Hi,

I have a test csv file with signals for each day that I want to trade with. After using fetch csv and universe_func, I was able to get the symbols into my universe.

However, when I run the program, I get the runtime error 'SIDData' object has no attribute 'price'. I need the current price of the security for part of the algorithm.

I followed the example of using fetcher to create custom universe. Does anyone know what I am doing wrong?

import pandas as pd

pd.set_printoptions(max_columns=10)

def initialize(context):  
    # import the custom CSV data file  
    fetch_csv("https://dl.dropboxusercontent.com/s/jk2aldddnstbduy/analyst action spy trade may 2014.csv",  
              pre_func=preview,  
              post_func=preview,  
              date_column='date',  
              universe_func=my_universe)  
    context.max_notional = 1000000.1  
    context.min_notional = -1000000.0  
    context.istraded = {}  


# my_universe returns a set of securities that define your universe.  
def my_universe(context, fetcher_data):  
    # fetcher_data is the data resulting from the CSV file from fetcher.

    # set my_stocks to be every sid in the fetcher_data  
    my_stocks = set(fetcher_data['sid'])

    # log the size of the universe for debugging  
    context.count = len(my_stocks)  
    print 'total universe size: {c}'.format(c=context.count)

    # return the sids we identified earlier  
    return my_stocks

# see a snapshot of your CSV for debugging  
def preview(df):  
    log.info(' %s ' % df.head())  
    return df

def handle_data(context,data):  
    # Convert to EST timezone  
    exchange_time = pd.Timestamp(get_datetime()).tz_convert('US/Eastern')  

    # loop over the stocks in universe  
    for stock in data:  
        print stock.symbol  
        print data[stock].price
