when file did not exist
G> OLE: Changed Window.LoadTemplate to return FALSE when file can not be found
G> OLE: Window.LoadTemplate now refreshes display so it is not
G> necessary to use SelectedTab = 0
G> Removed constant RT refreshes in interpretation window when text does not change
G> ZoomToRange: last selected bar in range is visible after zooming now
G> CHANGES FOR VERSION 4.73.0 (as compared to 4.72.1)
G> OLE: Window object, new method ZoomToRange( From, To )
G> ZoomToRange( From, To )
G> From and To parameters are of any type that can be converted to
G> date(you can use string or OLE date for example).
G> Example code (JScript):
G> AB=new ActiveXObject("Broker.Application");
G> AW = AB.ActiveWindow;
G> if( AW.ZoomToRange( "2005-04-01", "2005-08-01" ) )
G> {
G> WScript.Echo("Zoom successfull" );
G> }
G> Fixed: Chart got shrinked a bit with each overlaid plot, now
G> the Y scale does not change (unless really needed)
G> Fixed: XShift now works correctly with styleOwnScale and styleLeftScale
G> Fixed: Volume chart overlaid on price chart in log scale
G> (overlay) was compressed to flat line, now it is fixed (volume
G> chart overlay uses linear scale always)
G> [#22262]
G> AFL: Added AlmostEqual function (completed: 2005-09-16)
G> AlmostEqual( x, y, ulps = 5 )
G> this is a helper function for comparing floating point
G> numbers.It returns True if x and y are equal or almost equal upto
G> defined accurracy (ulps).It is recommended to use this function
G> instead of equality check (==) as itleads to more reliable
G> comparisons and less headache caused by IEEE floating pointacurracy
G> issues.
G> Parameters:x, y - the numbers or arrays to be compared,Ulps
G> stands for "units in last place" and represents maximum relative
G> error of the comparison. Since 32 bit IEEE floating point numbers
G> have accurracy of 7 significant digits, 1 unit in last place(ulp)
G> represents relative error of 0.00001 %. The default value of ulps
G> parameter is 5 which gives roughtly 0.00005% "comparison
G> sensitivity".
G> Example code:
G> if( 1/3 == 0.3333333 )
G> {
G> printf("32-bit Floating point IEEE exact equality\n");
G> }
G> if( AlmostEqual( 1/3, 0.3333333 ) )
G> {
G> printf("Numbers are almost equal\n");
G> }
G> Thanks to Bruce Dawson for his fast routine.
G> Optimize() function now checks if min < max, step > 0 and
G> checks if parameter name is not empty
G> Made Time&Sales case insensitive (when "case sensitive tickers" option is turned off")
G> OBV/AccDist/Chaikin functions adjusted to be SetForeign-aware
G> OLE: Application object new methods
G> BOOL LoadLayout( filename )
G> BOOL SaveLayout( filename )
G> AB = new ActiveXObject("Broker.Application");
G> AB.LoadLayout("C:\\Program
G> Files\\AmiBroker\\Data\\Layouts\\Default.awl");
G> OLE: Window object new property: SelectedTab
G> AB = new ActiveXObject("Broker.Application");
G> AW = AB.ActiveWindow;
G> tabindex = AW.SelectedTab; // read selected tab
G> AW.SelectedTab = 3; //switch to tab 3
G> AW.SelectedTab = tabindex; // restore originally selected tab
G> Fixed: Exception was generated when GetRTDataForeign was called with non-existing ticker
G> OLE: Window object new methods: LoadTemplate, SaveTemplate
G> AB = new ActiveXObject("Broker.Application");
G> AW = AB.ActiveWindow;
G> AW.SaveTemplate("Test.abt");
G> AW.LoadTemplate("Test.abt ");
G> CHANGES FOR VERSION 4.72.1 (as compared to 4.72.0)
G> fixed out-of-memory problem sometimes occuring during scan of large (>512MB) databases
G> CHANGES FOR VERSION 4.72.0 (as compared to 4.71.1)
G> " Currency" field support in ASCII importer
G> added command:
G> $CURRENCY USD
G> and field:
G> $FORMAT Name,Currency$OVERWRITE 1$AUTOADD 1]
G> Added "Additional commands" field in the Import wizard for
G> typing any extra $- commands that are not available via checkboxes
G> Added parameter to AddColumn/AddTextColumn to control column width
G> AddColumn( ARRAY, "Caption", format = 1.2, color =
G> colorDefault, bgcolor = colorDefault, width = -1);
G> AddTextColumn( "Text", "Caption", format = 1.2, color =
G> colorDefault, bgcolor = colorDefault, width = -1 );
G> AddToComposte new flag to work when Status("action")==
G> actionPortfolio (completed: 2005-09-09)
G> new flag is called atcEnableInPortfolio
G> Example:
G> if( Status("action" ) == actionPortfolio )
G> {
G> ... Custom backtest mode here ....
