Tomasz,
The following code produces different symbols than the code is
referring to, in this case circles and stars:
PlotShapes( shapeUpArrow * Buy + shapeDownArrow * Sell, IIf( Buy,
colorGreen, colorRed ) );
I tried several combinations it seems that the references are mixed
up.
Does anyone have the same problem with this release?
regards,
Frans.

bars too. N-tick intervals are specified by NEGATIVE numbers passed
in 'interval' parameter.

renaming, creation of new files and folders plus more via Right-
mouse button (RMMB) menu. Options available from RMB menu:

_SECTIONS if necessary and inserts charts into new pane

pane links directly to selected formula (so if you have more than
one pane using the same formula, modifying it will modify the chart
in all panes linked to it)

too (you can drag formulas and AFL files onto it)

for example profit target stop is hit on the same bar then profit
target is evaluated first)
> If ExitAtStop = 1 then N-bar stop has highest priority and it is
evaluated before all other stops.
> The same effect is obtained by checking "Has priority" box in AA
Settings window.

> d.. new maximizing/restoring chart pane functionality available
via:
> View->Pane->Maximize
> View->Pane->Restore
> as well as via right click menu.

> Remember that you can assign your own keyboard shortcuts for
that using Tools->Preferences->Keyboard

> e.. New drawing tool: Arrow
> - draws a line that ends with an arrow
>
> f.. New drawing tool: zig-zag line
> draws a series of connected trend lines (Hint: press ESC key to
finish the series)
>
> g.. new File functions in AFL:
>
> a.. fdelete( "filename" ) - deletes file
> "filename" is path to the file name (relative or full path).
> If just file name without path is specified then AmiBroker
directory is used, returns TRUE if file successfully deleted, FALSE
otherwise
>
> b.. fmkdir( "dirname" ) - creates (makes) a directory
> "dirname" specifies path of the directory to be created.
Please note that this function creates only ONE directory at a time.
> So if you want to create nested directory tree you have to
call it multiple times, for example to create
C:\MyDirectory\MySubDirectory folder you have to call it twice:
>
> fmkdir( "C:\\MyDirectory" );
> fmkdir( "C:\\MyDirectory\\MySubDirectory" );
>
> Note also that it is safe to call it even if directory already
exists (then no change to file system is applied)
> Returns TRUE if directory successfully created, FALSE otherwise
>
> c.. frmdir( "dirname" ) - removes a directory
> "dirname" specifies path of the directory to be removed.
Please note that this function removes only ONE directory at a time.
> So if you want to remove nested directory tree you have to
call it multiple times, for example:
>
> fmkdir( "C:\\MyDirectory\\MySubDirectory" ); // delete nested
subdir first
> fmkdir( "C:\\MyDirectory" );
>
> Note that directory must be empty before removing it otherwise
it will not be possible to remove it.
> Returns TRUE if directory successfully removed, FALSE
otherwise
