>
> 2.. During first run you will see the note "Due to a software update the
>toolbar 'View' has changed. Would you like to reset your customized toolbar
>and load the new one?". It is normal and won't appear any more than once.
>If you answer Yes then View toolbar will be reset to default, if you answer

> to have the key sent to you.
>
> 4.. If you are using Firewall you may need to check if it did not block
>Broker.EXE file after upgrade. (It happened to some users that firewall
>blocked AmiBroker after upgrade and they could not connect to RT data

> [#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
