CHANGES FOR VERSION
4.17.0 (as compared to 4.16.0)
added Gann Square and Gann Fan drawing tools with customisation dialogs

snap to price was not accurate in v4.15-4.16 now it is accurate again
snap to price now works in "magnet" mode - so it snaps only if cursoris
within 5% distance to high/low price. Snap % threshold is definable in
Preferences/Charting
usability improvement: even when "return to select mode after drawing" is
ON, you can draw mutliple studies one after another quickly if you hold down
CTRL key while releasing the button.
usability improvement: you can now draw objects with OR without holding
left mouse button pressed while drawing.
drawing object is now automatically selected when "return to select mode
after drawing" is ON and "auto-select last drawn object" is also ON. This
makes it easier to delete/copy/cut or see its properties (Alt+Enter)
immediatelly.
#include can now be written also in upper case
some UI clean-up:
added "Format" menu just to conform with MS recommendations for user
interface,

available from Format menu.
Added "Properties" and "Delete all" to "Edit" for consistency
"Quotations..." has been renamed to "Quote Editor" and toolbar iconhas
been changed

save space (Add/Delete/Split Symbol - regular menu is more appropriate for
that operations)
X-coordinate display pane in status bar enlarged to accommodate time also
added "Copy Image as Metafile" option to Edit menu. Metafile is a vector
format so you can resize copied picture without distortion. (useful for
creating documents that are printed later)
Quote Editor (QE) improvements:
you can now delete quotes in QE - select one or more quotes from the
list (SHIFT/CTRL to multi-select) and press "Delete" button
QE made several times faster displaying 20'000 bars in "current" symbol
mode takes about 2 seconds now.
now tickers can be case-sensitive. This is useful if you want to treat.
ABC and ABc as different symbols. Tools->Preferences "Miscellaneous" :
"Case sensitive ticker symbols"USE WITH CARE AS CERTAIN PLUGINS (eSignal
plugin for example) DO NOT HANDLE CASE SENSITIVITY
CHANGES FOR VERSION
4.16.0 (as compared to 4.15.1)

