Another small glitch I'm having is that in the AFL editor I cannot put the
"file - edit - tools -help" toolbar on the same line as the standard
toolbar.

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