The SecuritiesService

[oxisto]

The primary goal of the SecuritiesService is to provide pricing data and meta-data for various stock (options). According to our design goals, we can share the stocks information across all accounts / portfolio groups.

• Initial skeleton creation of SecuritiesService #23
• Connect securities service to storage backend #26

Metadata

Some of the meta-data we might want:

• Name
• ISIN
• Ticker Symbol
• WKN
• Currency
• Latest Price
• Historical Quotes (per day)

It might also be interesting to connect different stocks together. We could for example have the same stock on two different exchanges with two symbols. Also it would be nice if we have the information whether the stock is a derivate of another stock.

Open Question: How to name it? We also want to support other things next to stocks, maybe we need to name it Security?

Where do we get this information from?
