My first Algorithm on Quantopian

posted Oct 25, 2017

Hi Quantopian Community,
I am a student and this is my first time on Quantopian. I was trying to build my first portfolio with 50% in a long position in FCAU and the rest cash. I wanted to have my position closed 30 minutes before the market close. What do you think? Any suggestion to improve it?

def initialize(context):  
    context.fcau = sid(47888)  
    schedule_function(open_positions, date_rules.week_start(), time_rules.market_open())  
    schedule_function(close_positions, date_rules.week_end(), time_rules.market_close(minutes=30))

def open_positions(context, data):  
    order_target_percent(context.fcau, 0.50)

def close_positions(context, data):  
    order_target_percent(context.fcau, 0)

I have another question:
Except the standard indicators (returns, alpha, beta etc) that the backtest shows me, what should I do if I want to add MACD, IV, P/E ratio and Aroon?

Thanks for the help,
Mattia

I put your code into a backtest and shared it here so people can evaluate it more easily.

To do further evaluations on your backtest, I suggest you load the data in research and start analyzing it there using the get_backtest command.

Edit: I forgot to mention, at this level of capital, your algorithm has a hard time getting in and out of such large trades.
