I tried to use EDS cmd to query the end of day summary for all the future contracts in NYMEX, but I always got the 50007 error. What may I have done wrong? I posted my python code as following:

####################
import socket
IQ_PORT_LOOKUP = 9100
IQ_SEC_TYPE_FUTURE = 8
IQ_EXCHANGE_NYMEX = 36

def download_eod_summary(security_type, group_id, date, request_id=""):
host = "localhost"
port = IQ_PORT_LOOKUP
print('start sending cmd to {host},{port}')

# Establish a connection to IQFeed
with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
s.connect((host, port))

# Receive data until end message
with socket.socket(socket.AF_INET, socket.SOCK_STREAM) as s:
s.connect((host, port))
s.sendall(b'S,SET PROTOCOL,6.1\n')
#s.sendall(bytes('EDS,{security_type},{group_id},{date},' + str(request_id) + '\n', 'ascii'))
s.sendall(bytes('EDS,{security_type},{group_id},{date}' + '\r\n', 'ascii'))
f = s.makefile()
line = f.readline()
print("line="+repr(line))
while line.find('!ENDMSG!') < 0:
line = f.readline()
print("line=" + repr(line))
f.close()

download_eod_summary(security_type=IQ_SEC_TYPE_FUTURE, group_id=IQ_EXCHANGE_NYMEX, date="20240201")

The running debugging message is as following:

start sending cmd to {host},{port}
line='S,CURRENT PROTOCOL,6.1\n'
line='E,50007,No file available.\n'
line='!ENDMSG!,\n'

what could have gone wrong?

Do you have the "Globex Combo" subscription? If so, that doesn't include NYMEX.
