Michael,

Are you able to share the entire algorithm, or do you need to keep it private?

Grant

I'm unsure how to share it. I have no objection to doing so, though.

Just copy & paste the entire algorithm into the text editor like this (inside the "Code Sample - Ctrl+K" block):

algorithm goes here

It's aptly named

import random

# Put any initialization logic here.  The context object will be passed to  
# the other methods in your algorithm.  
def initialize(context):  
    pass

# Will be called on every trade event for the securities you specify.  
def handle_data(context, data):  
    # Implement your algorithm logic here.

    # data[sid(X)] holds the trade event data for that security.  
    # data.portfolio holds the current portfolio state.  
    # Place orders with the order(SID, amount) method.

    # TODO: implement your own logic here.  
    day = data[sid(24)].datetime.weekday()  
    if (day == 0):  
      order(data[sid(24)], 5)  
    if (day == 4):  
      order(data[sid(24)], -5)

Hi Michael,

Sorry you're having trouble, but I think I see the problem. The issue is the call to order. You want

order(sid(24), 5)  

The sid function returns a Security, which is the only thing order will accept. data[sid(24)] returns a SIDData object, which is a very simple object that holds all the current data for the security. Your code above is sending the SIDData object to the order method, and the system raises an exception.

Thanks for letting us know,

Grant, Thanks for jumping on the problem so quickly!

Fixed. Thanks
