Greetings Tomasz,
An easy newbie question. I have Amibroker installed on my D drive under the
Aminbroker folder. Do I extract the file to my D drive or under the
Amibroker folder.
I actually tried both and the version has not changed from 4.29 beta.
I'm sure that I goofed up. Pls advise.
Regards,
Bruce

>AmiBroker 4.29.9 Beta Read Me
>March 7, 2003 20:47
>
>THIS IS A BETA VERSION OF THE SOFTWARE. EXPECT BUGS.
>
>Backup your data files and entire AmiBroker folder first!
>
>INSTALLATION INSTRUCTIONS
>
>IMPORTANT: This archive is update-only. You have to install full version
>4.20 first.
>
>Just run the installer and follow the instructions.
>
>Then run AmiBroker. You should see "AmiBroker 4.29.9 beta" written in the
>About box.
>
>CHANGES FOR VERSION 4.29.9 (as compared to 4.29.8)
>
> a.. added key shortcuts for range mark begin (F12), end (Shift+F12),
>hide (Ctrl+F12) (they are also available in Keyboard editor so assignments
>can be changed)
> b.. chart scroll left/right are now accessible from keyboard editor
>(ChartScrollLeft, ChartScrollRight)
> c.. if type-in is selected from the main menu then watch list selector
>dialog is displayed.
> d.. fixed sometimes wrong sort when many explorations were run one after
>another with some non-numeric columns.
> e.. Study() works correctly even when trendline is drawn past the last
>available data bar.
>
>CHANGES FOR VERSION 4.29.8 (as compared to 4.29.7)
>
> a.. updated param info for LastValue, MarketID, GroupID, SectorID,
>IndustryID to match the AFL reference
> b.. decreased delay time for baloon tooltip (status bar area)
> c.. fixed hang of Windows XP when AmiBroker tried to display the tooltip
>while AB was minimized. (cause of crash of WinXP when QT was closed before
>AB)
> d.. infinite numbers are printed now as {INF}, not-a-numbers are printed
>as {NAN} by WriteVal.
> For example:
> "1/0 =" + WriteVal((1/0));
> "0/0 =" + WriteVal(0/0);
> "(1/0) / (1/0) =" + WriteVal((1/0)/(1/0));
> "1 / (1/0) =" + WriteVal( 1 / ( 1 / 0 ) );
> "Null =" +WriteVal(Null);
> e.. 3 new AFL functions:
> a) IsNan( x ) - returns a nonzero value (1 or TRUE) if the argument x is
>a NaN; otherwise it returns 0 (FALSE).
> A NaN is generated when the result of a floating-point operation cannot
>be represented in Institute of Electrical and Electronics Engineers (IEEE)
>format
>
> Example:
> IsNan( 0/0 );
>
> b) IsFinite( x ) - IsFinite returns a nonzero value (1 or TRUE) if its
>argument x is not infinite,
> that is, if -INF < x < +INF. It returns 0 (FALSE) if the argument is
>infinite or a NaN.
>
> Example:
> IsFinite( 1/0 );
>
> c) Nz( x ) - Null (Null/Nan/Infinity) to zero
>
> You can use the Nz function to return zero, or another specified value
>when argument x is Null or Nan or Infinite.
> For example, you can use this function to convert a Null (empty) value
>to another value and prevent it from propagating through an expression. If
>the optional valueifnull argument is included,
> then the Nz function will return the value specified by that argument if
>the x argument is Null (or Nan or Infinity).
>
> You can use the Nz function as an alternative to the IIf function.
>
> Instead of:
> varTemp = IIf( IsFinite( (H-L)/(C-L) ), (H-L)/(C-L), 0 );
>
> You can write:
> varTemp = Nz( (H-L)/(C-L) );
>
>
> f.. added IsNull() function - it is the synonym to IsEmpty()
>
>CHANGES FOR VERSION 4.29.7 (as compared to 4.29.6)
>
> a.. added "ask to save changed data" option to Prefs->Misc page (if it
>is unchecked AmiBroker saves data without asking)
> b.. Symbol -> WatchList ->Import now accepts all formats of .LST files
>from Quotes Plus
> c.. fixed crash when backward ref bar number was too high
> d.. date axis drawing modified (should address 'missing oct 2001'
>problem)
> e.. fixed crash when using extreme zoom in factors (via Zoom to range)
>and scrolling max to the right so only blank area is visible.
