I need to create a real-time algorithmic trading system (Stocks and Forex), fully automated connected to an account at an online broker .
I want it to be coded in Python.

• I want all trades positions to be closed at the end of the day. NO overnight position
• Trading only during regular trading hours in the US market to start (NYSE, NASDAQ), eventually Europeans markets
• First, I want to back test the system then paper trading environment and eventually go live.
