# Implementation
|
|
|
|
|
|
|
|
|
|
Go to `pkg/types/exchange.go` and add your exchange type:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
const (
|
|
|
|
|
ExchangeMax = ExchangeName("max")
|
|
|
|
|
ExchangeBinance = ExchangeName("binance")
|
|
|
|
|
ExchangeFTX = ExchangeName("ftx")
|
|
|
|
|
ExchangeOKEx = ExchangeName("okex")
|
|
|
|
|
ExchangeKucoin = ExchangeName("kucoin")
|
|
|
|
|
ExchangeBacktest = ExchangeName("backtest")
|
|
|
|
|
)
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Go to `pkg/cmd/cmdutil/exchange.go` and add your exchange to the factory
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
func NewExchangeStandard(n types.ExchangeName, key, secret, passphrase, subAccount string) (types.Exchange, error) {
|
|
|
|
|
switch n {
|
|
|
|
|
|
|
|
|
|
case types.ExchangeFTX:
|
|
|
|
|
return ftx.NewExchange(key, secret, subAccount), nil
|
|
|
|
|
|
|
|
|
|
case types.ExchangeBinance:
|
|
|
|
|
return binance.New(key, secret), nil
|
|
|
|
|
|
|
|
|
|
case types.ExchangeOKEx:
|
|
|
|
|
return okex.New(key, secret, passphrase), nil
|
|
|
|
|
|
|
|
|
|
// ...
|
|
|
|
|
}
|
|
|
|
|
}
|
|
|
|
|
```
|
|
|
