So I want to make trades based on the slope of the volume of shares being traded. It looks great in TradingView but I am now attempting to bring it on to QuantConnect. The tickers are of course fillers but I will happily share them once someone helps me lol

class VentralParticlePrism(QCAlgorithm):

def Initialize(self):
self.SetStartDate(2012, 7, 17) # Set Start Date
self.SetEndDate(2020, 7, 17)
self.SetCash(250000000) # Set Strategy Cash
self.AddEquity("SPY", Resolution.Minute)
self.AddEquity("XYZ", Resolution.Minute)
self.AddEquity("ABC", Resolution.Minute)
self.vma = self.SMA("ABC", 365, Resolution.Daily, Field.Volume)
#Here is my problem.
self.vmaSlope = self.MOMP(self.vma, 14, Resolution.Daily)
#How do I calculate this? I want to find the momentum of this indicator over the given period.

def Derp(self):
if self.vmaSlope <= -0.1:
self.SetHoldings("XYZ", 0.9)
self.SetHoldings("SPY", 0)
self.SetHoldings("ABC", 0.1)
if self.vmaSlope.Current.Value <= -0.01:
