query_subscription(is_all_conn=True)
Description
Get subscription information
Parameters
Parameter Type Description is_all_conn bool Whether to return the subscription status of all connections. True: return the subscription status of all connections.
False: return only the status of the current connection.
Return
Field Type Description ret RET_CODE Interface result. data dict If ret == RET_OK, subscription information data is returned. str If ret != RET_OK, error description is returned. subscription information data format as follows:
{ 'total_used': subscription quota used by all connections, 'own_used': The subscription quota used by the current connection, 'remain': remaining subscription quota, 'sub_list': The stock list corresponding to each subscription type, { 'Subscription type': A list of all subscribed stocks under this subscription type, … } }
Example
from futu import *
quote_ctx = OpenQuoteContext(host='127.0.0.1', port=11111)
quote_ctx.subscribe(['HK.00700'], [SubType.QUOTE])
ret, data = quote_ctx.query_subscription()
if ret == RET_OK:
print(data)
else:
print('error:', data)
quote_ctx.close() # After using the connection, remember to close it to prevent the number of connections from running out

query_subscription(is_all_conn=True)
Description
Get subscription information
Parameters
Parameter Type Description is_all_conn bool Whether to return the subscription status of all connections. True: return the subscription status of all connections.
False: return only the status of the current connection.
Return
Field Type Description ret RET_CODE Interface result. data dict If ret == RET_OK, subscription information data is returned. str If ret != RET_OK, error description is returned. subscription information data format as follows:
{ 'total_used': subscription quota used by all connections, 'own_used': The subscription quota used by the current connection, 'remain': remaining subscription quota, 'sub_list': The stock list corresponding to each subscription type, { 'Subscription type': A list of all subscribed stocks under this subscription type, … } }
Example
from moomoo import *
quote_ctx = OpenQuoteContext(host='127.0.0.1', port=11111)
quote_ctx.subscribe(['HK.00700'], [SubType.QUOTE])
ret, data = quote_ctx.query_subscription()
if ret == RET_OK:
print(data)
else:
print('error:', data)
quote_ctx.close() # After using the connection, remember to close it to prevent the number of connections from running out
