QuickAFL was enabled
fixed problem occuring when Nth greater than 1 was used with PeakBars,
TroughBars
'Check' feature in AA window does not consider Equity() function as
referencing future
CHANGES FOR VERSION
4.07.3 (as compared to 4.07.2)
fixed bug causing crash when LastValue() was used and QuickAFL enabled
reduced memory usage of AFL when evaluating expressions like expr1
(operator) expr2 when one of expr is a number (scalar) and another variable is

fixed bug causing crash when using formula with Equity() function and
QuickAFL enabled
fixed bug causing crash when using variable-period HHV,LLV functions and
QuickAFL enabled
fixed invisible short/cover arrows problem (arrows are shifted into
visible area now if there is not enough space)
overlaid indicators re-evaluate number of bars required to calculate
formula so for example longer averages added to main chart via custom AFL
formula are plotted correctly for all bars
new Status() fields "range...." now work also in Scan and Exploration
modes
text columns in Explorations are sorted correctly by click on the header
CHANGES FOR VERSION
4.07.1 (as compared to 4.07.0)
Equity plot does not generate alerts anymore
SOUND command works now (previously only PLAY was working). Additionally
an error message is displayed in the status bar when something goes wrongwith
playing the audio alert. Please note that you should use \\ (double slashes)
in the paths in AlertIF function
CHANGES FOR VERSION
4.07.0 (as compared to 4.06.1)
help window is detached from application window
arrows generated by commentary window are refreshed properly when newrt
bars arrive (arrows are shown for active symbol only)
e-mail alerts: support for servers requiring SMTP authentication.
Supported methods:AUTH LOGIN (most popular), POP3-before-SMPT (popular),
CRAM-MD5, LOGIN PLAIN
sound alerts: ability to test sound output in
Tools->Preferences->Alerts
AFL error box popping up in AA when RT data are flowing does not cause a
crash
custom minute bar compression improved - now you can have >60 minute
bars and also bars not evenly dividing the hour. So you can have 39 or 73
minute bars for example
drawing date/time axis improved
drawing built-in charts optimized for very long histories
new AFL functions:+ Interval() returns bar interval in seconds+
RMI( periods = 20, momentum = 5 ) - Altman's Relative Momentum Index (S&C
Feb 1993)+ Status() function features new fields:"rangefromdate",
"rangetodate" - return current auto-analysis From-To range as DateNums
"rangefromtime", "rangetotime" - return current auto-analysis From-To
range as DateNums "barinrange" - returns 1 when current bar is within
current auto-analysis From-To range"barvisible" - (custom indicators only)
returns 1 when current bar is visible in current view note: this should be
used only if you really have to, indicator should bewritten without need
to know how it is displayed+ LastValue has new optional
parameterLastValue( array, forcelastbar = 0 );forcelastbar - changes
the behaviour of LastValue when used in Commentaryor Interpretation
windows. By default it uses selected value, but if youuse LastValue(
array, True ) then it always use last bar instead of selected one.+
SelectedValue( array )
selection bar updates caption in all chart panes (displaying current
values of all indicators). you can move selection-bar with <- and ->
cursor arrows on keyboard as before but now when you reach left most or right
most bar- the chart starts to scroll automatically
quote selection and caption display works different now: if selection-bar
is NOT visible then the last VISIBLE bar data are displayed (not the LAST
available), if selection-bar visible then selected bar data are displayed
new graph >- plots point-and-figure-style O and X symbols
instead of candlesticksHigh and Low table are used to determine the height
of bar,Close-Open distance determines box size. If Close > Open - X's
are drawnif Close < Open - O's are drawn.
added bitwise-and '&' and bitwise-or '|' operators to AFL language
(note that floating point number are converted (truncated) to integers before
applying bitwise operators)
CHANGES FOR VERSION
4.06.1 (as compared to 4.06.0)
fixed tab order in Analysis window (Range radio buttons) (appeared in
4.06beta)
fixed problem with using AFL.Var with uppercase letters (appeared in
4.06beta)
fixed problem with using gSite.SetVariable / gSite.GetVariable with
uppercase letters (appeared in 4.06beta)
fixed problem with exploration (appeared in 4.06beta)
fixed small display issue in the data tooltips (-1e10 displayed instead of
{EMPTY})
CHANGES FOR VERSION
4.06.0 (as compared to 4.02.1)
New Interpretation window (View->Interpretation) displays
chart-sensitive commentaries
new AlertIF function allows to generate visual, sound, e-mail alerts.It
also allows to launch any external program on signal generated by AFL formula.
Automatic Analysis window now allows periodical scans (Scan every n
minutes)
new Check feature in Automatic Analysis window allowing you to find out if
your formula references future quotes or not.
