Last week, (2/26/2018 specifically,) PCLN (priceline.com) converted to a new ticker BKNG (bookings.com).
I have not found anyplace that has a completed 10 year+ history on the company.
Like your site, the YTD and all other history is limited to starting at 2/26/2018 to the current day.
Unlike some other sites, indx.guru no longer has PCLN data available.
PCLN historical data must be concatenated with BKNG data to create a single succinct history.
This would be an edge only you would have.
