Ant: Simulating volume profile in Activity Bar?

[nasdaq5048 10]

Ant,

 

I am trying to figure out a way to simulate a volume profile in activity bar. I figure using a 1 min interval in the activity bar gives a fairly good representation of the volume profile and it requires less calculation than using marketprofileplus on a one minute bar (See figure 1).

 

The activity bar can calculate the value area with the function AB_SetZone. Although it doesnt seem as accurate as yours, but for a rough estimate, it is good enough. I try to paint the value area using the ZoneHi and ZoneLo in the activity bar code and added the follwoing line to the default price distribution indicator

 

Value2 = AB_AddCellRange( zonehi, zonelo, RightSide,

CellGroupLabel, red, 0 ) ;

 

and came up with a painted area that doesnt fit within the value area bracket. (See Figure 2).

 

 

What lines can i add to just tell tradestation to paint the bars within the zonehi and zonelo in a different color?

 

Thank you in advance for your advice.

Hello Nasdaq5048,

 

I would be happy to see what I could do if you want to send me your analysis technique.

Hi,

 

Here it is:

 

{ This study plots the basic ActivityBar, together with a value area zone based on

standard deviations around the ActivityBar's mode price. }

 

inputs:

ApproxNumRows( 10 ), { approx number of rows in each activity bar }

CycleColors( true ), { The CycleColors input determines whether the color of

cells is varied from one cell group to the next. This input has effect only

when this study is applied to chart in which Data1 is daily or minute bars and

when the hidden ActivityData is in minute bars. In all other cases, CycleColors

is ignored - the cells are drawn in the color specified by the DefaultColor

input. }

DefaultColor( DarkGreen ),

ModeType( -1 ), { 1= highest mode, -1 = lowest mode - see inline documentation in

function AB_Mode for more information on this input }

ZoneNumDevs( 1 ) ; { number of std devs on each side of mode price to be included

in the AB Zone }

 

variables:

CellGroupColor( 0 ),

MinuteInterval( BarInterval of ActivityData ),

CellGroupLabel( "" ),

oModeCount( 0 ),

oModePrice( 0 ),

SDev( 0 ),

ZoneHi( 0 ),

ZoneLo( 0 ) ;

 

AB_SetRowHeight( AB_RowHeightCalc( ApproxNumRows, 3 ) ) ;

 

if CycleColors then

CellGroupColor = AB_NextColor( MinuteInterval ) of ActivityData

else

CellGroupColor = DefaultColor ;

 

if CellGroupColor = GetBackGroundColor then

CellGroupColor = DefaultColor ;

 

CellGroupLabel = AB_NextLabel( MinuteInterval ) of ActivityData ;

 

Value1 = AB_AddCellRange( High of ActivityData, Low of ActivityData, RightSide,

CellGroupLabel, CellGroupColor, 0 ) ;

 

Value2 = AB_Mode( RightSide, ModeType, oModeCount, oModePrice ) ;

SDev = AB_StdDev( ZoneNumDevs, RightSide ) ;

ZoneHi = MinList( High, oModePrice + SDev ) ;

if ZoneHi = 0 then { ie, if oModePrice + SDev = 0 }

ZoneHi = High ;

ZoneLo = MaxList( Low, oModePrice - SDev ) ;

{ if oModePrice - SDev = 0 then ZoneLo = Low, so don't need a check here }

 

AB_SetZone( ZoneHi, ZoneLo, RightSide ) ;

 

 

Value2 = AB_AddCellRange( zonehi, zonelo, RightSide,

CellGroupLabel, red, 0 ) ;

 

 

I just added the last line to the default price distribution. Can you figure out a way to get it to plot the color between zonehi and zonelo?

I don't have it working yet. I will be away about a week. If I get something working, I will post it here, but it will be after this week.

Here is the theard i started on TS. Looks like it is getting closer of being done.
