I am not sure if I understand what QC paper trading platform is.  Is this QC platform linked to a real broker demo account? 

Also, is the following strategy/algorithm lifecycle correct?

  1. Strategy development (e.g. in Python)
  2. Strategy backtesting
  3. QC paper trading testing
  4. IB paper trading testing (or other partner broker)
  5. Live trading on IB live account (or other partner broker).
