Hey Morris,
Great stuff! I went through the code. Everything is clear.
Thank you
BTW I discovered for myself finnhub.io. They have a lot interesting stuff. Would be cool to have Zorro connection to it
e.g. this snip gives you all the instruments from different forex providers they support (incl. Oanda)
import fhub
hub = fhub.Session(token)
All_FX = pd.concat((hub.symbols(exch,kind='forex').assign(source = exch)
for exch in hub.exchanges('forex').forex), ignore_index = True)
