-## FTX Exchange
-
-### Current Features
-
-+ REST Support
-+ Websocket Support
-
-### 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 f exchange.IBotExchange
-
-for i := range bot.Exchanges {
-	if bot.Exchanges[i].GetName() == "FTX" {
-		f = bot.Exchanges[i]
-	}
-}
-
-// Public calls - wrapper functions
-
-// Fetches current ticker information
-tick, err := f.FetchTicker()
-if err != nil {
-	// Handle error
-}
-
-// Fetches current orderbook information
-ob, err := f.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 := f.GetAccountInfo()
-if err != nil {
-	// Handle error
-}
-```
-
-+ If enabled via individually importing package, rudimentary example below:
-
-```go
-// Public calls
-
-// Fetches current ticker information
-ticker, err := f.GetTicker()
-if err != nil {
-	// Handle error
-}
-
-// Fetches current orderbook information
-ob, err := f.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 := f.GetUserInfo(...)
-if err != nil {
-	// Handle error
-}
-
-// Submits an order and the exchange and returns its tradeID
-tradeID, err := f.Trade(...)
-if err != nil {
-	// Handle error
-}
