# Subscribe Quote
#
# To subscribe quotes data, please check whether "Developers" - "Quote authority" is correct.
# https://open.longportapp.com/account
#
# - HK Market - BMP basic quotation is unable to subscribe with WebSocket as it has no real-time quote push.
# - US Market - LV1 Nasdaq Basic (Only OpenAPI).
#
# Before running, please visit the "Developers" to ensure that the account has the correct quotes authority.
# If you do not have the quotes authority, you can enter "Me - My Quotes - Store" to purchase the authority through the "LongPort" mobile app.
