BloodHound Simple Strategy Example 1


Overview


Note:
You must have ‘Developer Extensions’ checked when you ran the SharkIndicators Installer.   That will also install the example code file.

This example file is included in the ‘Developer Extensions’ and can be found in the ‘MyDocuments\NinjaTrader 8\bin\Custom\Strategies’ folder as ‘SiBloodHoundStrategExample.cs’.  For NT 7, see the Downloads section below.  You can safely delete this file when you are done with it.

This example illustrates the bare minimum BloodHound strategy implementation.  It mimics the functionality already accomplished by the base class SiBloodHoundStrategy but overrides the OnBarUpdate method which can be extended with your code.

Entry signals are taken when BloodHound has a signal in that direction.  This is governed  by the active logic template.

Discussion


To begin with a BloodHound strategy, derive your Strategy class with SiBloodHoundStrategy instead of the usual Strategy class as illustrated in line 8 above.

Also note that if you override the OnStateChange() method, you must call thebase.OnStateChange(); method as shown on line 45.

Finally you can see that the entry code uses the BloodHound indicator on line 80 and 90. BloodHound is an accessible property from the SiBloodHoundStrategy class, and LongSignals and ShortSignals are Series<bool> representing signals computed from BloodHound.
