Hi Thomasz,
i know here is not the right place to make a suggestion.But in replay
of this I must answer.I also would be happy if we can have a Square of
nine or a square of 144 Calculation in Ab available.
Its a Importend Instrument for Forex and Stocks/Commodity to.I
calculate it in a Excel spreadsheed.
With the square of nine you can calculate support and resistence level
with an ultraprecision over long time , most like writen in stone.The
Gann instruments are for an Invetor the best of all available Forecast
Instruments.If i study it ,i could not belive how ultraprecision
forecasting is possible.I understand later that the Theorie of Gann
is context with politics,fibonacci,Universum,Wars,economy and also
with our live.
If you bring this Instruments to AB ,this will be a big advantage for
AB. I think we can not have all possibilities of Gann in AB ,because
some needs a spezial calculation of the time axsis.
If you are Intressted i can send you material about calculations of
square of 9/144.
Best regards
Dieter

numbers.It returns True if x and y are equal or almost equal upto
defined accurracy (ulps).It is recommended to use this function
instead of equality check (==) as itleads to more reliable comparisons
and less headache caused by IEEE floating pointacurracy issues.
>
> Parameters:x, y - the numbers or arrays to be compared,Ulps
stands for "units in last place" and represents maximum relative error
of the comparison. Since 32 bit IEEE floating point numbers have
accurracy of 7 significant digits, 1 unit in last place(ulp)
represents relative error of 0.00001 %. The default value of ulps
parameter is 5 which gives roughtly 0.00005% "comparison sensitivity".

(completed: 2005-09-09)
> Number of decimal places displayed in default chart title is
now user-definable inTools->Preferences->Miscellaneous"Decimal places
in chart titles".
>
> Allowable values:
> -1 - dynamic mode (number of decimal places automatically
adjusted)
> 0..6 - fixed number of decimal places
>
>
> p.. QuoteArray resizing now uses heuristic algorithm to
minimize memory fragmentation and increase performance
>
>
> q.. atcFlagDeleteValues now highlighted properly in the AFL editor
>
> CHANGES FOR VERSION 4.71.1 (as compared to 4.71.0)
>
> a.. fixed compatibility problem with AmiQuote (due to changed
order of OLE properties/method while AmiQuote was using old ones)
> b.. now ASCII importer in $TICKMODE does not delete quotes
older than oldest (first) record in the imported file, so you can
safely import tick data from subsequent files (older first, newest later)
> CHANGES FOR VERSION 4.71.0 (as compared to 4.70.5)
>
> a.. AFL: added GetCursorXPosition() and GetCursorYPosition()
functions
>
> Functions return current mouse cursor position.
> Values returned are equal to those visible in the status bar,
and these functions require status bar to be visible. Returned values
represent cursor position at the formula execution time (or few
milliseconds before it) and accurracy is subject to pixel resolution
of the screen (first cursor position is read in screen pixels
(integer) and then converted to actual value therefore for example
when screen resolution is 1024x768 maximum obtainable resolution in X
direction is 0.1% and in Y direction 0.13%), also X values are snap to
datetime of nearest data bar.
>
> It only makes sense to use these functions in
indicator/interpretation code.
>
> Using them in AA window may yield random
values.GetCursorXPosition() function returns X position in DateTime
format (the same as used by DateTime() function).You can convert it to
string using DateTimeToStr() function.GetCursorYPosition() returns Y
position (as displayed in Y axis of the chart).
>
> Example:
>
>
> ToolTip="X="+DateTimeToStr(GetCursorXPosition())
+"\nY="+GetCursorYPosition();
>
>
> b.. AFL: added DateTimeToStr() and StrToDateTime() functions
>
> These functions allow to convert string to datetime format and
vice versa.
>
>
> Example:
>
> ToolTip="X="+DateTimeToStr(GetCursorXPosition())
+"\nY="+GetCursorYPosition();]
>
> c.. Added ability to store charts as .GIF (in addition to PNG)
>
>
> d.. ASCII importer maximum supported line length is increased
to 2048 characters
>
>
> e.. Fixed: .aflsafe files didn't get deleted automatically
>
>
> f.. Added N-volume bars charts and timeframe support.
>
> Custom N-volume bar intervals are definable (as usual) in
Tools->Preferences->Intraday.
>
> TimeFrame functions were also extended to support N-volume
bars using new TimeFrameMode() function calling
>
> TimeFrameMode( 0 );
>
> - switches time frame functions to time-based operation (the
default)
>
> TimeFrameMode( 1 );
>
> - switches time frame functions to N-tick operation (positive
values passed to TimeFrameSet are treated now as N-tick)
>
> TimeFrameMode( 2 );
>
> - switches time frame functions to N-volume bar operation
(positive values passed to TimeFrameSet are treated nowas N-volme bars)
>
> Example:
>
> TimeFrameMode( 2 );
> TimeFrameSet( 50000 ); // 50'000 share bars..
> ...do something ...
> TimeFrameRestore();
>
>
> Note: N-volume bars are somewhat weird (compression of data to
N-volume bar may actually deliver MORE output bars - for example if
one tick is 1000 shares and you have specified 100V bars then single
tick will be expanded to TEN 100V bars - ten times original size)
> TimeFrame functions are protected against array overrun and
will not decompress beyond original array size (you will get an "Error
47. N-volume bar compressed data longer than base time frame").
> Also switching main time frame to some weird N-volume bar
value will result in limiting the output to maximum twice original
data size(without error message).
> You should keep that in mind and avoid using too small
N-volume bar intervals that could lead to such condition.
> Also due to the nature of N-volume bars the only
TimeFrameSet() function will yield correct N-volume bar values,
TimeFrameGetPrice() may give slightly distorted results.
> It is also possible to use n-volume bars in TimeFrame
functions without calling TimeFrameMode() - it is then necessary to
specify n-volume bars as negative number offset by -1000000 (minus one
million):
>
> TimeFrameSet( -1000000 - 2000 );
>
> // gives 2000V barsSimilarly formatted negative numbers will
be reported by Interval() function when n-volume bars are selected.

