Trader

Introduction

Trader is a framework that automated cryptocurrency exchange with strategy.

Disclaimer: The profit and loss is yourself when use this framework!

Features

• Current support spot/future of binance, more exchange work in progress.
• Easy write your own strategy.
• Back test engine support to test your strategy.
• Restful api server integration.

Quick Start

Write Strategy

Just see examples

Inherit strategy.Base

package strategy

type UpDownRate struct {
	strategy.Base
}

Implement OnConnect and On1mKline, or OnTicker.

package strategy

func (s *UpDownRate) OnConnect() {
	// you can do something initialization here.
}

func (s *UpDownRate) On1mKline() {
	// here you can buy or sell order depending on 1m kline.
}

Back test strategy

The result will store in orders table in database.

package tests

func TestUpDownRate(t *testing.T) {
	conf.InitConfig("config.yml")
	eng := (*engine.GetEngine(exchange.Mock, conf.BinanceApiKey, conf.BinanceApiSecret)).(*engine.Mock)
	BaseAsset := "ETH"
	QuoteAsset := "USDT"
	symbol := BaseAsset + QuoteAsset
	h, _ := time.ParseDuration("-48h")
	eng.Exchange.(*mock.Mock).StartTime = time.Now().Add(h)
	eng.Exchange.(*mock.Mock).EndTime = time.Now()
	eng.Exchange.(*mock.Mock).Symbol = symbol

	eng.RegisterStrategy(&UpDownRate{
		KLineLimit: 10,
		Rate:       decimal.NewFromInt(6).Div(decimal.NewFromInt(4)),
		Base: strategy.Base{
			Streams:    []string{strings.ToLower(symbol) + "@kline_1m"},
			FundRatio:  decimal.NewFromFloat(1),
			StopProfit: decimal.NewFromFloat(0.02),
			StopLoss:   decimal.NewFromFloat(0.06),
			BaseAsset:  BaseAsset,
			QuoteAsset: QuoteAsset,
			Exchange:   eng.Exchange,
		}},
	)
	eng.Start(false)
}

Run strategy

After test strategy, and it's effective, that's the time to run it.

package main

func main() {
	conf.InitConfig("config.yml")
	eng := (*engine.GetEngine(exchange.BinanceSpot, conf.BinanceApiKey, conf.BinanceApiSecret)).(*engine.Engine)
	eng.RegisterStrategy(&UpDownRate{
		KLineLimit: 10,
		Rate:       decimal.NewFromInt(6).Div(decimal.NewFromInt(4)),
		Base: strategy.Base{
			FundRatio:  decimal.NewFromFloat(1),
			StopProfit: decimal.NewFromFloat(0.02),
			StopLoss:   decimal.NewFromFloat(0.06),
			BaseAsset:  "ETH",
			QuoteAsset: "USDT",
			Exchange:   eng.Exchange,
			Streams:    []string{"ethusdt@kline_1m", "ethusdt@miniTicker"},
		}},
	)
	eng.Start(true)
}

Back test

Trader has a back test engine, for that you can test your strategy.

Config

Copy config.example.yaml to config.yaml then update it, and current use MySQL.

You can get other custom config by viper.GetString() etc, see viper framework for more details.

Run trader

Also see examples.

INFO[0005] Start trader success   

You can earn BTC and ETH when sleep now!
