Hey, I'm trying to trade using velocity/acceleration principles. 

I thought a good place to start would be by creating a momentum indicator into another, but for the life of me, I can't seem to do it.

Would anyone give me a hand please?

 

I've tried this ``` self.spyVelocity = self.MOMP("SPY", 10, Resolution.Minute) self.spyAcceleration = self.MOMP(10, Resolution.Minute) self.RegisterIndicator(self.spyVelocity, self.spyAcceleration, Resolution.Minute) ``` as well as this ``` self.spyVelocity = self.MOMP("SPY", 10, Resolution.Minute) self.spyAcceleration = IndicatorExtensions.Of(self.MOMP, self.spyVelocity) ```
