Bitstamp Exchange

Current Features
  • REST Support
  • Websocket Support
How to enable
  // Exchanges will be abstracted out in further updates and examples will be
  // supplied then
How to do REST public/private calls
  • If enabled via "configuration".json file the exchange will be added to the IBotExchange array in the go var bot Bot and you will only be able to use the wrapper interface functions for accessing exchange data. View routines.go for an example of integration usage with GoCryptoTrader. Rudimentary example below:

main.go

var b exchange.IBotExchange

for i := range bot.Exchanges {
  if bot.Exchanges[i].GetName() == "Bitstamp" {
    b = bot.Exchanges[i]
  }
}

// Public calls - wrapper functions

// Fetches current ticker information
tick, err := b.FetchTicker()
if err != nil {
  // Handle error
}

// Fetches current orderbook information
ob, err := b.FetchOrderbook()
if err != nil {
  // Handle error
}

// Private calls - wrapper functions - make sure your APIKEY and APISECRET are
// set and AuthenticatedAPISupport is set to true

// Fetches current account information
accountInfo, err := b.GetAccountInfo()
if err != nil {
  // Handle error
}
  • If enabled via individually importing package, rudimentary example below:
// Public calls

// Fetches current ticker information
ticker, err := b.GetTicker()
if err != nil {
  // Handle error
}

// Fetches current orderbook information
ob, err := b.GetOrderBook()
if err != nil {
  // Handle error
}

// Private calls - make sure your APIKEY and APISECRET are set and
// AuthenticatedAPISupport is set to true

// GetUserInfo returns account info
accountInfo, err := b.GetUserInfo(...)
if err != nil {
  // Handle error
}

// Submits an order and the exchange and returns its tradeID
tradeID, err := b.Trade(...)
if err != nil {
  // Handle error
}
How to do Websocket public/private calls
  // Exchanges will be abstracted out in further updates and examples will be
  // supplied then
