go-binance

A Golang SDK for binance API.

All the REST APIs listed in binance API document are implemented, as well as the websocket APIs.

For best compatibility, please use Go >= 1.8.

Make sure you have read binance API document before continuing.

REST API

Setup

Init client for API services. Get APIKey/SecretKey from your binance account.

var (
    apiKey = "your api key"
    secretKey = "your secret key"
)
client := binance.NewClient(apiKey, secretKey)
futuresClient := binance.NewFuturesClient(apiKey, secretKey)

A service instance stands for a REST API endpoint and is initialized by client.NewXXXService function.

Simply call API in chain style. Call Do() in the end to send HTTP request.

Following are some simple examples, please refer to godoc for full references.

Create Order

order, err := client.NewCreateOrderService().Symbol("BNBETH").
        Side(binance.SideTypeBuy).Type(binance.OrderTypeLimit).
        TimeInForce(binance.TimeInForceTypeGTC).Quantity("5").
        Price("0.0030000").Do(context.Background())
if err != nil {
    fmt.Println(err)
    return
}
fmt.Println(order)

// Use Test() instead of Do() for testing.

Get Order

order, err := client.NewGetOrderService().Symbol("BNBETH").
    OrderID(4432844).Do(context.Background())
if err != nil {
    fmt.Println(err)
    return
}
fmt.Println(order)

Cancel Order

_, err := client.NewCancelOrderService().Symbol("BNBETH").
    OrderID(4432844).Do(context.Background())
if err != nil {
    fmt.Println(err)
    return
}

List Open Orders

openOrders, err := client.NewListOpenOrdersService().Symbol("BNBETH").
    Do(context.Background())
if err != nil {
    fmt.Println(err)
    return
}
for _, o := range openOrders {
    fmt.Println(o)
}

List Orders

orders, err := client.NewListOrdersService().Symbol("BNBETH").
    Do(context.Background())
if err != nil {
    fmt.Println(err)
    return
}
for _, o := range orders {
    fmt.Println(o)
}

List Ticker Prices

prices, err := client.NewListPricesService().Do(context.Background())
if err != nil {
    fmt.Println(err)
    return
}
for _, p := range prices {
    fmt.Println(p)
}

Show Depth

res, err := client.NewDepthService().Symbol("LTCBTC").
    Do(context.Background())
if err != nil {
    fmt.Println(err)
    return
}
fmt.Println(res)

List Klines

klines, err := client.NewKlinesService().Symbol("LTCBTC").
    Interval("15m").Do(context.Background())
if err != nil {
    fmt.Println(err)
    return
}
for _, k := range klines {
    fmt.Println(k)
}

List Aggregate Trades

trades, err := client.NewAggTradesService().
    Symbol("LTCBTC").StartTime(1508673256594).EndTime(1508673256595).
    Do(context.Background())
if err != nil {
    fmt.Println(err)
    return
}
for _, t := range trades {
    fmt.Println(t)
}

Get Account

res, err := client.NewGetAccountService().Do(context.Background())
if err != nil {
    fmt.Println(err)
    return
}
fmt.Println(res)

Start User Stream

res, err := client.NewStartUserStreamService().Do(context.Background())
if err != nil {
    fmt.Println(err)
    return
}
fmt.Println(res)

Websocket

You don't need Client in websocket API. Just call binance.WsXxxServe(args, handler, errHandler).

Depth

wsDepthHandler := func(event *binance.WsDepthEvent) {
    fmt.Println(event)
}
errHandler := func(err error) {
    fmt.Println(err)
}
doneC, stopC, err := binance.WsDepthServe("LTCBTC", wsDepthHandler, errHandler)
if err != nil {
    fmt.Println(err)
    return
}
// use stopC to exit
go func() {
    time.Sleep(5 * time.Second)
    stopC <- struct{}{}
}()
// remove this if you do not want to be blocked here
<-doneC

Kline

wsKlineHandler := func(event *binance.WsKlineEvent) {
    fmt.Println(event)
}
errHandler := func(err error) {
    fmt.Println(err)
}
doneC, _, err := binance.WsKlineServe("LTCBTC", "1m", wsKlineHandler, errHandler)
if err != nil {
    fmt.Println(err)
    return
}
<-doneC

Aggregate

wsAggTradeHandler := func(event *binance.WsAggTradeEvent) {
    fmt.Println(event)
}
errHandler := func(err error) {
    fmt.Println(err)
}
doneC, _, err := binance.WsAggTradeServe("LTCBTC", wsAggTradeHandler, errHandler)
if err != nil {
    fmt.Println(err)
    return
}
<-doneC

User Data

wsHandler := func(message []byte) {
    fmt.Println(string(message))
}
errHandler := func(err error) {
    fmt.Println(err)
}
doneC, _, err := binance.WsUserDataServe(listenKey, wsHandler, errHandler)
if err != nil {
    fmt.Println(err)
    return
}
<-doneC

Setting Server Time

Your system time may be incorrect and you may use following function to set the time offset based off Binance Server Time:

// use the client future for Futures
client.NewSetServerTimeService().Do(context.Background())

Or you can also overwrite the TimeOffset yourself:

client.TimeOffset = 123
