other minor fixes:
CHANGES FOR VERSION
4.29.6 (as compared to 4.29.5)
WriteVal has now new
parameter 'separator' that controls if the numbershould be formatted with
thousand separator or not:WriteVal( ARRAY, format = 8.3,
separator = True )WriteVal( Volume, 8.3, True ); // with
separatorsWriteVal( Volume, 8.3, False ); // without separators
thousand separator is not added to numbers in AA->Export
thousand separator does not appear when usingAddColumn( DateTime(),
formatDateTime );
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)
fix: % change is displayed again in RT quote window.
fix: watch list dialog (watch list->remove) does not show lists above
> 32 if given symbol does not belong to given watch list.
new AFL function: GetChartID() allows to retrieve current indicator chart
ID. (returns 0 (zero) in AA window)
other minor fixes
CHANGES FOR VERSION
4.29.5 (as compared to 4.29.1)
fixed crash in AFL editor that occured when selecting all text and
choosing right mouse button -> copy
auto-scaling changed slightly
user-definable thousand separator (in Tools->Preferences->Misc)
applied automatically to all list views and indicators and WriteVal function
definable number of decimal places in RT quote window
(Tools->Prefs->Misc)
watch-list related functions: (available from context menu in tree and
Symbol->Watch list menu)
quick type-in symbols into watch list
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)
context menu is displayed over selected watch list (click with right mouse
button on the watch list name in the Workspace window)
'dirty' flag is set properly after moving/sizing the study
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))
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)
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
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.
From-to selected range can be referred from the AFL level via new
functionsBeginValue( 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 ) ) + "%";
WriteVal function now handles formatDateTimeWriteVal( DateTime(),
formatDateTime );
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

function
param info/fun reference available also from context menu
fixed bug in Study function working improperly for trendlines with right
extend property
tab order fixed in Study properties box
usability: "Filter pre/after hours" is available now from
View->Intraday menu
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 settingsformat = 1 - returns
string containing current date only formatted according to system
settingsformat = 2 - returns string containing current time only formatted
according to system settingsformat = 3 - returns DATENUM number with
current dateformat = 4 - returns TIMENUM number with current

steps)
other minor fixes.
CHANGES FOR VERSION
4.28.1 (as compared to 4.28.0)
fixed problem with missing some short trades when new flag "Reverse entry
signal forces exit" was turned off
Null is now highlighted and present in the auto-complete box.
fixed numeric sorting of colorized columns
CHANGES FOR VERSION
4.28.0 (as compared to 4.27.1)
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 );
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
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.
added "Allow same bar exit (single bar trade)" option to the
SettingsWhen 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.
long trades now take precedence over short trades so if signals happen on
the same bar in both directions only long trade is taken.
new AFL functions:DateTime() - returns array of encoded date/time
values suitable for using withAddColumn and formatDateTime constantto
produce date time formated according to your system
settingsAddColumn( 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 );
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"
if you overwrite AA settings via SetTradeDelays/SetOption backtest
report gives these actual values instead of originaly set in the
settings
new Null constant is equal to -1e10 (empty value) so you can use it
instead enigmatic -1e10obsolete styleLog removed (logarithmic scale
setting is not per-line but per-pane and it is selectable from Indicator
Builder)
added PlotGrid( level, color = colorDefault ) function that plots grid
line using built-in dotted style.
fixed problem with QuoteEditor that was introduced with adding color
support to the list view
added support for Win XP common controls 6, which results in enhanced
XP-look (on WinXP only of course)
fixed zero-size problem with floating control bars on Windows XP
fixed some compatibility issues with common controls 6.
added sound when plugin status changes
fixed problems with Review window sometimes not showing the results
value label drawing changed slightly
status bar adjusted so plugin state is visible on smaller displays
improved windows version checking for bug reports
CHANGES FOR VERSION
4.27.1 (as compared to 4.27.0)
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
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
parameters-info tip, type function name and opening brace ( and you will
see the tip that shows information about required parameters
two new checkboxes Preferences->Editor control Auto-completion /
parameter-info features
fixed exception occuring when optimizing systems that generate zero trades
(very rare case)
AlertIF called from the custom indicators sometimes displayed wrong
date/time - now it is fixed
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)
List view sorting speed increased significantly:
sorting of text columns is 2 times faster (on average)
sorting of numeric column is 5-10 times faster ( sort 660'000 items
within 2-3 seconds on 1GHz machine)
Explorations now support definable color of cell text and
backgroundAddColumn 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 ) );AddTextColumn( FullName(),
"Full name", 77 , colorDefault, IIf( Close < 10, colorLightBlue,
colorDefault ) );
custom indicators - anchors are not offset vertically from the ends of the
trend line when Draw dates is selected
custom indicators with auto-scaling can be now dragged in Y-direction like
regular charts
Foreign and RelStrength algorithm improved to allow more complex alignment
cases
PlotShapes works even without any Plot statement (although it is intended
to use in conjunction with Plot)
fixed line disappearing bug that occured when using text tool right after
trend line tool
Dec is displayed again on date axis
CHANGES FOR VERSION
4.25.0 (as compared to 4.24.0)
support user-definable parameters:new AFL functionsParam( "name",
default, min, max, step )ParamStr( "name", "default" );ParamColor(
"name", defaultcolor );new Parameters dialog : right click over chart
pane and select "Parameters" or press Ctrl+Rallows to change chart
parameters - changes are reflected immediatelly
Sample code 1:ticker = ParamStr( "Ticker", "MSFT"
);sp = Param( "MA Period", 12, 2, 100 );PlotForeign( ticker, "Chart of
"+ticker, ParamColor( "Price Color", colorLightYellow ), styleCandle
);Plot( MA( Foreign( ticker, "C" ), sp ), "MA(" + WriteVal( sp, 1.0 ) +
")", ParamColor( "MA Color", colorRed ) );
Sample code 2:sp = Param( "RSI Period", 12, 2, 100
);r = RSI( sp );Plot( r, "RSI("+WriteVal(sp,1.0)+")", ParamColor("RSI
Color", colorRed ) );
Buy = Cross( r, 30 );Sell = Cross( 70, r );
PlotShapes( shapeUpArrow * Buy + shapeDownArrow * Sell, IIf( Buy,
colorGreen, colorRed ) );
added missing ':' and '"' characters to the forbidden characters set in
file names generated from ticker names. All file-system reserved characters
are converted to underscore.
ticker symbol maximum length increased to 25 characters (from previous
15).(these two fixes above solve problem with using very long symbols like
default keyboard accelerators changed Ctrl+R is now for Parameters dialog
F5 is for Refresh
fixed calculation bug occuring when drawing objects in the blank chart
area ("jumping" effect)
new method in Quotations collection for faster retrieval of quoteslong
Retrieve( long Count, Variant *Date, Variant *Open, Variant *High, Variant
*Low, Variant *Close, Variant *Volume, Variant *OpenInt );
on Windows Me, 2000 and XP all file dialogs now feature "Places" bar and
allows to select few recent file names from the combo
date axis display modified slightly (3 letter month abbrev. used more
often
changed resizing algorithm so if "no min size for resizing dialog" option
is selected the scroll bar of list / edit is always visible. Also the option
is active from the start without need to go to Preferences.
other minor improvements

