I have a strategy backtested in my own system. I am thinking of using quantconnect to do paper trading and then to trade it live. I will submit the names through my system to quantconnect and participate on market on close. Its a stock selection model doing long and short. 

Do you know how to do it in the fastest way?

You may suggest to use a broker directly, but through quantconnect, I can let people see my strategy performance and they can seed it. 

Thank you
