Bitmex API

Packages for work with bitmex rest and websocket API on golang.
Target of this packages make easy access to bitmex API including testnet platform.

Usage

Please see full example in main.go

REST

// Load config
cfg := config.LoadConfig("config.json")
ctx := rest.MakeContext(cfg.Key, cfg.Secret, cfg.Host)

// Get wallet
wallet, response, err := rest.GetWallet(ctx)
tools.CheckErr(err)
fmt.Printf("Status: %v, wallet amount: %v\n", response.StatusCode, wallet.Amount)

// Place order
params := map[string]interface{}{
    "side":     "Buy",
    "symbol":   "XBTUSD",
    "ordType":  "Limit",
    "orderQty": 1,
    "price":    9000,
    "clOrdID":  "MyUniqID_123",
    "execInst": "ParticipateDoNotInitiate",
}
order, response, err := rest.NewOrder(ctx, params)
tools.CheckErr(err)
fmt.Printf("Order: %+v, Response: %+v\n", order, response)

Websocket

// Load config
cfg := config.LoadConfig("config.json")

// Connect to WS
conn := websocket.Connect(cfg.Host)
defer conn.Close()

// Listen read WS
chReadFromWS := make(chan []byte, 100)
go websocket.ReadFromWSToChannel(conn, chReadFromWS)

// Listen write WS
chWriteToWS := make(chan interface{}, 100)
go websocket.WriteFromChannelToWS(conn, chWriteToWS)

// Authorize
chWriteToWS <- websocket.GetAuthMessage(cfg.Key, cfg.Secret)

// Listen
go func() {
    for {
        message := <-chReadFromWS
        res, err := bitmex.DecodeMessage(message)
        tools.CheckErr(err)

        // Business logic
        switch res.Table {
        case "orderBookL2":
            if res.Action == "partial" {
                // Update table
            } else {
                // Update row
            }
        case "order":
            if res.Action == "partial" {
                // Update table
            } else {
                // Update row
            }
        case "position":
            if res.Action == "partial" {
                // Update table
            } else {
                // Update row
            }
        }
    }
}()

bitmex's Issues

rest.NewOrder wrong market

rest.NewOrder() calls client.OrderApi.OrderNew() with the symbol always set to "XBTUSD" regardless of parameters. needs to be fixed as most users will not notice it and always trade with "XBTUSD" even if specified differently.

Bitmex is not working with his ws label.