> f.. added check for neg. # of contracts
> g.. Apply in Indicator Builder does not scroll to the top
> h.. other minor fixes:
>
>CHANGES FOR VERSION 4.29.6 (as compared to 4.29.5)
>
> a.. WriteVal has now new parameter 'separator' that controls if the
>number
> should be formatted with thousand separator or not:
>
> WriteVal( ARRAY, format = 8.3, separator = True )
>
> WriteVal( Volume, 8.3, True ); // with separators
> WriteVal( Volume, 8.3, False ); // without separators
>
>
> b.. thousand separator is not added to numbers in AA->Export
> c.. thousand separator does not appear when using
> AddColumn( DateTime(), formatDateTime );
> d.. fixed inconsistency between AA result line (incorrect) and AA report
>(correct) when formula was using
> SetOption("InitialEquity", nn) to change the Init. equity set in the AA
>settings
> (thanks Herman)
> e.. fix: % change is displayed again in RT quote window.
> f.. fix: watch list dialog (watch list->remove) does not show lists
>above > 32 if given symbol does not belong to given watch list.
> g.. new AFL function: GetChartID() allows to retrieve current indicator
>chart ID. (returns 0 (zero) in AA window)
> h.. other minor fixes
>
>CHANGES FOR VERSION 4.29.5 (as compared to 4.29.1)
>
> a.. fixed crash in AFL editor that occured when selecting all text and
>choosing right mouse button -> copy
> b.. auto-scaling changed slightly
> c.. user-definable thousand separator (in Tools->Preferences->Misc)
>applied automatically to all list views and indicators and WriteVal
>function
> d.. definable number of decimal places in RT quote window
>(Tools->Prefs->Misc)
> e.. watch-list related functions: (available from context menu in tree
>and Symbol->Watch list menu)
> f.. quick type-in symbols into watch list
> g.. import/export watch list from/to .LST file and from/to plugin (ext.
>database only for plugins that support this feature. The first one will be
>FT plugin)
> h.. context menu is displayed over selected watch list (click with right
>mouse button on the watch list name in the Workspace window)
> i.. 'dirty' flag is set properly after moving/sizing the study
> j.. Amibroker again displays message box asking to save changes. (this
>is useful to undo some unwanted changes but it works only for most recent
>'in-memory' symbols (see Tools->Preferernces->Data))
> k.. fixed the case when Preferences has log scale switched OFF but
>Indicator Builder has "log scale" turned ON for Price chart.
>CHANGES FOR VERSION 4.29.1 (as compared to 4.29.0)
>
> a.. data tooltips now show study ID and coordinates and point/percent
>change from start to end when you hover the mouse pointer over the trend
>line or other study
> b.. from-to range selector implemented just double click on chart to
>mark begin and then double click in other place to mark end of the range. >
>and < markers will appear above date axis. To delete the markers double
>click again in the same place where vertical line is positioned.
> c.. From-to selected range can be referred from the AFL level via new
>functions
> BeginValue( ARRAY )
> EndValue( ARRAY )
> - these functions give the single value (number) of the ARRAY at the
>beginning and end of the selected range. If no range is marked then they
>return the value at the first bar and last bar respectively.
