Currency:

• Add helper method to currency pairs to return a match either base or quote.

Happy with changes, just need exchange_wrapper_standards addressing: https://github.com/thrasher-corp/gocryptotrader/actions/runs/8074480255/job/22059833368?pr=1404#step:9:292 For Kucoin, the &order.Submit needs leverage there since you now require it to be sent For gateio, GetActiveOrders, is more confusing to me since a pair should be sent. Anyway, those just need fixing up