CHANGES FOR VERSION
4.23.0 (as compared to 4.22.1)
chart axis font can be defined by the user. The default is now Arial,
9pt.(Tools->Preferences->Miscellaneous: "Axis font")
Undo feature added to AFL editor.
PlotShapes now supports offset (or distance) parameter (by default -12 ),
Offset is expressed in SCREEN pixels.Negative offsets shift symbols down,
positive offsets shift symbol up. To place the shape exactly at ypostion,
specify 0 as offset. PlotShapes( shape, color, layer = 0, yposition =
graph0, offset = -12 );
yet another bug fixed that caused problems with drawing lines when
multiple windows were showing same symbol but different intervals.
if Y-value is less than 1000 the status bar displays four decimal places ,
also bar number is displayed in the status bar (next to date/time)
Insert Indicator window (Ctrl+I) does not show empty indicator slots
anymore.

CHANGES FOR VERSION
4.22.0 (as compared to 4.21.1)
changes made in Indicator Builder are not lost if formula is incorrect -
instead error message is displayed and formula is saved even if it has a
syntax error
if currently displayed indicator formula has an error - the error message
does not pop up in a separate window but is displayed in the indicator pane.
empty indicators are not displayed in the Indicator Builder and new
buttons "Add", "Delete" are provided to add new indicator and remove existing
when drawing or moving drawing objects the auto-refresh of the chart is
temporarily held to solve problems with drawing on RT charts.
Symbol->Information window is not reset every 3 sec when working with
RT data.
interval between chart updates is now configurable
(Preferences->Intraday)
Random( seed = none ); function takes new parameter seed.If seed is
defined it initializes the seed of random number generator this allows to
produce repetitive series of pseudo-random series. If seed is not specified -
random number generator continues generation.To reinitialize the
generator, use 1 as the seed argument. Any other value for seed sets the
generator to a random starting point. Example 1:Graph0 = Random();
// generates different sequence with each refreshExample 2:Graph0
= Random(1); // generates the same sequence with each refresh
new AFL function PlotShapes( shape, color, layer = 0, yposition =
graph0 );that allows to plot arrows and other shapes on any
chart.Parameters:
shape defines type of the symbol. when shape is zero nothing is
plottedvalues other than zero cause plotting various pre-defined
shapes.Odd values plot shape BELOW indicator, even values plot shape
ABOVE indicator.
color defines color of shape
layer defines layer number on which shapes are plotted
yposition defines Y-position where shapes are plotted (by default
they are plotted 'around' graph0 (first indicator) line)
Currently defined shapes areUP ARROW = 1, (below
