getInstrument() to take TimePeriod

[ZachariasHultman]

Hi!

Is there any way of getting the information from getInstrument() for a specific year or day? With new updates to avanza app you are able to see for example the last 5 years P/E values. This information should be able to get with this api swell? How?
