Bill,
Note that "Format" toolbar now works so it allows youto
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.
Understand. What I was trying to
say is if one could specify right extension, left extension, both extension,
or segment before drawing then only one line icon would be needed.
Putting these options in the toolbar takes a lot of space, but right clicking
on the icon to get to the options would free up space. Thick, dotted,
normal might also fit into this category. Anyway, just a
thought.
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 the end) but I like it. Seems to make some drawing much
easier. Unless I'm missing something, it should be possible to provide
only the extension tool, if one could, for example, right click onthe
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

<SPAN

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 is
free 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).

AmiBroker 4.17.0 Beta Read Me
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.
CHANGES FOR
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 onlyif
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 recommendations
for 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 menuis
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)
completely re-designed Fibonacci retracement tool allowing full
customization and more flexibility. Just draw a Fib retracementand
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 accessibleonly
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 ona
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 parametersfor
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// Nowplot
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 regressionline
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
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 layout name in the "Layouts" tab of the Workspace
window
you can open/save/delete layout by clicking on the Layouttree
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 - newQT
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
