CHANGE LOG
CHANGES FOR VERSION 4.62.1 (as compared to 4.62.0)
a.. new AFL function
ParamStyle("name", default = styleLine, mask = maskDefault ) - allows to select the styles applied to plot
b.. new constants:
styleHidden - a combination of styleNoDraw | styleNoRescale
styleDashed - dashed line
to be used with ParamStyle
maskDefault - show thick, dashed, hidden, own scale styles (this is default mask for ParamStyle)
maskAll - show all style flags
maskPrice - show thick, hidden, own scale, candle, bar
maskHistogram - show histogram, thick, hidden, own scale, area
c.. colorCycle - accepted only by ParamColor function as default value, causes that default color cycles through red, blue, green, turquoise, gold, violet, bright green, dark yellow
d.. added new setting in Preferences->Charting "Ask for parameters of newly inserted indicators"
(default = TRUE) ensures that AmiBroker displays parameter dialog when inserting or dropping new indicators
e.. removed obsolete "max number of custom indicators" setting
f.. Param() function accepts 6 parameters now
Param("name", defvalue, min = 0, max = 100, step = 1, sincr = 0 );
(Only for advanced users)
a new parameter sincr is defines the increase of default value when more than one section of the same kind is inserted (dropped) onto the chart
For example:
Periods = Param("Periods", 15, 2, 200, 1, 10 );
Plot( MA( P, Periods ), _DEFAULT_NAME(), ParamColor( "Color", colorCycle ), ParamStyle("Style") );
now when more than one moving average is dropped onto the chart then subsequent moving averages default to 15, 25, 35, 45, ... and so on (starting value is 15, increase per new section is 10)
CHANGES FOR VERSION 4.62.0 (as compared to 4.61.0)
a.. implemented indicator drag and drop mechanism. See video tutorial: http://www.amibroker.net/video/dragdrop1.html
b.. new "Chart" tab in the workspace window (lists all AFL files and directories from "Formulas" subfolder)
c.. Automatic Analysis formula window is now drag&drop target too (you can drag formulas and AFL files onto it)
d.. new AFL special functions used to automatically create formulas from code snipplets dragged onto the the indicator pane.
_SECTION_BEGIN, _SECTION_END, _SECTION_NAME, _DEFAULT_NAME, _PARAM_VALUES
e.. new styleNoTitle causing that given Plot name and values are not included in the title bar of the indicator
f.. new ParamField function allowing to pick price field
g.. new ParamToggle function allowing for boolean (Yes/No) parameters
h.. In Tools->Preferences , Keyboard you can how define single key shortcut for maximizing and restoring chart pane via View : PaneToggle
i.. "Allow mixed EOD/intraday data" switch does not affect N-day bars anymore
j.. Parameters are not reset to default values when changing the formula- user-edited values are kept
k.. new parameters dialog allowing using sections (for example from drag&drop generated code)
l.. parameters dialog displays the items in the order as they appear in the formula
m.. fixed Y-axis scale shrinking problem occuring when styleOwnScale was used for all plots
n.. Insert->Standard Charts, Insert->Custom Indicators menu options removed (now everything is handled by drag & drop) (You can still insert old indicators from Indicator Builder dialog though)
CHANGES FOR VERSION 4.61.0 (as compared to 4.60.4)
a.. custom time interval support extended to N-day bars.
Now you can define N-day bars in Preferences (Intraday tab) as well as you can use N-day bars via TimeFrame functions. For example
TimeFrameSet( 3 * inDaily ); // switch to 3-day time frame
VERY IMPORTANT:
inWeekly constant is now 432001 ( 5*inDaily + 1 ) - in previous version it was 432000
inMonthly constant is now 2160001 ( 25*inDaily + 1 ) - in previous version it was 2160000
It is changed because now N-day custom intervals are supported and they will interfere with weekly/monthly.
Note that 5*inDaily is now DIFFERENT than inWeekly. 5*inDaily creates 5-day bars that DO NOT necesarily cover Monday-Friday
while inWeekly ALWAYS creates bars that begin on Monday and end on Friday. Also 25*inDaily creates 25-day bars that DO NOT necesarily represent full month, while inMonthly always begins with first day of the month and ends at the last day of the month
CAVEAT:
if your code uses hard-coded numbers like 432000 for weekly and 2160000 for monthly then you MUST change your code to use inWeekly constant and inMonthly constant instead.
b.. Study properties dialog has now new checkbox
"Lock position" - when checked study can not be moved or re-sized
c.. ExitAtStop has a new meaning for N-BAR stop type.
If ExitAtStop = 0 then N-bar stop has the lowest priority (so if 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