G> AddToComposite( some_array, "~COMPOSITE", "X",
G> atcFlagEnableInPortfolio | atcFlagDefaults );
G> }
G> AFL added: tanh(), sinh(), cosh() functions
G> Hyperbolic tangent, sine and cosine function
G> AFL functions: StrToUpper and StrToLower
G> Fixed: Tick ASCII import: last tick of previous import was
G> deleted on subsequent import, now it is corrected
G> Function to detect mouse button state
G> GetCursorMouseButtons() returns mouse button state at the time when chart formula is executed
G> 0 - if no mouse button is pressed
G> 1 - if left mouse button is pressed
G> 2 - if right mouse button is pressed
G> 4 - if middle mouse button is pressed
G> plus combinations:3 - left + right5 - left + middle6 - right +
G> middle 7 - left + right + middle]
G> GetRTDataForeign (retrieving values for other symbols)
G> GetRTDataForeign( "field", "symbol")
G> Pane is not deleted if shrinked down to zero (prevents from accidential deletion of panes)
G> Plot function now has xshift parameter that allows to visually
G> shift the chart past the last bar
G> Example 20-bar Moving average shifted 10 bars into the future past the last bar:
G> Plot(Close,"Close",colorBlack,styleCandle);Plot(MA(Close,20),
G> "Shifted MA", colorRed, styleLine, Null, Null, 10 );
G> Note that shift occurs during plotting and does not affect source array
G> Removed data source selection from preferences because it
G> caused user confusion way too often
G> Stock.Currency available via OLE
G> Title variable now supports new special token {{OHLCX}} which
G> is replaced at runtime by string "Open ..., Hi .... Lo ... Close
G> (...%)" showing current price
G> This way it is possible to implement formula that will show
G> OHLC prices with number of decimal places set in the preferences.
G> Example:
G> SetChartOptions(0,chartShowArrows|chartShowDates);
G> _N(Title = "{{NAME}} - {{INTERVAL}} {{DATE}} {{OHLCX}} {{VALUES}}" );
G> Plot( C, "Close", ParamColor("Color", colorBlack ),
G> styleNoTitle | ParamStyle("Style") | GetPriceStyle() );
G> user-definable number of decimal places in chart titles (completed: 2005-09-09)
G> Number of decimal places displayed in default chart title is
G> now user-definable inTools->Preferences->Miscellaneous"Decimal
G> places in chart titles".
G> Allowable values:
G> -1 - dynamic mode (number of decimal places automatically adjusted)
G> 0..6 - fixed number of decimal places
G> QuoteArray resizing now uses heuristic algorithm to minimize
G> memory fragmentation and increase performance
G> atcFlagDeleteValues now highlighted properly in the AFL editor
G> CHANGES FOR VERSION 4.71.1 (as compared to 4.71.0)
G> fixed compatibility problem with AmiQuote (due to changed order
G> of OLE properties/method while AmiQuote was using old ones) now
G> ASCII importer in $TICKMODE does not delete quotes older than
G> oldest (first) record in the imported file, so you can safely
G> import tick data from subsequent files (older first, newest later)
G> CHANGES FOR VERSION 4.71.0 (as compared to 4.70.5)
G> AFL: added GetCursorXPosition() and GetCursorYPosition() functions
G> Functions return current mouse cursor position.
G> Values returned are equal to those visible in the status bar,
G> and these functions require status bar to be visible. Returned
G> values represent cursor position at the formula execution time (or
G> few milliseconds before it) and accurracy is subject to pixel
G> resolution of the screen (first cursor position is read in screen
G> pixels (integer) and then converted to actual value therefore for
G> example when screen resolution is 1024x768 maximum obtainable
G> resolution in X direction is 0.1% and in Y direction 0.13%), also
G> X values are snap to datetime of nearest data bar.
G> It only makes sense to use these functions in indicator/interpretation code.
G> Using them in AA window may yield random
G> values.GetCursorXPosition() function returns X position in DateTime
G> format (the same as used by DateTime() function).You can convert it
G> to string using DateTimeToStr() function.GetCursorYPosition()
G> returns Y position (as displayed in Y axis of the chart).
G> Example:
G> ToolTip="X="+DateTimeToStr(GetCursorXPosition()) +"\nY="+GetCursorYPosition();
G> AFL: added DateTimeToStr() and StrToDateTime() functions
G> These functions allow to convert string to datetime format and vice versa.
G> Example:
G> ToolTip="X="+DateTimeToStr(GetCursorXPosition()) +"\nY="+GetCursorYPosition();]
G> Added ability to store charts as .GIF (in addition to PNG)
G> ASCII importer maximum supported line length is increased to 2048 characters
G> Fixed: .aflsafe files didn't get deleted automatically
G> Added N-volume bars charts and timeframe support.
G> Custom N-volume bar intervals are definable (as usual) in Tools->Preferences->Intraday.
