Hi,
My apologies I could't find a forum to post this question to.
I want to get a list of all trading pairs on Binance and then for each of these pairs I'd like to subscribe to get 3 min candlestick data (really just latest quote price)
Thanks, Jason
BinanceApiAsyncRestClientImpl.java
line 52 write a wrong method,equeue wrong to ‘equal()’
@Override public void getServerTime(BinanceApiCallback<ServerTime> callback) { binanceApiService.getServerTime().enqueue(new BinanceApiCallbackAdapter<>(callback)); }
According to https://github.com/binance-exchange/binance-official-api-docs/blob/master/rest-api.md#general-api-information HTTP 504 denotes an unknown state. Requests may have succeeded or failed.
How can one safely invoke https://github.com/binance-exchange/binance-official-api-docs/blob/master/rest-api.md#new-order--trade given that it may return HTTP 504 and we never get back a clientOrderId with which to query whether the order had actually succeeded?
I see that we can send clientOrderId into a request but the specification does not explain the format of legal IDs, nor what happens if the ID we send in is already taken. Are clientOrderIds unique per client? Or are they global IDs across the entire system?
So to reiterate the question: how can we safely create an order in a transactional fashion where we are guaranteed to know whether the order was successfully in the end?
I just want to buy 10 XVG, and it says "market is closed"
I have two users with api key and secret, I couldn't change the user because of this line:
BinanceApiServiceGenerator.java
private static OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
I changed this to:
public static <S> S createService(Class<S> serviceClass, String apiKey, String secret) {
OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
And now it is working!
I am getting a class cast exception when using the market ticker event stream.
Caused by: java.lang.ClassCastException: java.util.LinkedHashMap cannot be cast to com.binance.api.client.domain.event.AllMarketTickersEvent
Is anyone else having this issue? Code below for reference.
mWebSocketClient.onAllMarketTickersEvent(new BinanceApiCallback<List<AllMarketTickersEvent>>() {
@Override
public void onResponse(List<AllMarketTickersEvent> events) throws BinanceApiException {
Log.d(TAG, events.get(0).toString());
}
});
I made a buy on the binance web site
and I have a timer that is call
account.balances.forEach { balance ->
if (balance.free != "0.00000000") {
...
}
}
but this is not refreshing, how can I refresh my account and balances after a buy?
Hello @joaopsilva , experts.
I am looking for an approach to calculate the candlesticks for an interval less than 1sec which is not supported by binance API.
I don't know: maybe it is possible by mixing of agg trades and order book data that available from API?
Thanks a lot!
I run into this exception very often when using the web socket listeners. What is the correct way to deal with failing sockets? If I understand correctly there is no way to ignore the exception, but just accept the closure of the socket and ultimatively the thread.
But is there any smart way to restart the listener? I don't know which listeners closed. Do I need to resort to thread naming trickery and a thread watch dog?

The binance's trading rule only gives the min Amount of every coin, not give the min amount interval. Do someone know the min amount interval of every coin or where can I find it? Thanks a lot!
For example, the min amount for ETH/BTC is 0.001ETH, what about its min interval? still 0.001?
I want to sell/buy 0.363223 ETH in market price, but is says: "Numeric values only"
How can I do that?

Twice now I have received this StackOverflowError while doing normal trading. The Project is set up with a key and secret in live trading environment. Each time I was running a swing trading strategy on ONE_MINUTE intervals. It was executing a Buy when the error occurred. The first time it failed was after running for 128 minutes and the second time was after 162 minutes. Each of those windows contained numerous successful buy and sell trades. This was not caught and the whole program crashed. Any thoughts as to a patch the error so that the program will recover? You will notice the infinite loop being called into the following file. I have provide the full stacktrace of the StackOverflowError cutting off the part after where the pattern is oviously repeating. You will also notice the okhttp3 lib actually starts to repeat before the interceptor starts to loop with it.

When I invoke BinanceApiRestClient.getAllPrices() most of the tickers I get back are okay, but I am consistently getting back:
TickerPrice[symbol=123456,price=0.00030000]
which doesn't make any sense. Is this some sort of test data that someone forgot to remove?
I also see it if I request HTTP GET https://www.binance.com/api/v1/ticker/allPrices so this is affecting all clients.
like i pass order-id as parameter and get all Trades that are executed under this order.
currently GET /api/v3/myTrades (HMAC SHA256) not supporting this feature.
The binance API (https://www.binance.com/restapipub.html#user-content-account-endpoints) supports a newClientOrderId field that is A unique id for the order. Automatically generated if not sent. Can we add support for this?

