Bill,
 
Note that "Format" toolbar now works so it allows you to 
select
color, thick/dotted and snap to price BEFORE 
drawing
AND
(if you select any already drawn object) allows you also to 
select
its color, thick/dotted style AFTER.
 
So it is the best of two worlds.
 
Note also that only Fib/Gann tools provide more settings than 
mentioned
above and showing properties before drawing would make sense 
only
for these tools. (I will think how to add this in non 
obtrusive way :-))
Best regards,Tomasz Janeczkoamibroker.com

Jayson:
 
Great improvements in charting, although I may not 
have found everything yet.  As for ray vs trendline, actually, ray, 
trendline, and extension are related.  I have not seen the ray/extension 
work the way they do (like a flashlight beam instead of holding on to theend) 
but I like it.  Seems to make some drawing much easier.  UnlessI'm 
missing something, it should be possible to provide only the extension tool, 
if one could, for example, right click on the icon and choose the 
properties before drawing.  This would eliminate two icons and still 
provide all of the tools.  The parallel lines also make life much easier, 
and everything seems to be working smoother.  4.17 is a big step 
forward for my type of analysis. 
 
Bill
 
P.S. Tomasz, clicking on the icon to choose 
properties before drawing would be desirable for all drawing 
tools.

<SPAN 
class=194334121-02102002>Bill,
have you 
looked at the new ray drawing tool in the new beta? If "Snap to price" is 
turned off then a trend line can be drawn any where (although I use it as 
you describe. The new Ray drawing tool seems to do the same thing. I am 
sure I am missing the point, but that in its self is not highly 
unusual......
<SPAN 
class=194334121-02102002> 
No, 
I'll look.

Jayson:
 
In my world, a trendline is relative to 
price/indicator data (H to H, L to L, H to L, etc.), whereas a ray isfree 
as a bird and assumes values that you conjure up (e.g., Gann 1x1, etc.) or 
are related to some aspect of non-price data constructions (e.g., Gann 
box).

October 2, 2002 20:45 

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 4.00 first. 
Just run the installer and follow the instructions. 
Then run AmiBroker. You should see "AmiBroker 4.17.0 beta" written in 
the About box.
CHANGESFOR 
VERSION 4.17.0 (as compared to 4.16.0)
added Gann Square and Gann Fan drawing tools with customisation 
dialogs (angle of line is displayed in the status bar) 
added parallel trend line tool 
studies can be dragged without "shrinking" effect beyond upper and 
lower chart border and beyond left and right border (but within 
available quotation range plus right margin) 
New toolbar buttons for ray (right-extend line) and extend (left 
and 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 
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 recommendationsfor 
user interface, 
moved "snap to price" to Format menu and moved "Erase watch 
lists" to "Symbol" menu. 
"Snap to price" now available from toolbar. Right and left 
extend available from Format menu. 
Added "Properties" and "Delete all" to "Edit" for consistency 
"Quotations..." has been renamed to "Quote Editor" and toolbar 
icon has been changed 
certain rarely used toolbar icons from "main toolbar" were 
removed to 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 quotesfrom 
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 wantto 
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 
CHANGESFOR 
VERSION 4.16.0 (as compared to 4.15.1)
completely re-designed Fibonacci retracement tool allowing full 
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. 
CHANGESFOR 
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) theold 
functionality (pick quotation) is available if you hold down CTRLkey 
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. 
CHANGESFOR 
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) 
CHANGESFOR 
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 styleback 
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 withthe 
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)
CHANGESFOR 
VERSION 4.13.1 (as compared to 4.13.0)
F4 key for Edit | GoToSymbol works again and can be redefinedin 
the shortcut editor 
new style: styleLeftAxisScale = 65536 - allows to plot morethan 
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) 
CHANGESFOR 
VERSION 4.13.0 (as compared to 4.12.0)
fixed bug with loading layouts for stocks that have spaces inthe 
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 
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.
CHANGESFOR 
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 colorsin 
the string.Colors can be specified using \\cXX sequence whereXX 
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 
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") 
old single-window layouts are now renamed to "templates" 
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 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. 
Intraday settings dialog allows wider time shift -23..+23 hours
