Setup

Creating a client:

import (
	"os"
	"go-binance/binance"
)

// Secure method
secret := os.Getenv("BINANCE_SECRET")
key    := os.Getenv("BINANCE_KEY")

// Unsecure method
secret := "mySecret"
key    := "myKey"

client :=  binance.New(secret, key)

Examples

Get Current Positions

package main

import (
    "os"
    "fmt"
    "github.com/pdepip/go-binance/binance"
)

func main() {

    client := binance.New(os.Getenv("BINANCE_KEY"), os.Getenv("BINANCE_SECRET"))
    positions, err := client.GetPositions()

    if err != nil {
        panic(err)
    }

    for _, p := range positions {
        fmt.Println(p.Asset, p.Free, p.Locked)
    }
}

Place a Limit Order

package main

import (
	"os"
	"fmt"

        Symbol:      "BNBBTC",
        Side:        "BUY",
        Type:        "LIMIT",

        Quantity:    50.0,
        Price:       0.00025,
    }

    client := binance.New(os.Getenv("BINANCE_KEY"), os.Getenv("BINANCE_SECRET"))
    res, err := client.PlaceLimitOrder(order)
    
    if err != nil {
    	panic(err)
    }
    
    fmt.Println(res)
}