Is it possible(with one api key and one api secret) to make a web socket stream for more than one cryptocurrency pair at the same time :?
I want to draw a chart from the last (24H or 1 week) lets say ethereum values
How can I do this with binance API?
Related code:
ObjectMapper is fairly expensive to create, and especially for Android, this can create quite the heavy pressure on the GC and memory usage, considering it is created on every socket message.
Therefore I kindly suggest to either:
BinanceApiWebSocketListener class constructor so we can allow more flexibility in creating ObjectMapper.ObjectMapper instance if it wasn't given and hold it locally as a private reference in a secondary constructor. This can maintain the current library compatibility.The same issue also present in UserDataUpdateEventDeserializer
I can help creating a pull request later to fix this, but if you guys have any other idea or other implementations in mind, then please feel free to share.
Excuse me but where can be found documentation about methods / interfaces and so on... :?
Hi,
thank you very much for sharing this good and usefull code.
I'have just started with java some months ago and i'm trying run some of the examples, everything goes well except for the classes where apikey and secret is needed. I'm filling the arguments apikey and secret with my numbers and after running I get this error:

Can you help me to find the reason?
Thank you!
The BinanceApiAsyncRestClient is useless if the caller of the async method isn't notified in case of error.
The BinanceApiCallback interface must have an onFailure() method so that the caller can be notified of errors.
val candlesticks = client.getCandlestickBars("NEOETH", CandlestickInterval.WEEKLY)
this is just gave me a crash, an Exception.. (maybe some json parse error /float to long?/)
client.onCandlestickEvent("ethbtc", CandlestickInterval.ONE_MINUTE) { response -> Logger.E(response) }
this is working like a charm, but when uses this
client.onCandlestickEvent("xvgeth", CandlestickInterval.ONE_MINUTE) { response -> Logger.E(response) }
the responses is not in 1 minutes, it is random minutes :( (from 1 minutes to 40 minutes, weird)
+1: how to stop the events?
我在LTCBTC市场当中，调用limitSell方法的时候，当quantity=0.943752像这个数字，就会报上面的错误（Filter failure: LOT_SIZE），但是我如果将quantity=0.2的这样的数字，就可以。那么的问题来了，我如何才能获取LTCBTC的配置呢，例如最小数量位数，最小数量，最小金额，最小金额位数呢？
I tried to run the example code provided in this library. When I run the AllMarketTickersExample.java class I get a bunch of exceptions and everything worked just fine before the Binance system upgrade. seems like it is something on their end, cause the same error pops up when trying to runt he other examples?
`public class AllMarketTickersExample {
public static void main(String[] args) {
BinanceApiClientFactory factory = BinanceApiClientFactory.newInstance();
BinanceApiWebSocketClient client = factory.newWebSocketClient();
client.onAllMarketTickersEvent(event -> {
System.out.println(event);
});
}
}`

I see roughly 30'ish instances currently of the use ToStringStyle.SHORT_PREFIX_STYLE used int the various toString() override implementations I'd like to override with ToStringStyle.JSON_STYLE.
example from CandlestickEvent.java
@Override
public String toString() {
return new ToStringBuilder(this, ToStringStyle.SHORT_PREFIX_STYLE)
.append("eventType", eventType)
.append("eventTime", eventTime)
.append("symbol", symbol)
...
.append("isBarFinal", isBarFinal)
.toString();
}
I like to use various JSON parsers such as google's GSON library to read and write the toString() outputs to file for logging or to be picked up by the database filereader. I might want to pass the JSON string via REST call to a web viewer as a JSON String. Also there are times when i want to pretty print them to console. i.e.
{
"symbol": "ETHUSDT",
"orderId": 12345678,
"clientOrderId": "smoD6joHgLUGlowNcZQcSf",
"transactTime": 1511234502823
}
If I currently pass the output in, its not in a standard JSON format and a malformed parser exception happens. I could create a data adapter to put it in a good JSON format but that fairly cumbersome for every object. I can just locally change the ToStringStyle.SHORT_PREFIX_STYLE to ToStringStyle.JSON_STYLE in every file that currently uses it but that would be difficult to maintain local dependency builds with updates upstream.
What I propose would be to have a non final, override-able constant in a Constants class. i.e.
public static ToStringStyle TO_STRING_BUILDER_STYLE = ToStringStyle.SHORT_PREFIX_STYLE; where the previous toString() example would refer to that constant. i.e.
@Override
public String toString() {
return new ToStringBuilder(this, TO_STRING_BUILDER_STYLE)
.append("eventType", eventType)
.append("eventTime", eventTime)
.append("symbol", symbol)
...
.append("isBarFinal", isBarFinal)
.toString();
}
where I could set it to ToStringStyle.JSON_STYLE if needed and this would not break backward compatibility if someone is expecting the toString() to be in SHORT_PREFIX_STYLE. Another option might be to start a user configuration file that sets this value or an initial programmatic binance-java-api configuration call where i could override the default setting for this value.
All in all i'd much rather use this library as a jar dependency without having to custom change and build it my self. Thought?
Just for fun, I'll provide my JSON pretty console print methods I have in a Utils class.
import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import com.google.gson.JsonElement;
import com.google.gson.JsonObject;