>
> Example:
>
> WriteVal( BeginValue( DateTime() ), formatDateTime );
> WriteVal( EndValue( DateTime() ), formatDateTime );
> "Precentage change of close is " +
> WriteVal( 100 * (EndValue( Close ) - BeginValue( Close ))/BeginValue(
>Close ) ) + "%";
>
>
> d.. WriteVal function now handles formatDateTime
> WriteVal( DateTime(), formatDateTime );
>
>
> e.. Zoom to range implemented (View->Zoom->Range) or hold down both
>SHIFT and CTRL and click on green zoom in toolbar button (zooms to selected
>from-to range)
>
>CHANGES FOR VERSION 4.29.0 (as compared to 4.28.1)
>
> a.. context help in AFL editor - just press F1 when cursor is over AFL
>reserved function name and it will display full information about that
>function
> b.. param info/fun reference available also from context menu
> c.. fixed bug in Study function working improperly for trendlines with
>right extend property
> d.. tab order fixed in Study properties box
> e.. usability: "Filter pre/after hours" is available now from
>View->Intraday menu
> f.. new AFL function:
> Now( format = 0 ) returns current date / time in numerous of formats:
> format = 0 - returns string containing current date/time formatted
>according to system settings
> format = 1 - returns string containing current date only formatted
>according to system settings
> format = 2 - returns string containing current time only formatted
>according to system settings
> format = 3 - returns DATENUM number with current date
> format = 4 - returns TIMENUM number with current time
> format = 5 - returns DATETIME number with current date/time
> See: http://www.amibroker.com/guide/afl/afl_view.php?name=NOW
> g.. new drawing tool: Triangle
> h.. new drawing tool: Andrews' Pitchfork
> i.. Gann Square tool does not draw controlling trenline during
>move/resize
> j.. added check that prevents freeing memory by Equity(1) function when
>this memory is referenced by other variables
> k.. added Layer combo to the Text properties box
> l.. added link to AFL on-line reference to the Help->AmiBroker on the
>Web menu.
> m.. switching layers does not cause unnecessary symbol tree refresh
> n.. added switch to AA Settings->Report tab that allows to turn off
>optimization warning (that is displayed if optimization requires more than
>300 steps)
> o.. other minor fixes.
>
>CHANGES FOR VERSION 4.28.1 (as compared to 4.28.0)
>
> a.. fixed problem with missing some short trades when new flag "Reverse
>entry signal forces exit" was turned off
> b.. Null is now highlighted and present in the auto-complete box.
> c.. fixed numeric sorting of colorized columns
>CHANGES FOR VERSION 4.28.0 (as compared to 4.27.1)
>
> a.. ApplyStop has one more parameter
> ApplyStop( Type, Mode, Amount, ExitAtStop, Volatile = False )
>
> new Volatile parameters decides if amount (or distance) (3rd parameter)
>is sampled at the trade entry and remains fixed during the trade (Volatile
>= FALSE - old behaviour) or if can vary during the trade (Volatile = TRUE)
>
> Allows single-line implementation of Chandeliers exit:
>
> ApplyStop(stopTypeTrailing, stopModePoint, 3*ATR(14), True, True );
>
>
> b.. ApplyStop handles new N-Bar stop - exits the trade after N bars.
> Type = stopTypeNBar; /* = 3 */
> Mode = stopModeBars; /* = 1 */
>
> ApplyStop( stopTypeNBar, stopModeBars, 5 ); // exits trades on 5th bar
>since entry
>
>
> c.. added new "Reverse entry signal forces exit" check box to the
>Backtester settings.
> When it is ON (the default setting) - backtester works as in previous
>versions and closes already open positon if new entry signal in reverse
>direction is encountered. If this switch is OFF - even if reverse signal
>occurs backtester maintains currently open trade and does not close positon
>until regular exit (sell or cover) signal is generated.
> In other words when this switch is OFF backtester ignores Short signals
>during long trades and ignores Buy signals during short trades.
>
>
> d.. added "Allow same bar exit (single bar trade)" option to the
>Settings
> When it is ON (the default settings) - entry and exit at the very same
>bar is allowed (as in previous versions)
> if it is OFF - exit can happen starting from next bar only (this applies
>to regular signals,there is a separate setting for ApplyStop-generated
>exits). Switching it to OFF allows to reproduce the behaviour of MS
>backtester that is not able to handle same day exits.
>
>
> e.. long trades now take precedence over short trades so if signals
>happen on the same bar in both directions only long trade is taken.