customization and more flexibility. Just draw a Fib retracement and double
click on it (or choose Edit->Properties). Customization dialog is available
on "Fibonacci" tab.
new setting in Tools->Preferences->Charting "Select quote only by
CTRL+LMB" - if marked quote selection is accessible only via double click
or single click WITH CTRL key depressed (v4.15 style).if unmarked quote
selection is possible via single click (old style)
trend line properties dialog moved to property sheet for consistency.
CHANGES FOR VERSION
4.15.1 (as compared to 4.15.0)
fixed bug with date axis display that appeared in 4.15.0
fixed problem with moving/sizing objects when multiple windows were open
removed "Move/Size" toolbar button:now editing/moving/sizing is
enabled by default in regular "Select" mode (arrow cursor) the old
functionality (pick quotation) is available if you hold down CTRL key while
clicking once on the chart or by double click on a chart while not being over
an object. Double click over object - shows properties.
added "Return to select mode after drawing" option in
Tools->Preferences->Charting- when it is switched ON (by default) -
right after drawing any object it is available for moving/sizing/deletion.
CHANGES FOR VERSION
4.15.0 (as compared to 4.14.0)
moving and sizing of drawing objects (see new "Move/Size" button in draw
tool bar)
cut/copy/paste/delete of drawing objects (Edit menu and standard
shortcuts, need to mark object first in Move/Size mode)
blank space in the right-hand side of the chart for drawing future trend
line projections
moved charting related preferences setting to new tab "Charting"
new setting for number of blank bars in right margin (Charting tab)
CHANGES FOR VERSION
4.14.0 (as compared to 4.13.1)
fixed problem with creating new databases that occurred on certain MSVCRT
versions
styleOwnScale adjusts Base level for histogram and area style back to
minvalue or zero whichever is less
Plot, PlotOHLC and PlotForeign have 2 additional parameters for specifying
fixed minimum and maximum values for Y-axisNote that new parameters work
only when styleOwnScale is used:Plot( array, title, color, min = {empty}, max = {empty} )PlotOHLC( open, high, low, close,
title, color, min= {empty}, max = {empty} )PlotForeign(
ticker, title, color, min= {empty}, max = {empty}
)New parameters make it easy to plot ribbons, for example:
Plot( Close, "Price", colorBlue, styleCandle );Plot( 2, /*
defines the height of the ribbon in percent of pane width
*/"Ribbon",IIf( up, colorGreen, IIf( down, colorRed, 0 )), /* choose
color */styleOwnScale|styleArea|styleNoLabel, -0.5, 100 );
It also makes it easy to plot 2 or more "own scale" plots with the same
scaling:
minimum = LastValue( Lowest( Volume ) );maximum = LastValue(
Highest( Volume ) );
Plot( Close, "Price", colorBlue, styleCandle );
/* two plots below use OwnScale but the scale is common because we
set min and max values of Y axis */Plot( Volume, "Volume", colorGreen,
styleHistogram | styleThick | styleOwnScale, minimum, maximum );Plot(MA(
Volume, 15 ), "MA volume", colorRed, styleLine | styleOwnScale, minimum,
maximum );
fixed date axis display for custom intraday intervals longer than 60
minutes
"dirty" flag is set properly now during ASCII import in $OVERWRITE 1 mode
(solves import watch list problem)
when switching layouts ticker bar selection is now synchronized with
active window
after AA->Scan Foreign symbol cache is flushed
now styleLeftAxisScale really allows modification of built-in price chart
to feature moving average of volume// Now plot volume and its moving
average using left-hand axis scalingPlot( Volume , "Volume", colorBlue,
styleLeftAxisScale | styleHistogram | styleThick | styleNoLabel );Plot(
MA( Volume,15), "MAV", colorLightBlue, styleLeftAxisScale | styleNoLabel
);
ASCII importer and Import Wizard now allows to import negative prices
(useful for spreads). New command is $ALLOWNEG 1 and new check box in Import
Wizard is "allow negative prices". Please note that logarithmic scale canNOT
be used to display negative prices because log() function is undefined for
negative values.
four new AFL functions:
LinRegIntercept( ARRAY, periods )- calculates intercept of linear
regression line the "a" coefficientin a + b*x (LinRegSlope calculates b)
LinearReg( ARRAY, periods )- calculates linear regression line ending
value according toa + b * x (where a and b are intercept and slope of
linear regression line)
StdErr( ARRAY, periods )- calculates standard error function (standard
error of linear regression estimate) - the same as MS' STE function
TSF( ARRAY, periods ) - calculates time series forecast indicator
(similar to LinearReg but differs bythe value of lin reg
slope)
CHANGES FOR VERSION
4.13.1 (as compared to 4.13.0)
F4 key for Edit | GoToSymbol works again and can be redefined in the
shortcut editor
new style: styleLeftAxisScale = 65536 - allows to plot more than one graph
using common scaling but different from regular (right axis)
scale.Example: price plot plus volume and moving average plot:
// Plot price plot and its moving averagePlot( Close, "Price",
colorWhite, styleCandle );Plot( MA( Close, 20 ), "MAC", colorRed
);
// Now plot volume and its moving average using left-hand axis
scalingPlot( Volume , "Volume", colorBlue, styleLeftAxisScale |
styleHistogram | styleThick );Plot( MA( Volume,15), "MAV", colorLightBlue,
styleLeftAxisScale );
(in one of the future betas you will be able to display ruler for
left-hand axis)
CHANGES FOR VERSION
4.13.0 (as compared to 4.12.0)
fixed bug with loading layouts for stocks that have spaces in the ticker
symbol
new pre-defined shortcut keys: Alt+Left = Next symbol, Alt+Right = Prev
symbol,Ctrl+NumPadPLUS = Zoom In, Ctrl+NumPadMINUS = Zoom
Out,Ctrl+PageUp = Prev Sheet, Ctrl+PageDown = Next Sheet
new keyboard shortcut editor in Tools->Preferences->Keyboard allow
user-definable keyboard shortcuts
fixed display bug in Preferences->Intraday that caused rounding tofull
hours custom bar intervals of more than 60 minutes
Layouts->Save As does not generate duplicate entries in the tree when
already existing name is typed in (it was harmless but still not nice)
A confirmation box is displayed when choosing Edit->Delete session
fixed problem with incorrect interval shown in the settings section of the
report when hourly periodicity was selected
new style: styleOwnScale = 32768 allows plotting graphs with independent
scalling (like volume graph on price plot)
implemented PlotForeign("ticker", "title", color, |
styleOwnScale )
implemented PlotOHLC( open, high, low, close, "title", color, | styleOwnScale ) that allows plotting candlesticks/bars from
other arrays without need to overwrite existing OHL arrays.
CHANGES FOR VERSION
4.12.0 (as compared to 4.10.3)
color coded and multi-line caption bars in indicatorscolors are
selected automatically when using Plot() function or graphNcolor
variable.If you use Title variable you have to specify colors in the
string.Colors can be specified using \\cXX sequence where XX is 2 digit
number specifying color index \\c38 - defines violet, there is a special
sequence \\c-1 that resets to default axis color. For example
Title = "This is written in \\c38violet color \\c27and this in
green";You can also use new AFL function that makes it easier.
Function is calledEncodeColor( colornumber ).And you can write the
above example like this:Title = "This is written in " + EncodeColor(
colorViolet ) + "violet color " + EncodeColor( colorGreen ) + "and this in
green"; Multi-line caption is possible by simply embedding line break
\n, for example:Title = "This is 1st line\nThis is second line";
new layout handling code:
you can now have unlimited number of custom, multiple-window
templates that can be switched between with just double click on layoutname
in the "Layouts" tab of the Workspace window
you can open/save/delete layout by clicking on the Layout tree with
right mouse button and choosing appropriate function. "Save As" option saves
current layout under new name.
Local layouts are per-database while Global layouts are visible from all
databases.
information saved in layouts include: window sizes and postions,
maximized/minimized state chart panes available on each sheet (independent
for each window), selected bar interval, selected symbol, selected chart
sheet
Most recently used layout can be saved on exit and database switch
automatically (see: Tools->Prefs->Miscellaneous "Save on exit:
Layouts")
CCIa( array, period ) function added - works like CCI but accepts input
array instead of working on (C+H+L)/3
implemented a *very* basic pre-processor with single command #includethat
allows to include external AFL files into your formula. Syntax:#include
"path\to my file\name path.afl"Note 1: include statement need SINGLE
backslashes in the path (this is quite the opposite to normal AFL
stingparsing)Note 2: using #include command may slow down formula
execution evenconsidering the fact that AmiBroker tries to include only
once and cache pre-processed textNote 3: that currently no error message
is given if #include fails and this codeis experimental.Note 4:
nesting #include commands is not supported
balloon tooltips for status bar
color-coded plugin status pane in the status bar, plus pop-up balloon
notifications when connection state changes
ability to link custom menu to the plugin status pane - new QT plugin
(beta) provides Connect/Shutdown options thru such menu.
data plugins receive UNLOAD notification correctly
you can sort columns in Quotation Editor by click on column header
layout of Quick Review window changed to allow smaller window size.
