Market Data Subscription Push

Subscribe to Stock Quotes

subscribeQuote(Set<String> symbols)

Cancellation Method

cancelSubscribeQuote(Set<String> symbols)

Description

Subscribe to real-time stock quote updates.
Updates are asynchronous. Implement ApiComposeCallback to receive QuoteBasicData and best bid/offer QuoteBBOData objects.

Input Parameters

Parameter	Type	Required	Description
symbols	Set<String>	Yes	Stock symbol list, stock symbol format: e.g., `AAPL`, `00700`

Response

Field	Type	Description
id	string	ID generated locally by the SDK when making a subscription request, incrementally sequential. Returns the request ID and subscription success result in the `subscribeEnd(int id, String subject, String result)` callback method

Callback Interfaces

void quoteChange(QuoteBasicData data)
void quoteAskBidChange(QuoteBBOData data)

Example

Define callback interfaces. After successful subscription, data will be received in the corresponding interfaces of this callback class.

Subscribe to Option Popular Trading Rankings

subscribeOptionTop(Market market, Set<Indicator> indicators)

Cancel Method

cancelSubscribeOptionTop(Market market, Set<Indicator> indicators)

Description

Subscribe to option rankings. During trading hours, the server sends the top 50 symbols for each subscribed indicator every 30 seconds. It does not send updates outside trading hours.
Updates are asynchronous. Implement ApiComposeCallback to receive OptionTopData objects. A big order is a single trade with volume greater than 1,000; big orders are sorted by trade time in descending order. Other indicators are cumulative values for the trading day, sorted in descending order.

Supports ranking indicators for US options. During trading hours, updates include every indicator in OptionRankingIndicator.

Request Parameters

Parameter	Type	Required	Description
market	Market	Yes	Market, supports US
indicators	`Set<Indicator>`	No	Option ranking indicators, defaults to all indicators, refer to OptionRankingIndicator enum values (bigOrder: big orders, volume: daily cumulative volume, amount: daily cumulative turnover amount, openInt: open interest)

Response

Field	Type	Description
id	string	ID generated locally by SDK subscription request, incrementally sequenced. Returns request ID and subscription success result in `subscribeEnd(int id, String subject, String result)` callback method

Subscription Example

Market market = Market.US;
Set<Indicator> indicators = new HashSet<>();
indicators.add(OptionRankingIndicator.Amount);
indicators.add(OptionRankingIndicator.OpenInt);
//Subscribe to all indicators for the market
client.subscribeOptionTop(market, null);

//Wait to receive the data
TimeUnit.SECONDS.sleep(120000);
// Cancel subscription of 'amount' and 'openInt'
client.cancelSubscribeOptionTop(market, indicators);
// Cancel all indicators' subscription
client.cancelSubscribeOptionTop(market, null);