>
>
> f.. new AFL functions:
> DateTime() - returns array of encoded date/time values suitable for
>using with
> AddColumn and formatDateTime constant
> to produce date time formated according to your system settings
>
> AddColumn( DateTime(), "Date / Time", formatDateTime );
>
> new formatChar constant allows outputting single ASCII character codes:
>
> Example (produces signal file accepted by various other programs):
>
> Buy=Cross(MACD(),Signal());
> Sell=Cross(Signal(), MACD());
> Filter=Buy OR Sell;
> SetOption("NoDefaultColumns", True );
> AddColumn( DateTime(), "Date", formatDateTime );
> AddColumn( IIf( Buy, 66, 83 ), "Signal", formatChar );
>
>
> g.. new AFL functions continued:
> BarIndex() - returns zero-based bar number -
> the same as Cum(1)-1 but it is much faster than Cum(1) when used in
>Indicators
>
> SetOption( "name", value )
> - sets various options in automatic analysis settings currently
>available options are
> "NoDefaultColumns" - if set to True - exploration does not have default
>Ticker and Date/Time columns
> "InitialEquity"
> "AllowSameBarExit"
> "ActivateStopsImmediately"
> "AllowPositionShrinking"
> "FuturesMode"
> "InterestRate"
>
>
> h.. if you overwrite AA settings via SetTradeDelays/SetOption
> backtest report gives these actual values instead of originaly set in
>the settings
>
>
> i.. new Null constant is equal to -1e10 (empty value) so you can use it
>instead enigmatic -1e10
>
> obsolete styleLog removed (logarithmic scale setting is not per-line but
>per-pane and it is selectable from Indicator Builder)
>
>
> j.. added PlotGrid( level, color = colorDefault ) function that plots
>grid line using built-in dotted style.
>
>
> k.. fixed problem with QuoteEditor that was introduced with adding color
>support to the list view
> l.. added support for Win XP common controls 6, which results in
>enhanced XP-look (on WinXP only of course)
> m.. fixed zero-size problem with floating control bars on Windows XP
> n.. fixed some compatibility issues with common controls 6.
> o.. added sound when plugin status changes
> p.. fixed problems with Review window sometimes not showing the results
> q.. value label drawing changed slightly
> r.. status bar adjusted so plugin state is visible on smaller displays
> s.. improved windows version checking for bug reports
>
>CHANGES FOR VERSION 4.27.1 (as compared to 4.27.0)
>
> a.. fixed problems with auto-complete and param info features appearing
>on certain Windows versions
>CHANGES FOR VERSION 4.27.0 (as compared to 4.26.0)
>
> Intellisense-like functionality in AFL editor
>
> a.. auto-completion feature in AFL editor type a few letters and press
>Ctrl+SPACE and the number of matching functions / reserved words will be
>displayed
> b.. parameters-info tip, type function name and opening brace ( and you
>will see the tip that shows information about required parameters
> c.. two new checkboxes Preferences->Editor control Auto-completion /
>parameter-info features
> d.. fixed exception occuring when optimizing systems that generate zero
>trades (very rare case)
> e.. AlertIF called from the custom indicators sometimes displayed wrong
>date/time - now it is fixed
> f.. when fixup = 1 Foreign() is able to align array past the last
>foreign bar. For example when using intraday data you can refer to imported
>EOD data and it will fill intraday data with last value from previous day.

>CHANGES FOR VERSION 4.26.0 (as compared to 4.25.0)
>
> a.. List view sorting speed increased significantly:
> a.. sorting of text columns is 2 times faster (on average)
> b.. sorting of numeric column is 5-10 times faster ( sort 660'000
>items within 2-3 seconds on 1GHz machine)
> b.. Explorations now support definable color of cell text and background
> AddColumn and AddTextColumn functions extended to support this feature:
>
> AddColumn( Array, "Title", format = 1.2, textColor = colorDefault,
>bkgndColor = colorDefault );
> AddTextColumn( "Text", "Title", format = 1.2, textColor = colorDefault,
>bkgndColor = colorDefault );
>
> New colorDefault constant (-1) defines default windows color for grid
>cell.
> Sample code:
> Filter =1;
>
> AddColumn( Close, "Close", 1.2 );
> AddColumn( MACD(), "MACD", 1.4 , IIf( MACD() > 0, colorGreen, colorRed )