Data tips show indicator values now and can show also interpretationsof
indicators
n QuickAFL technology implemented (Tools->Preferences->Miscellaneous
-> Enable QuickAFL for indicators) - provides >10x speed-up in custom
indicator charting with long histories (>1000 bars)
ability to modify / overlay additional graphs over built-in charts
(Indicator Builder->Built-in tab)
ability to create your own interpretation commentaries in Indicator
Builder
new AFL functions:
AlertIf( BOOLEAN_EXPRESSION, command, text, type = 0, flags = 1+2+4+8,
lookback = 1 );
SetBarsRequired( backward, forward= -1) - overwrites heuristic guessing
algotithm used by QuickAFL technology. Allows to specify the number of
previous (backward), and future (forward) quotes required by the formula to
properly calculate - for advanced users only
GetBaseIndex() - retrieves symbol of base index as defined in
Symbol->Categories. To plot base security chart just use graph0 =
Foreign( GetBaseIndex(), "C" );
EnableTextOutput( flag ) - enables output of strings into commentary /
interpretation window. When flag = 0 no string is printed into commentary
window, 1 - strings are printed
_N( text ) - the function that prohibits writing the values of
assignment of string variables: _N( text = "this is a text" ); this does not
print out the text being assigned into commentary window.
filtering weekends (File->Database Settings->Intraday
settings->Filter weekends)
Commentary and Interpretation window are automatically refreshed when
charts are refreshed
OLE automation Quotation.Date (GetDate) includes time also
AFL engine symbol lookup optimized so AFL engine initializes 2x faster and
symbol lookup is also faster
when scrolling zoomed-out chart (that displays more than 2048 data bars)
the refresh is delayed a little. This makes scroll bar more responsive and it
takes much less to scroll to desired position when working with >100000
bars.
CHANGES FOR VERSION
4.02.1 (as compared to 4.02.0)
added automatic ruin stop that closes all trades loosing more than 99.96%
CHANGES FOR VERSION
4.02.0 (as compared to 4.01.0)
added ability to filter after-hours trading (File->Database
Settings->Intraday settings : Filter after-hours box plus definable session
start/end (per-workspace settings)
added ability to shift time displayed on charts/dialogs File->Database
Settings->Intraday settings : Time Shift (AmiBroker uses computer local
time, so it displays realtime quotes using the time of the timezone you are
in. For example if you live in Warsaw - NYSE-quotes stocks will start 15:30
local (Warsaw) time. If you want however to display time as it is in New York
(-6 hours -> 9:30) you have to set Time Shift to -6.
fixed problem with importing very long intraday histories > 300000bars
(if you want to import that long histories you have to go to File->Database
Settings and change "Default number of bars" to at least 3000)
fixed a bug in intraday -> daily time compression
fixed "no trade list" display of Exposure and RAR
when writing the formula to HTML report < and > characters are
encoded to < and > to ensure that formula is not truncated.
"Apply" button in Indicator Builder inserts/modifies the custom indicator
only if the formula is correct. This avoids continuously displayed error
messages when working with real time streaming data.
fixed bug in list view sorting of numeric columns containing small values
fixed crash occuring when Equity() function was called from Commentary
window
fixed display of huge numbers in the chart grid
added option to color up/down (traditional) bars : Preferences -> Main
chart
CHANGES FOR VERSION
4.01.0 (as compared to 4.00.0)
Customisable N-tick
charts in Real Time version (see Preferences -> Intraday tab) and new
View->Intraday menu
Ability to backtest custom N-tick bars
Backtester now makes better decisions on desired order of execution of
signals that occur the same day. (if both buy and sell (or short and cover)
signals occur on the very same bar and there is already open trade from the
any of the previous bars this open trade is closed first, and a new tradeis
opened next. Otherwise the usual order (buy first then sell) is used.
COMMENTS and USAGE HINTS:
Charting engine improvements
Now built-in charts are drawn using even more optimized routines that results
in significant speed up of chart drawing when you display charts for symbols
with more than 30000 quotes. Also QuickAFL is enabled again (and hopefully
bug-free) that gives similar speed up for custom indicators. In addition tothat
selection bar updates caption in all chart panes (displaying current valuesof
all indicators). You can move selection-bar with <- and -> cursor arrows
on keyboard as before but now when you reach left most or right most bar - the
chart starts to scroll automatically. Quote selection and caption display works
different now:
- if selection-bar is NOT visible then the last VISIBLE bar data are
displayed (not the LAST available)- if selection-bar visible then selected
bar data are displayed
Drawing date/time axis works also better now.
