.account doesn't do anything anymore, not even an error.

Need to figure out how to do this, which indications are given by ws that there's been a connection error. A number of the routes push data every second. Should be possible to attempt a reconnect if nothing is received for X amount of seconds. Maybe have incremental back off on the reconnects. More info/inspiration here: issc29@76bfeaf

There is already a question about this here... But I still couldn't get my head around it.

My observation:

maker: true // The trade should be marked RED ?
maker: false // The trade should be marked GREEN ?
isBuyerMaker: true // I don't know what this is or what it's used for ?

I just found contradictory information about it, please someone clarify.

I mean what should it mean "IS BUYER MAKER" ? What I buy my own order ?
I buy what I made? What kind of vocabulary is this?

I try to use https://api.binance.com/api/v3/ticker/price but it retrieve all tickers at once, i need just BTC pair prices.

How can I solve this issue for streaming the API and it is also doing same for REST API?

No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:3000' is therefore not allowed access. The response had HTTP status code 400. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

I would like to retrieve all my past trades, but I don't remember all the symbols I have traded with. Right now it's not possible to get all my trades without passing a symbol, so to do that I have to get all the available symbols in Binance and then loop through and make a request to myTrades for each symbol. Besides making too many requests, many of them return of course an empty response.

Do you plan to fix this anytime soon?

Thanks

Hello! Loving this implementation so far! I've been playing with the user data websocket and I've noticed that after 1 hour of inactivity it closes with code 1006. This is the full object passed through the onclose event of the socket:

{
	"target": {
		"domain": null,
		"_events": {
			"error": [null, null, null],
			"close": [null, null]
		},
		"_eventsCount": 3,
		"readyState": 3,
		"bytesReceived": 87667,
		"extensions": {},
		"protocol": "",

		"_req": null
	},
	"type": "close",
	"wasClean": false,
	"reason": "",
	"code": 1006
}

I've reduced the keep alive timer to 30000 ms, in case that may be a factor, but it doesn't seem related as the timing remains 1 hour after the last activity. Hope the onclose event object is useful in diagnosing this. This is with the latest version (1.3.3).

I may be missing something here, but is there no way to do the following?

const ws = new Binance.BinanceWS

...

// Manually close the socket
ws.close()

Hello! I'm trying to set up websockets to monitor order books (depth = 10) and this error keeps killing my code:

Error: Unexpected server response: 504

Occasionally it's 502, as well.

Is there a way to catch the error in my code? I don't see an onError event or anything. I tried putting the .onDepthLevelUpdate function in a try/catch block, to no avail.

Thanks!
Jason

Editing to add some additional detail: It's intermittent (as expected from 502/504 errors) but typically happens ~20-30 seconds after I start the sockets.

I've made a bug related to this in electron-compile: #286

Below is the same thing I put in that issue.

I've run into a situation where when I do two simultaneous rest calls from the binance package I shortly after encounter a crash.

Is openTime the same as startTime? If so, does the same also apply to closeTime & endTime?

https://github.com/aarongarvey/binance/blob/master/lib/beautifier.js#L18
https://github.com/aarongarvey/binance/blob/master/lib/beautifier.js#L75

What are your thoughts in normalising the differences in both beautifier sections for consistency, if they are indeed the same? It's less overhead for developers looking to combine both websocket and historic data. Right now I'm assuming they are the same, and simply changing the var in the response before passing it to the DB.

There's also these:

• quoteAssetVolume & quoteVolume
• volumeActive & quoteVolumeActive & takerBaseAssetVolume & takerQuoteAssetVolume

I assume the latter are related but I'm not sure. Thanks!

I've been running Gekko with Binance v1.3.1

Hi.
After discussion with Binance people on Slack, I noticed that API https://www.binance.com/api/v1/ticker/allBookTickers can be used to retrieve all tickers (hence all existing pairs). Do you think it could be a nice addition to your wrapper ?
Thanks
Regards

Am I correct to infer that a trade with isBuyerMaker = true implies that this trade was completed by a sell?
I.e.: a buyer added an order to the depthbook and this trade is completed by a taker of said order (implying a sell)

Similarly, does aggTrade.maker= true imply this aggtrade is completed by a sell?

I don't know if this is the right place to ask, in case it's not just close the ticket.

What I'm trying to understand is what happens when I cancel a partially filled order.
Let me explain: I know that a part of the order is bought and another part is cancelled but I'm wondering if the order status will still be PARTIALLY_FILLED or it becomes CANCELED and how to handle that case.

Thanks!

Hey, as usual I was trying out this wrapper, and before reading the documentation, my blind guess for (eg:) allOrders method was this;

binanceRest.allOrders('BNBBTC', (data) => {
        console.log(data);
});

Which does not work should have had error as first parameter, having the "error" as the first parameter looked kinda weird, wanted to give feedback about it. What about swapping them, or having an error message of "No error" in order to lead the developers blindly guessing, because in my example all I see in the console is "null" string.

