ChartProfilesModel

ChartProfilesModel manages the collection of volume profiles for a chart indicator. It controls when new profiles are created through creation mode delegates. StackedProfileModel extends it for stacked (overlapping) profiles.

Namespace: MZpack Inheritance: ChartProfilesModel : Model | StackedProfileModel : ChartProfilesModel Source: MZpackBase/mzVolumeProfile/ChartProfilesModel.cs, MZpackBase/mzVolumeProfile/StackedProfileModel.cs

warning

Do not modify ChartProfilesModel directly — use the indicator interface (IVolumeProfileIndicator) to read and manage profiles.

Properties

Property	Type	Description
Profiles	List<IModelItem2>	All profiles in the model
Slot	int	Profile slot index
TicksPerLevel	int	Level aggregation
ProfileType	ProfileType	Display type: TPO, VP, VP_TPO, None
Creation	ProfileCreation	Creation mode
CreationValue	int	Threshold for the creation mode
VWAPMode	VWAPMode	VWAP calculation mode
HasTPO	bool	Whether TPO data is being calculated
HasVP	bool	Whether volume profile data is being calculated

Creation Delegates

The model uses two delegates to determine when to create a new profile:

• IsAddModelItemOnDataItemDelegate — evaluated per bar; returns true to start a new profile
• IsAddModelItemOnDataEventDelegate — evaluated per market data event; returns true to start a new profile

The active delegate depends on the ProfileCreation mode. Time-based modes (Session, Daily, Weekly) use the data item delegate. Volume-based modes (Volume, Delta, Tick) use the data event delegate.

ProfileCreation Enum

Controls how profiles are segmented. Set via IVolumeProfileIndicator.ProfileCreation.

Value	Description
Custom	User-defined profile boundaries
Composite	Composite profile across the entire chart
Continuous	Single continuous profile that grows indefinitely
Session	One profile per trading session
Sessions	One profile per N sessions
Bar	One profile per bar
Bars	One profile per N bars
Daily	One profile per day
Days	One profile per N days
Weekly	One profile per week
Weeks	One profile per N weeks
Monthly	One profile per month
Months	One profile per N months
Quarterly	One profile per quarter
Yearly	One profile per year
Volume	New profile when total volume reaches threshold
Delta	New profile when absolute delta reaches threshold
Tick	New profile when tick count reaches threshold
RTH_ETH	Separate profiles for Regular and Extended Trading Hours
None	No automatic profile creation

StackedProfileModel

StackedProfileModel extends ChartProfilesModel to support up to 3 overlapping profiles on the same chart. Each stacked profile has independent creation settings.

Property	Type	Description
StackedProfile	IModelItem2	The current stacked profile
Ago	int	Profile offset (0 = current)
LastN	int	Number of historical profiles to keep
