Help for my first algorithm !

Hi, I'm new in this community and I'm having problems in writing my first code. I have very little coding skills, most of it in VBA, so I will appreciate if someone can help me finish this.

This is the code:

def initialize(context):
context.security=sid(8554)

def handle_data(context, data):
for position in context:
s1 = 2*data[context.security].vwap(5)
l1 = data[context.security].vwap(10)
s2 = 2*data[context.security].vwap(6)-data[context.security].vwap(1)
l2 = data[context.security].vwap(11)-data[context.security].vwap(1)
total1= (s1-l1)
total2= (s2-l2)

if total1 > total2:
order(context.security,+100)

elif total1<total2:
order(context.security,-100)

I really don't know where is the problem.
Thanks for your help!

Hi Facundo,

Welcome to Quantopian! The problem is with the line for position in context:. Getting rid of this line entirely should solve your problem. However, if you wanted to change this to trade multiple stocks, you will want to look at each security in data (as opposed to in context). I've attached a backtest with that change in it. Take a look at this tutorial video for a quick demo!