New constants and bitwise operators
AmiBroker now includes many pre-defined constants that can make your AFLcode
easier to read. For example you can use the following statements using constants
instead of just numbers:
Plot( MACD()-Signal(), "Histogram", colorRed, styleThick |
styleHistogram );ApplyStop( stopTypeTrailing, stopModePercent, 10, True
);
Using for example colorRed constant will give red color always (regardless of
what palette settings are). Also note that now you can combine chart styleswith
a bitwise-or operator |. Although you can also combine styles with just +
(addition) it is better to use | operator because when you combine the same
style twice by mistake (styleHistogram | styleHistogram) it still works
correctly showing histogram chart ( 2 | 2 = 2 ). Using + in that case will give
2 + 2 = 4 and this is the code for thick style. Complete list of constants is
included later in this document.
In addition to bitwise-or operator | AmiBroker has now also bitwise-and
operator: &. These operators work on binary representation of numbers. Note
that floating point number are converted (truncated) to integers before applying
bitwise operators. Each bit is and-ed or or-ed accordingly. For example 9 is
represented by 1001 binary code and 5 is represented by 0101. Bitwise-or is1101
(13 in decimal) and bitwise-and is 0001 (1 in decimal). Here come a few samples
showing how it works:
255 & 64 gives 64255 | 64 gives 2551 | 2 | 4 | 8 gives 1515 |
7 gives 15
New P&F-like graph style
AmiBroker now features new graph style - 8192 (stylePointAndFigure) that
enables to write formulas that "emulate" point and figure charts. A sample code
is included later in this document. Now just a few comments. New style usesall
open, high, low and close arrays. (OHL indirectly). High array should be set to
bar's highest point, Low array should be set to bar's lowest point. The
Close-Open distance defines box size. If Close > Open then X symbols are
drawn, otherwise O symbols are drawn. Both Close and Open arrays should be
inside H-L range but only the difference between Open and Close really matters
for drawing P&F bars. Please note also that for proper looking P&F
charts the H-L distance should be divisible by box size (C-O distance) without
remainder.
AFL new functions and improvements
Status() function features new fields:"rangefromdate", "rangetodate"-
return current auto-analysis From-To range as DateNums "rangefromtime",
"rangetotime" - return current auto-analysis From-To range as DateNums
"barinrange" - returns 1 when current bar is within current auto-analysis
From-To range"barvisible" - (custom indicators only) returns 1 when current
bar is visible in current view note: this should be used only if you really
have to, indicator should be written without need to know how it is
displayed
For example the system that buys today and sells tommorrow can now be
universally coded as follows:
buy = Status("barinrange");sell = Ref( buy, -1 );
(previously one needed to modify such formula depending on range
settings)
LastValue( array, forcelastbar = 0 ) function has one additional (optional)
parameter: forcelastbar - changes the behaviour of LastValue when used in
Commentary or Interpretation windows. By default it uses selected value, but if
you use LastValue( array, True ) then it always use last bar instead of selected
one. A new function called SelectedValue( array ) gives selected bar value in
Commentary, Interpretation and custom Indicators.
A new RMI( periods = 20, momentum = 5 ) function implements Altman'sRelative
Momentum Index (S&C Feb 1993)
A new Interval() function returns bar interval in secondstick bars =
05 sec bars = 51 min bars = 60hourly bars = 3600dailybars =
86400weekly bars = 430000 (43e4)monthly bars = 2160000
(216e4)
Alerts enhanced
Now "E-mail" page in Tools->Preferences has been renamed to "Alerts" and
allows to define e-mail account settings, test sound output and define which
parts of AmiBroker can generate alerts via AlertIF function.
E-mail setting page now allows to choose among most popular authorization
schemes like: AUTH LOGIN (most popular), POP3-before-SMPT (popular), CRAM-MD5,
LOGIN PLAIN.
"Enable alerts from" checkboxes allow you to selectively enable/disable
alerts generated by Automatic analysis, Commentary/Interpretation and custom
indicators.
Alert output window now has an additional column that shows the source of
alert - if this is Automatic Analysis, Commentary or one of your custom
indicators. This makes it easier to find out which part of AmiBroker generates
alerts.
AlertIF function
AlertIF function is similar to WriteIF. But instead of just writing the text
to the output window (commentary/interpretation) it allows to:
direct the customized text to "alert output" window,
make a sound (just by computer beeper or from .WAV file)
send an e-mail
The syntax is as follows:
AlertIf( BOOLEAN_EXPRESSION, command, text, type
= 0, flags = 1+2+4+8, lookback = 1 );
1. BOOLEAN_EXPRESSION is the expression that if evaluates to True(non
zero value) triggers the alert. If it evaluates to False (zero value) no alert
is triggered. Please note that only lookback most recent bars are
considered.
2. The command string defines the action taken when alert is
triggered. If it is empty the alert text is simply displayed in the Alert
output window (View->Alert Output). Other supported values of command
string are:
SOUND the-path-to-the-WAV-fileEMAILEXEC
the-path-to-the-file-or-URL <optional args>
SOUND command plays the WAV file once.
