right) lines 
Format toolbar controls (color, thick, dotted) change selected drawing 
style & color 
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 cursor is 
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 selectmode 
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.

that operations) 
X-coordinate display pane in status bar enlarged to accommodate time 
also

format so you can resize copied picture without distortion. (useful for 
creating documents that are printed later)

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)

fixed bug with date axis display that appeared in 4.15.0 
fixed problem with moving/sizing objects when multiple windows wereopen 

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 indraw 
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 can 
NOT 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 to 
full hours custom bar intervals of more than 60 minutes 
Layouts->Save As does not generate duplicate entries in the treewhen 
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 sectionof 
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 thisin 
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 layout 
name 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 #include 
that 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 slowdown 
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.