G> TimeFrame functions were also extended to support N-volume bars
G> using new TimeFrameMode() function calling
G> TimeFrameMode( 0 );
G> - switches time frame functions to time-based operation (the default)
G> TimeFrameMode( 1 );
G> - switches time frame functions to N-tick operation (positive
G> values passed to TimeFrameSet are treated now as N-tick)
G> TimeFrameMode( 2 );
G> - switches time frame functions to N-volume bar operation
G> (positive values passed to TimeFrameSet are treated nowas N-volme
G> bars)
G> Example:
G> TimeFrameMode( 2 );
G> TimeFrameSet( 50000 ); // 50'000 share bars..
G> ...do something ...
G> TimeFrameRestore();
G> Note: N-volume bars are somewhat weird (compression of data to
G> N-volume bar may actually deliver MORE output bars - for example if
G> one tick is 1000 shares and you have specified 100V bars then
G> single tick will be expanded to TEN 100V bars - ten times original
G> size)
G> TimeFrame functions are protected against array overrun and
G> will not decompress beyond original array size (you will get an
G> "Error 47. N-volume bar compressed data longer than base time
G> frame").
G> Also switching main time frame to some weird N-volume bar value
G> will result in limiting the output to maximum twice original data
G> size(without error message).
G> You should keep that in mind and avoid using too small N-volume
G> bar intervals that could lead to such condition.
G> Also due to the nature of N-volume bars the only TimeFrameSet()
G> function will yield correct N-volume bar values,
G> TimeFrameGetPrice() may give slightly distorted results.
G> It is also possible to use n-volume bars in TimeFrame functions
G> without calling TimeFrameMode() - it is then necessary to specify
G> n-volume bars as negative number offset by -1000000 (minus one
G> million):
G> TimeFrameSet( -1000000 - 2000 );
G> // gives 2000V barsSimilarly formatted negative numbers will be
G> reported by Interval() function when n-volume bars are selected.
G>
G> OLE: Save As PNG / GIF callable from automation
G> Example script:
G> AB = new ActiveXObject("Broker.Application");
G> AB.ActiveWindow.ExportImage("Test.png");
G> Plugin is not called when GetExtraData is used for symbol that
G> has "use only local database" flag turned on, and NULL is returned
G> instead of an error
G> Protected against changing application's current working directory by printing to file
G> Toolbar does not get wrapped when main frame window is resized
G> OLE: Analysis object has new method MoveWindow( x, y, width,
G> height) that allows to control position and size of automatic
G> analysis window
G> AB = new ActiveXObject("Broker.Application");
G> AB.Analysis.MoveWindow ( 10, 10, 200, 200 );
G> It has some restrictions on size: specified size can not
G> besmaller than 10x10 pixels and can not be bigger than entire
G> screen dimensions.
G> Also when "No minimum size for resizing dialogs" box in
G> UNCHECKED in Tools->Prefs->Misc it won't shink AA window below
G> default size necessary to fully display all controls.
G> ASCII importer: added ability to import tick data from text files
G> ASCII importer now allows tick data files to be imported.
G> Tick data files consist of several records having the same
G> timestamp.This makes it impossible to use normal import mode which
G> assumes different (unique) timestampsfor each data row (when same
G> timestamp is found then new data overwrites old).
G> To turn on TICK mode you need to add manually
G> $TICKMODE 1
G> line to ASCII importer definition file.
G> $TICKMODE is a special mode of importer that allows to import
G> quotes that haveduplicate time stamps.
G> It makes two assumptions:
G> a) input data should come in the ascending time order (i.e.
G> OLDER records first, LATEST records last)
G> b) input data should consist of entire tick history because
G> importer will DELETE any existing quotes (to avoid creating
G> multiple copies of the same ticks).
G> Once again: Turning on
G> $TICKMODE 1
G> will DELETE ANY QUOTES that already exist in the database and
G> then will import all ticks from input data file.
G> You have been warned.
G> For example data files like this:
G> MOL,0,20050606,162959,16400.0000,16400.0000,16400.0000,16400.0000,2MOL,0,20050606,162959,16400.0000,16400.0000,16400.0000,16400.0000,11MOL,0,20050606,162959,16400.0000,16400.0000,16400.0000,16400.0000,40
G> Can be imported using the following definition file:
G> $FORMAT Ticker, Skip, Date_YMD, Time, Open, High, Low, Close, Volume
G> $SKIPLINES 1
G> $SEPARATOR ,
G> $CONT 1
G> $GROUP 255
G> $AUTOADD 1
G> $DEBUG 1
G> $TICKMODE 1
G> Sometimes it happens that input files have invalid timestamps (seconds > 59).
G> For example:
G> MOL,0,20050606,162970,16400.0000,16400.0000,16400.0000,16400.0000,2
G> Please take a closer look at first line shown in this example
G> it has time:16:29:70 (you see 70 seconds !)
G> So I had to add a special flag to the importer that works around such data errors.
G> It is called $ALLOW99SECONDS 1 and will convert all records
G> with invalid seconds (i.e greater than 59)to 59s.
G> So record stamped 16:29:70 will be treated as 16:29:59
G> Now for tick mode to work with such incorrect records you would
G> need to add two lines to ASCII importer definition:
G> $TICKMODE 1
G> $ALLOW99SECONDS 1
