goanda

A Golang wrapper for the OANDA v20 API. Currently OANDA has wrappers for Python, Javascript and Java. Goanda exists to extend upon those languages because of the increasing popularity of Go and for a side prject I'm working on.

Features

Goanda can perform the following actions on your OANDA brokerage accounts:

• Get candlesticks of all instruments
• Create and update orders
• Get data on current and past trades on OANDA
• Close/scale out of trades you have open
• Close positions (not just trades)
• Get data on your account
  • NAV
  • Current % of used margin
  • Balance
  • And more!
• Get data on all your transactions
• Get all pricing data (bid/ask spread) on specific instruments

Requirements

• Go v1.9+

Note: This package was created by a third party, and was not created by anyone affiliated with OANDA

Usage

To use this package run go get github.com/awoldes/goanda then import it into your program and set it up following the snippets below.

Basic Example

I suggest creating a .env file for your project to keep your secrets safe! Make sure you add a .gitignore file.

~/project/.env

OANDA_API_KEY=
OANDA_ACCOUNT=

~/project/main.go

package main

import (
	"log"
	"os"

	"github.com/awoldes/goanda"
	"github.com/davecgh/go-spew/spew"
	"github.com/joho/godotenv"
)

func main() {
	err := godotenv.Load()
	if err != nil {
		log.Fatal("Error loading .env file")
	}
	key := os.Getenv("OANDA_API_KEY")
	accountID := os.Getenv("OANDA_ACCOUNT_ID")
	oanda := goanda.NewConnection(accountID, key, false)
	history := oanda.GetCandles("EUR_USD", "10", "S5")
	spew.Dump(history)
}

Look at the /examples directory for more!

TODO

API (in order of priority)

• Instrument endpoints (to get prices and the order book)
• Order endpoints (to create, get or update orders for an account)
• Trade enpoints (to get information on current trades)
• Position endpoints (to get information on current positions)
• Account endpoints (to get information on the account)
• Transaction endpoints (to get information on account transactions)
• Pricing endpoints (to get pricing of instruments)
• Streaming endpoints for Pricing & Transactions

Docs

• Write docs on how to use goanda
• Write example programs for goanda
• Write tests for goanda

Supporting Projects

Thank you to the following projects, they really helped me while I was developing this API

• JSON to Go from @mholt - this tool helped massively with all the structs that needed to be created.
• Spew from @davecgh - this tool was awesome to debug with.
