Financial Charting. TeeChart Pro has always been at the cutting edge of Financial Charting and the ActiveX v6 makes this very clear; with three distinct financial series and fourteen dedicated financial functions it is one of the most flexible Financial Charting tools on the market. Financial Series and Functions A selection of these can be visualised here: Specifically, the TeeChart Pro v6 ActiveX Control consists of the following financial features: Financial Series: Candle (OHLC) Series, with subtypes: Normal, Bar, No Open, No Close, No Border and Line Volume Series, with subtypes: Normal, Dotted, Colors and Origin Point and Figure Series Financial Functions (all with subtypes: Normal, Stairs, Points, Height, Hollow, Colors, Marks, No Border except where indicated): ADX RSI Moving Average Exponential Moving Average Momentum MACD Stochastic Bollinger Bands Compression, with subtypes Normal, Bar, No Open, No Close, No Border, Line Close Location Value On Balanced Volume Commodity Channel Index Volume Oscillator All of these Series and Functions can be added to your Chart at design time; simply right-click over an embedded TeeChart ActiveX Object (on a VB.NET WinForm, for example) and select?edit?" and then hit the?add?" button. Selecting the Series tab and the Financial sub-tab and clicking on the bottom-left of the Candle series will give you the following:

2 Moving over to the Functions tab and again selecting the Financial sub-tab will give you:

3 Adding Data to the Financial Series Let?s assume that the data needed to be represented is in a database, one of a number of possible scenarios which can be coded along the same general principles. Let?s have a look at some VB6.0 code that connects a Candle Series with the Stocks table of the TeeChart Pro Database, a database that is installed by default with the TeeChart Pro v6 ActiveX Control licensed and evaluation versions. With a TeeChart Pro v6 ActiveX Object and a CheckBox on the VB6.0 Form (make sure you have referenced the?microsoft ActiveX Data Objects 2.8 Library" from Project -> References?), paste in the following code: Option Explicit Dim Conn As ADODB.Connection Dim rst As ADODB.Recordset Private Sub AddAsDatetime() With TChart1.RemoveAllSeries.AddSeries sccandle With.Series(0).DataSource = rst.ascandle.openvalues.valuesource = "Open".asCandle.HighValues.ValueSource ="High".asCandle.LowValues.ValueSource = "Low".asCandle.CloseValues.ValueSource = "Close".LabelsSource = "Date" Private Sub AddAsNoWeekend() Dim Count As Integer With TChart1.RemoveAllSeries.AddSeries sccandle With rst.movefirst While Not.EOF If Weekday(.Fields("Date")) <> 1 And Weekday(.Fields("Date")) <> 7 Then TChart1.Series(0).asCandle.AddCandle Count,.Fields("Open"),.Fields("High"),.Fields("Low"),.Fields("Close") TChart1.Series(0).PointLabel(Count) =.Fields("Date") Count = Count + 1 End If.MoveNext Wend Private Sub Check1_Click() If Check1.Value = 1 Then AddAsNoWeekend Else

AddAsDatetime End If Private Sub Form_Load() Set Conn = CreateObject("ADODB.Connection") Set rst = CreateObject("ADODB.Recordset") Conn.Open "DSN=TeeChart Pro Database" rst.

4 AddAsDatetime End If Private Sub Form_Load() Set Conn = CreateObject("ADODB.Connection") Set rst = CreateObject("ADODB.Recordset") Conn.Open "DSN=TeeChart Pro Database" rst.open "select * from stock", Conn, 1, 1 TChart1.Axis.Bottom.Labels.Angle = 90 Check1.Caption = "Add without weekends" Check1.Value = 1 Private Sub Form_Unload(Cancel As Integer) rst.close Conn.Close Running the above code will give you the following two images, one with and one without the CheckBox checked:

As you can see from this code, avoiding the representation of weekend days in the Candle Series simply involves iterating through the dataset and only adding in the week days, setting the dates on

5 As you can see from this code, avoiding the representation of weekend days in the Candle Series simply involves iterating through the dataset and only adding in the week days, setting the dates on the bottom axis with the ISeries.PointLabel method. Associating a Financial Function with a Financial Series Performing this operation is a simple task both at designtime and runtime. At runtime, using the VB6.0 example described above, we could simply add a CommandButton to our VB6.0 Form and paste in the following code: Private Sub Command1_Click() With TChart1.AddSeries scfastline.series(1).setfunction tfbollinger.series(1).datasource =.Series(0).Series(1).FunctionType.asBollinger.LowBand.Color = vbcyan.series(1).color = vbcyan.series(1).functiontype.asbollinger.deviation = 3.Series(1).FunctionType.asBollinger.Exponential = False.Series(1).FunctionType.PeriodAlign = palast.series(1).functiontype.periodstyle = psnumpoints.series(1).functiontype.period = 2.Series(1).CheckDataSource This will associate a Cyan coloured Bollinger Band function with the database-connected Candle Series as can be seen in the following image:

6 Of course, you may not wish the function to share the same axes as the original Candle Series, in which case you may consider the use of Custom Axes, an example of which can be found in both licensed and evaluation versions under: Examples/Visual%20Basic/Visual%20Basic%205%20%26%206/Multiple%20Axes/