Thank you for the wrapper by the way!

bestBidPrice is called bestBid.

This is inconsistent with bestAskPrice defining the bestAskPrice in beautify.

when i run the demo follow the README
`node_modules/binance/lib/rest.js:8

Problem:
Because of CORS and Binance's server config, a server is currently required for accessing any endpoint. While this makes total sense for signed endpoints, its a bit overkill for unsigned endpoints (allPrices, etc).

Solution:
I see that you guys are running on nginx. You can allow cross origin requests for specific endpoints:

location /api/v1/ticker/allPrices {
        add_header 'Access-Control-Allow-Origin' '*';
}

This will allow people to contribute much simpler apps, widgets, etc. without having to spin up a server instance 🤘🏻

This is how we get current prices

https://api.binance.com/api/v1/ticker/allPrices

Can we get the historical prices?

got error from the console.

Even after closing the onUserData websocket , a keepAlive request is still sent by the setInterval function inside this api.

Can someone please explain how to properly close this. Thanks.

Here is a demo code -

binanceWS.onUserData(binanceRest, (data) => {
    console.log(data)
},60000) // Optional, how often the keep alive should be sent in milliseconds 
.then((ws1) => {
    // websocket instance available here
    console.log(ws1)
});

//Close this socket after 10 secs
setTimeout(function deleteUserStream(){    
    binanceRest.closeUserDataStream({
        listenKey:'/////listen key/////'
    })
    .then((r3) => {
       //ws.close();
       console.log(r3);
    })
    .catch((err) => {
        console.error(err);
    });
},10*1000);

Could you please help me to understand how to track order updates and status?
Or at least what to use or where to look at?

what should I use if I need to track all updates continuously?

I tried to find something in docs, but didn't succeed. Please help

I wonder about the interest to simplify this library with functional style.

Here is essentially complete implementation for the websocket part, without beautifier
(which would be a composition with another transformer):

const { map, curry, pipe, compose } = require('ramda')
const BASE_URL = 'wss://stream.binance.com:9443/ws/'

// the url getter is independent of the rest of the code
const getUrl = (type, symbol) => [
  BASE_URL, 
  symbol.toLowerCase(),
  `@`,
  type
].join('')

// general purpose websocket factory
const WebSocket = require('ws')
const createWS = path => cb => 
  new WebSocket(path).on('message', cb)

// Functor structure on the CPS (continuation-passing-style) functions
const cpsMap = f => cpsFn => 
  // new CPS function
  cb => cpsFn(compose(cb, f))

// Final WS stream from Binance as functional composition
const getStream = pipe
(
  getUrl
, createWS // returns f: cb -> void
// apply map from the CPS functor
, cpsMap(JSON.parse)
)

// start WS stream and pass the callback
getStream('trade', 'BNBBTC')(console.log)

in klines, quotevolumeactive represents what?

tks!

Currently, for the Kline/Candlestick data websocket, these params are not supported.
It'd be great if these could be added! 😄

I thought it was plain JavaScript which I can simply link and use.

1. Installed Node
2. cd binance-master
3. npm install

I have never used node but I am good with JavaScript. Can you list down in few steps that how to use/run this?

Hi,

I first create a call to check /api/v1/ticker/24hr and then try to issue a buy but I get the following error.

buyObj { symbol: 'APPCBTC', side: 'BUY', type: 'LIMIT', timeInForce: 'IOC', quantity: '4.40760', price: 0.00018150460000000002, timestamp: 1515391995190 }

ERR in buy {"code":-1111,"msg":"Precision is over the maximum defined for this asset."} :: { BINANCE }

What do I need to adjust to have this work?

Thank you

Specifically needs the BinanceWS object and methods. Should likely accompany the work for 2.0 that changes the class.

Modify lib/rest.js file, and add the following code.
Then it is configable to proxy.
This is for some special countryies.

I'm trying to get the quantity and price to place an order but I'm failing miserably. Math is really not my thing...
I have the exchange Info with the filters for each pair... whatt i want to achieve in this particular order (although I'd like a universal solution) is to get balance from btc, place order with that amount. then get balance of bought asset and sell that amount.

the problem is I'm failing to get the right amount to place the order, need to round it based on the min quantity and min notonial.

can someone please share some solution/suggestion for this?