/**

*/
public static String toPrettyJsonFormat(String jsonString) {
String prettyJson = jsonString;
JsonParser parser = new JsonParser();
JsonElement jsonElement = parser.parse(jsonString);
if(jsonElement != null) {
JsonObject json = jsonElement.getAsJsonObject();
Gson gson = new GsonBuilder().setPrettyPrinting().create();
prettyJson = gson.toJson(json);
}
return prettyJson;
}

return toPrettyJsonFormat(String.valueOf(obj));
}

Hello. I'm trying to listen websocket notifications from binance by this simple code:
public class WebSocketReader implements Runnable {
private final String[] tickers;
private final BinanceApiWebSocketClient client = BinanceApiClientFactory
.newInstance().newWebSocketClient();
private BlockingQueue<DepthEvent> queue;
public WebSocketReader(String[] tickers, BlockingQueue<DepthEvent> queue) {
this.tickers = tickers;
this.queue = queue;
}
@Override
public void run() {
Arrays.stream(tickers).forEach(t -> client.onDepthEvent(t,
response -> {
queue.add(response);
}));
}
}
ExecutorService executor = Executors.newCachedThreadPool();
BlockingQueue<DepthEvent> queue = new ArrayBlockingQueue<DepthEvent>(10000, true);
executor.submit(new WebSocketReader(new String[]{"ethbtc"}, queue));
and this code throws exception on my mac and works nice on linux:

Hi, I am using the provided example (UserDtaStremExample) to listen to order statuses for a specific user. But when I open a user data stream I can only get order statuses for a few minutes, then it stops reporting orders. According to binance documentation the user data stream should remain open for 60 minutes unless a keep alive message is sent. I experimented sending keep alive requests every 2 minutes but I still get the same problem.
Looking at https://github.com/binance-exchange/binance-official-api-docs/blob/master/web-socket-streams.md which your API mirrors,
What is the meaning of "Is the buyer the market maker?" I understand the concept of a maker vs taker, but what is the meaning of "the market maker" and what does this change for us if the value is true?
How can an aggregated trade event contain a single price/quantity value when it spans multiple trades? Are the trades guaranteed to be at the same price? Similarly, how can you only have a single trade-time across multiple trades?
Can we get this added to maven repository?

Hello,
in my App I want to calculate a Dollar-price for every coin by getting all trading pairs and matching them up.
Let's say I want to get the worth of IOTA in dollar. I get IOTA/ETH and continue to get ETH/USD. Now I can calculate IOTA/USD and display it.
The problem is this:
Calling getAllPrices() results in symbols like ETHBTC, WAVESBTC or NEBLBTC.
There is no indicator where to split the two coins. Since symbols can be different length, I can't just split them in the center.
How can I split them correctly?
When using the getDepositAddress function, I get "api not exist". Does Binance support this function?
The version number used for this project is set for a release version, but a number of code changes have been made under the same released version number.
Ideally a single commit should be considered the "released" version whenever you feel is apt, and all in between development versions should be labeled snapshot. The way it is now, it would not play nice with a Maven Repo.
The change I would suggest it to make the version 1.0.1-SNAPSHOT, where the snapshot qualifier is used to indicate it is a development build. This version scheme works properly with the various Maven Repositories I have used.
If you want to read up a bit more on Maven's number scheme, you can see it here:

Hi everyone,
I am trying make an android app that uses this library. I compiled .jar file and successfully added to my android studio project.
My problem is that on some devices, when I try to make an API call, an exception like above had been throwed. Same code working on some emulator, not working on physical devices.
Any ideas? Thanks.
Excuse me but which library exactly should be installed ? Thanks !
