Implement ForeignScrapperer interface at pkg/dia/scraper/foreign-scrapers/Scrapper.go file 
type ForeignScrapperer interface {
	UpdateQuotation() error
	GetQuoteChannel() chan *models.ForeignQuotation
}
Add the scraper implementation a MyForeignScraper.go Golang file to pkg/dia/scraper/foreign-scrapers/ folder and add the next implementations: 
func (scraper *MyForeignScraper) Pool() chan dia.Pool {}
func (scraper *MyForeignScraper) Done() chan bool {}

Add a constructor for the scraper:
func NewMyForeignScraper(exchange dia.Exchange) *MyForeignScraper {}

Add MyForeignScraper case at scraper file cmd/foreignscraper/foreign.go:

	case "MyForeignScraper":
		log.Println("Start scraping data")
		sc = scrapers.NewMyForeignScraper(ds)
