I'm writing my own first algo on the platform. I am having trouble subscribing. # Subscribe and set our expiry filter for the futures chain
future5yrNote = self.AddFuture(Futures.Financials.Y5TreasuryNote)
future10yrNote = self.AddFuture(Futures.Financials.Y10TreasuryNote)

# Set our expiry filter to return all contracts expiring within 90 days
self.future5yrNote.SetFilter(0,90)
self.future10yrNote.SetFilter(0,90)

# Data resolution
self.UniverseSettings.Resolution = Resolution.Tick
During the algorithm initialization, the following exception has occurred: AttributeError : 'FYNcurveSpread' object has no attribute 'future5yrNote'
at Initialize in main.py:line 26
AttributeError : 'FYNcurveSpread' object has no attribute 'future5yrNote'Seems easy, just can't find the attribute name for that futures chain.?
