decide how exchanges should be handled #25

Closed wsteitz closed 11 years ago

wsteitz commented 11 years ago

every stock is listed at various stock exchanges. currently we do not care about this, and just show the price from one (random) exchange. we should at least choose the one with the largest volume or the one with the latest price.

i think it would be cool if a user could switch between a) a specific exchange b) the highest volume exchange or c) the lastest price exchange. the default setting would be b) or c).

comments?

(by wolfer7) yahoo.update_stock now uses the exchange with the most recent stock price

(by wolfer7) onvista.update_stock also uses the most recent stock price.

todo: yahoo.historical_data should always use the same exchange. which one?
