Unofficial Golang Interactive Brokers API (Beta)

This package provides an unofficial Golang implementation of the Interactive Brokers API. It is designed to mirror the official Python or C++ tws-api provided by Interactive Brokers. We will do our best to keep it in sync with the official API releases to ensure compatibility and feature parity, but users should be aware that this is a community-driven project and may lag behind the official versions at times.

Note: This package is in the beta phase. While functional, it may still have bugs or incomplete features. Please test extensively in non-production environments.

Getting Started

Prerequisites

• Go version 1.23 or higher (recommended)
• An Interactive Brokers account with TWS or IB Gateway installed and running

Installation

Install the package via go get:

go get -u github.com/scmhub/ibapi

Usage

Here’s a basic example to connect and place an order using this package:

package main

import (
	"math/rand"
	"time"

	"github.com/scmhub/ibapi"
)

const (
	IB_HOST = "127.0.0.1"
	IB_PORT = 7497
)

func main() {
	// We set logger for pretty logs to console
	log := ibapi.Logger()
	ibapi.SetConsoleWriter()

	// New IB CLient
	ib := ibapi.NewEClient(nil)
    // Connect client
	if err := ib.Connect(IB_HOST, IB_PORT, rand.Int63n(999999)); err != nil {
		log.Error().Err(err)
		return
	}

    // Create and place order
	id := ib.NextID()
	eurusd := &ibapi.Contract{Symbol: "EUR", SecType: "CASH", Currency: "USD", Exchange: "IDEALPRO"}
	limitOrder := ibapi.LimitOrder("BUY", ibapi.StringToDecimal("20000"), 1.08)
	ib.PlaceOrder(id, eurusd, limitOrder)

	time.Sleep(1 * time.Second)

	err := ib.Disconnect()
	if err != nil {
		log.Error().Err(err).Msg("Disconnect")
	}
}
