SDM Chart Layout Language

SDM Chart Layout Language

A Chart is composed out of one or several Windows.
The First/Main Window (Window1) usually display the price and price related indicators (Moving Avg etc.).
You can add up to 19 Windows below the main window, to display other indicators.

Her si an example from the CCITrd.sdc file:
[Window1]
Title=Price
Size=60
Attr=IncModulo:Default|NoGrid
Overlay1=Price|Candle
Overlay2=$TxtLong|TxtDown|Olive

[Window2]
Title=CCI
Size=30
Attr=AxisMax:150|AxisMin:-150|NoGrid
Overlay1=$CCIRaw|Line|SmartColor(100,-100)|1
Overlay2=$CCI|Line|SmartColor(100,-100)|3
Overlay3=Line(100)|Line|Grid|1
Overlay4=Line(-100)|Line|Grid|1

[Window3]
Title=Signal
Size=30
Attr=AxisMax:100|AxisMin:0|NoGrid|IncModulo:50|AbsVal
Overlay1=WarmupStatus|Line|SmartColor(0)|3
Overlay2=Line(0)|Line|Grid|1

Each window is identified by the Section Header [Window{n}] were {n} is the Window Number.
The Sections dont have to be in any order, to temporarily disable a Windows change the
[Window{n}] section header to [xWindwos{n}]

The following details can be specified in each Window Section:

Title

Title displayed for this Window (optional, if not defined the name of first Overlay is used)

Size

Height of the Window in relative units,
In this example the price window is double the height of the indicator windows:
Total units = 120 (60+30+30), Window1=50%, Window2=25%, Window3=25%

Attr

Window Attrributes:

AbsVal	Use the absolute value of the indicators in this window
AxisMin	Fixed value for the vertical Axis Minimum (otherwise dynamically calculated)
AxisMax	Fixed value for the vertical Axis Maximum (otherwise dynamically calculated)
FirstOnly	Use only the first Overlay when calculating dynamically the vertical Axis dimension Example: You want to avoid the Wide Bollinger Band Axis expansion, so you instruct SDM to only use the regular price for the Y Axis Height calculation
IncModulo	Smallest vertical Axis (Price) Increment, Default uses 0.25 for Futures otherwise 0.10
MinZero	Set the vertical Axis Minimum to Zero
NoGrid	Dont display the horizontal grid lines for the vertical Axis Points
Price	Identify this Window as the one and only "Price" window
SymZero	Create the same vertical Axis height for positive as negative range (symetrical around the 0 level)

Overlay{n}

Define the actual indicators the window displays/overlays on top of each other:
{Value}|Type|Color|Width

Value

Defines the Source of the value for this overlay:

$Var	Variable named $Var
$Stop	The current Stop out level, defined in the Exit: section Exit: $Stop = GetPositionExit() See this example (Red dotted line = $Stop)
Line(Val)	Fixed value 'Val'
PositiionExit	Normalized Value of the active Position (if not active Empty) 0=At entry, 50=Half way towards target 100=Target reached, -100=Stopped out
PositionEntry	Position Entry Price Avg
Volume	Volume of Bar
WarmupStatus	Current Warmup Status (between -100 and 100)

Type

Defines the type of display you would to use for this indicator.
The following types are available:

Bar	Vertical Bar (used mostly to display the Volume)
Candle	Only Price - display in Candlestick style
Dot	Displays a dot/circle at the value, no border is used
DotF, DotFrame	Displays a dot/circle at the value, the gird(black) border is used
HighLowBar	Only Price - display as High/Low Bar
Line	Continuous line
LineDot	Dotted line
LineRect	Small squares used to indicate the line
Rect, Square	Displays a square/rectangle at the value, no border is used
RectF, RectFrame, SquareF, SquareFrame	Displays a square/rectangle at the value, the gird(black) border is used
TxtDown	Show the centered text below the bar low ($Var has to be a text)
TxtUp	Show the centered text above the bar high ($Var has to be a text)

Color

Defines the color to be used for this overlay (default is black)
