historical data: pre-market & after-hours trading data

hello I am interested to see how long it took for LinkedIn's stock price to surge to 49% pre-market on 06-13-2016.
Is there a way to access this historical data on viikate? I tried to tinker with the sample code but could not get info:

linkedin_minute_closes = get_pricing( 
 end_date = '2016-06-14', 

here was the output : screenshot

I tried google finance, yahoo finance, e-trade & charles schwab, none of them has a chart of this data.
News Article for reference, the news roughly hit the internet around 8:24AM:


Please let me know.

viikate only has price information during regular trading hours.

In general, when outside of trading hours, it's very hard to profit on information. It's not a liquid market where orders are being filled. (Obviously, there are lots of exceptions to this like futures markets and non-US exchanges, but we're not yet supporting any of those).