EMAIL command sends the e-mail to the account defined in the settings
(Tools->Preferences->E-mail). The format of the e-mail is as follows:
Subject: Alert type_name (type) Ticker on Date/TimeBody:
text
EXEC command launches external application or file or URL specified after
EXEC command. <optional args> are attached after file name and text
is attached at the end
3. Text defines the text that will be printed in the output window or
sent via e-mail or added as argument to the application specified by EXEC
command
4. Type defines type of the alert. Pre-defined types are 0 - default,
1 - buy, 2 - sell, 3 - short, 4- cover. YOu may specify higher values and they
will get name "other"
5. Flags control behaviour of AlertIF function. This fieldis a
combination (sum) of the following values:( 1 - display text in the output
window, 2 - make a beep (via computer speaker), 4 - don't display repeated
alerts having the same type, 8 - don't display repeated alerts having the same
date/time) By default all these options are turned ON.
6. lookback parameter controls how many recent bars are checked
Examples:
Buy = Cross( MACD(), Signal() );Sell = Cross( Signal(), MACD()
);Short = Sell;Cover = Buy;
AlertIF( Buy, "EMAIL", "A sample alert on "+FullName(), 1 );
AlertIF( Sell, "SOUND C:\\Windows\\Media\\Ding.wav", "Audio alert", 2 );
AlertIF( Short, "EXEC Calc.exe", "Launching external application", 3 );
AlertIF( Cover, "", "Simple text alert", 4 );
Note EXEC command uses ShellExecute function and allows not only EXE files
but URLs too.
Interpretation window
Interpretation window (View->Interpretation) shows chart-sensitive
commentaries. To add a interpretation just use Indicator builder and add
commentary code after the code for the indicator. Please note that to get the
best performance you should use the following optimization hint: after your
indicator code and before commentary code you should add the following line://--Indicator-End--
( two slashes (comment start), two dashes, Indicator-End and two dashes ).
When the parser is evaluating the formula in the "indicator" mode it stops
there, so commentary code is not executed and it saves time. When parser isin
other modes - entire formula is parsed/executed.
Example:Plot( Close, "Price", -1, 64 ); Plot( SAR( Prefs( 50 ), Prefs( 51 ) ), "SAR",-17, 8+16 ); //--Indicator-End--"The Parabolic SAR provides excellent exit points. ";
"You should Close long positions when the price falls below
the SAR AND Close Short positions when the price rises above the SAR.";
WriteIF( graph1 > Close, "SAR is above close", "SAR is below close" );
Data tips
Data tips now show the values of indicators. Just hover your mouse over the
chart wait a while and data tip will show indicator values at point beneaththe
mouse.
QuickAFL
The QuickAFL technology can give 10x or more speed up when plotting custom
indicators for symbols with more than 1000 bars of data. The exact speed-up
depends on various factors. When evaluating the formula AmiBroker performs a
heuristic guess how many bars of past and future data are required to evaluate
the formula. Then only this required amount is used so when you have a lot of
data (say >50000 data bars) and view only recent 500 bars AFL (if it is
possible) evaluates your formula only for the last few hundreds of bars which is
much faster. Please note that if you are using the following functions: Cum(),
AccDist(), OBV(), Chaikin(), NVI(), Highest(), Lowest(), PVI(), ADLine(),
AddToComposite(), Equity() AmiBroker can not use this optimization technique
because these function perform calculations that require all previous bars.
Please note that AFL can not currently guess the number of bars required by
JScript/VBScript parts of your code nor code included in plugin DLLs. If you are
using any you should take a look at SetBarsRequired function that allows to
instruct AmiBroker how many bars are really needed. Use SetBarsRequired(
1000000, 1000000 ) - if you want all previous and all future bars (old
behaviour).
Please also note that this techniques is currently enabled ONLY for custom
indicators and new Interpretation window. All other AFL tools (Automatic
Analysis, Commentary) are NOT affected.
"Check" feature in Automatic Analysis
As a side effect of the technique of finding out the number of bars required
to calculate given formula, I have added a "Check" feature that parses the
formula in AA window and displays the message telling you what is AmiBroker
guess. It warns you if your formula references future quotes. Note that for
performance reasons the number of past/future quotes required to calculate given
formula is very approximate. The algorithm is actually quite simple. Every
built-in function in AmiBroker "knows" how many past and/or future bars it
requires to calculate properly.
For example Ref( Close, -4 ) "knows" that it requires 4 past bars, and MA(
Close, 15 ) "knows" that it requires 15 past bars. When checking the formula
AmiBroker sums up this individual numbers, so for the following formula:Ref( Cross( MA( Close, 15 ), MA( Close, 25 ) ), -4 );
AmiBroker will tell that you need 44 past quotes (15+25+4). This is morethan
it is really needed, but this is a "safe" guess.
