## Bittrex Exchange
### Current Features
+ REST Support
### Notes
- Bittrex used to have reversed market names: btc-ltc. The v3 API changed this to the more widely accepted format with first the base pair and then the quote pair: ltc-btc.
- Asset names and market names are not case sensitive.
### How to enable
+ [Enable via configuration](https://github.com/thrasher-corp/gocryptotrader/tree/master/config#enable-exchange-via-config-example)
+ Individual package example below:
```go
// 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
```go
var b exchange.IBotExchange
for i := range bot.Exchanges {
if bot.Exchanges[i].GetName() == "Bittrex" {
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:
```go
// 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
}
```