> It has some restrictions on size: specified size can not
besmaller than 10x10 pixels and can not be bigger than entire screen
dimensions.
> Also when "No minimum size for resizing dialogs" box in
UNCHECKED in Tools->Prefs->Misc it won't shink AA window below default
size necessary to fully display all controls.

>
> l.. ASCII importer: added ability to import tick data from
text files
>
> ASCII importer now allows tick data files to be imported.
>
> Tick data files consist of several records having the same
timestamp.This makes it impossible to use normal import mode which
assumes different (unique) timestampsfor each data row (when same
timestamp is found then new data overwrites old).

> $TICKMODE 1
>
> line to ASCII importer definition file.
>
>
> $TICKMODE is a special mode of importer that allows to import
quotes that haveduplicate time stamps.
>
> It makes two assumptions:
> a) input data should come in the ascending time order (i.e.
OLDER records first, LATEST records last)
> b) input data should consist of entire tick history because
importer will DELETE any existing quotes (to avoid creating multiple
copies of the same ticks).
>
> Once again: Turning on
> $TICKMODE 1
> will DELETE ANY QUOTES that already exist in the database and
then will import all ticks from input data file.
> You have been warned.

>
> For example data files like this:
>
>
MOL,0,20050606,162959,16400.0000,16400.0000,16400.0000,16400.0000,2MOL,0,20050606,162959,16400.0000,16400.0000,16400.0000,16400.0000,11MOL,0,20050606,162959,16400.0000,16400.0000,16400.0000,16400.0000,40

> Can be imported using the following definition file:

> $FORMAT Ticker, Skip, Date_YMD, Time, Open, High, Low, Close,
Volume
> $SKIPLINES 1
> $SEPARATOR ,
> $CONT 1
> $GROUP 255
> $AUTOADD 1
> $DEBUG 1
> $TICKMODE 1
>
>
> Sometimes it happens that input files have invalid timestamps
(seconds > 59).
>
> For example:
>
>
MOL,0,20050606,162970,16400.0000,16400.0000,16400.0000,16400.0000,2
>
> Please take a closer look at first line shown in this example
it has time:16:29:70 (you see 70 seconds !)
>
> So I had to add a special flag to the importer that works
around such data errors.
>
> It is called $ALLOW99SECONDS 1 and will convert all records
with invalid seconds (i.e greater than 59)to 59s.
> So record stamped 16:29:70 will be treated as 16:29:59
>
> Now for tick mode to work with such incorrect records you
would need to add two lines to ASCII importer definition:
>
> $TICKMODE 1
> $ALLOW99SECONDS 1