Hello
Is it possible to use "socks-proxy-agent" or "https-proxy-agent"?
I added a proxy agent object to binance constructor options as "agent" -like how i do in ccxt- but it doesn't work.

https://github.com/aarongarvey/binance/blob/2e50536197bc82ee99c9d06119659f46cd9c7ccd/lib/ws.js#L20

it should be eventHandler(this._beautifier.beautify(data, data.e + 'Event'));

I'm seeing a number if reports with ZenBot, Gekko and the CCXT projects of Binance users getting a Response Code 400 due to their internal system clocks skewing by more than 1 second. Apparently Binance required the timestamps on all signed requests to be within 1000ms of their internal time. The issue arises for Windows users where time syncrhronization is either turned off, or whose clocks have a large skew (as the time sync service in windows only updates once a day).

For this reason it may be a good idea to implement an NIST time sync based service directly into the binance module and use an internal clock for generating timestamps over the system clock.

For reference see the following issues

askmike/gekko#1663
ccxt/ccxt#936

I will admit that I am unsure of the feasibility of this task, but probably we shouldn't ever update the computer's system time as part of the process.

tried to look everywhere for it and I couldn't find it.
only request, just seems something trivial for an exchange api.

thanks,
Jose.

I am using the "onAllTickers" Web-socket method to check conditions in the markets. The method works fine, normally I receive the Array with the values like it is expected to work. But suddenly I receive a String and not a Array.

You can try the following code, to see what I am trying to explain.

const api = require('binance')
const ws = new api.BinanceWS(true)

ws.onAllTickers(data => {
  console.log(typeof data)
})

Hi, I'm trying to withdraw some funds but they always answer me with the code 1022. Used version 1.3.3

What have I investigated yet?

1. Checked if my API keys are correct (I did #newOrder which is SIGNED as well and it worked)
2. Checked if mandatory permissions have been enabled for those keys (had to tick withdrawal option on the permissions list and restrict my IP address)
3. Changed recvWindow to many different values between 5000-60000 with no results
4. Changed handleDrift to true with no result
5. Changed the _getTime() function to return new Date().getTime() + 10000; with no results (based on @zoeyg suggestion located in https://github.com/zoeyg/binance/issues/34)

My current configuration:

My withdrawal function:

Please advise

Update

Finally, I figured out what happened there. By adding a 'name' param like '[${STAGE}]: Main KS's wallet in ETH' it seems that your library does something wrong with building URL params because of the escape codes.

I suggest to fix it as it may cause unexpected and difficult to detect bugs.

Thanks!

When running the package in Heroku, the REST call parameters (options object) is logged to the console. Do you know why this might be so? Is there anywhere you are logging to stdout? I checked the request package dependency and although it has a debug switch, it does not seem to be the culprit.

For example the user data stream keep alive sends this to the console output:

2018-01-28T14:50:39.176301+00:00 app[worker.1]: {"url":"https://api.binance.com/api/v1/userDataStream?listenKey=xxxxxx","timeout":15000,"headers":{"X-MBX-APIKEY":"xxxxxx"},"method":"PUT"}

Hi.

Do you think it could be possible to make baseUrl an option ? After Binance outage, I noticed that https://us.binance.com was working for me while https://www.binance.com was not so it would have been nice to be able to pass the new url in the constructor.

Thanks for your work, I'm using your lib for my multi-exchange project (https://mpe-demo.crazyme.net/ui/#/exchanges/binance/prices/USDT-NEO)

Need the ability to terminate the websockets

I use TypeScript for my Node backends. Are you interested in a PR to add typings to this project?

I am writing a order manager and I need a way to keep track of orders as they enter the api and complete calling back out the callback. I am currently adding a guid but I don't want to have to edit every function to accept passing in a new parameter that it passes back later. Any work around you could think of? I want the ability to track the same buy order duplicated but two totally different orders.

Hey,

The binance module (1.3.1) is not working for me:

const binance = require('binance');

const client = new binance.BinanceRest({
  key: 'x',
  secret: 'y',
  timeout: 15000,
  recvWindow: 60000, // suggested by binance
  disableBeautification: false,
  handleDrift: true
});

client.account({}, console.log);

Returns the following:

Error: Response code 400
    at Request.request [as _callback] (/Users/pear/projects/gekko/node_modules/binance/lib/rest.js:90:34)
    at Request.self.callback (/Users/pear/projects/gekko/node_modules/request/request.js:186:22)

Setting this line to 1022 instead of 1021 did not fix it for me. Do you have any ideas?

Hi, can't seem to get user data websocket to work.
I tried the example on github but i get:

    ^

TypeError: Cannot read property 'then' of undefined

if i comment out 'then' it does nothing...

for single symbol

https://api.binance.com/api/v1/ticker/price?symbol=LTCBTC
{
  "symbol": "LTCBTC",
  "price": "4.00000200"
}

how to get the result 2 or more symbols?

[
  {
    "symbol": "LTCBTC",
    "price": "4.00000200"
  },
  {
    "symbol": "ETHBTC",
    "price": "0.07946600"
  }
