There's several problems with your implementation:

1) each request is supposed to be followed by a carriage return and line
feed. This is \r\n, not \n.

2) sock.close should be sock.close()

3) after sending the headers, you have to send a blank line before
receiving data.

Given the changes mentioned above, the following works though the server
doesn't like the currency:

from socket import *
HOST = 'www.oanda.com'
PORT = 5011

sock = socket(AF_INET, SOCK_STREAM)
sock.connect(HOST, PORT)
sock.send('fxp/1.1\r\n')
sock.send('Query: quote\r\n')
sock.send('Quotecurrency: SFR\r\n')
sock.send('Basecurrency: EUR\r\n')
sock.send('\r\n')

print 'Response:'
while 1:
        data = sock.recv(1024)
        print data
        if not data: break
sock.close()
