When switching to Live paper trading, I am wondering about the execution timing and order of the portfolio. In my backtest all works fine but in Live/paper the trades are not executed.

I read through the Live trading documentantion but still had two questions:

1. Is it fair to say that Universe Selection is automatically executed between 4-7AM ET each day? Are the AlphaModel, PortfolioConstruction and ExecutionModel then executed sequentially after the universe selection has been completed or is a scheduled event required to construct the portfolio?

2. In addition as of what time in the evening are the close prices available for extended market hours?


class TestAlgo(QCAlgorithm):

def Initialize(self):
# initialize all parameters
# ....
self.UniverseSettings.Resolution = Resolution.Daily

# Leverage Algo framework for execution
self.SetUniverseSelection(MyUniverseModel()) # Leverages coarse and fine of FundamentalUniverseSelectionModel

def OnData(self):
# leverage algo framework instead of OnData
