BloodHound Simple Strategy Example 2

Please note, SharkIndicators does not provide any NinjaScript, programming, or coding support.
This information is provided as-is and for knowledgeable programmers.

Overview

Note:
You must have ‘Developer Extensions’ checked when you ran the SharkIndicators Installer.  That will also install the example code file.
This example illustrates how to use multiple BloodHound logic templates within your strategy. This can be useful if you find the need to utilize BloodHound’s logic capabilities for different purposes.

In this example, we use a logic template for the entries, and another logic template for the exits. We allow the user to select which template to use for each case.

Discussion

Firstl, be sure to derive your class from the 'SiBloodHoundStrategy' class as in line 22.  In this example, notice that 2 public properties have been declared for the user to select logic templates: EntryLogicTemplate, and ExitLogicTemplate. They are declared as integers (int) and use the BloodHoundLogicDropDownSelectorTypeConverter2 as seen on lines 31 and 52.

Note:
BloodHoundLogicDropDownSelectorTypeConverter2 counterpart BloodHoundLogicDropDownSelectorTypeConverter is designed for WinForms classic property grid, whereas BloodHoundLogicDropDownSelectorTypeConverter2 is designed for the WPFPropertyGrid

Finally the entry and exit logic values are retrieved from BloodHound using the GetLogicSignalValue() method, using the logic templates identified by EntryLogicTemplate and ExitLogicTemplate as seen on lines 131, 142, 160 and 172.
