daily chart of NKD does not match with the daily chart on CME website

The daily chart of NKD H8 does not match witht the daily chart on CME website. As I said in other threads, it seems eSignal sometimes can not build daily OHLC data correctly for some futures.

This is the screenshot of eSignal NKD H8,D

The chart on CME website.

Which one is correct? To me, both of them do not exactly match the daily chart rebuilt from the intraday data, however it seems CME chart matchs better than eSignal's.

Just a thought- could this be pit vs electronic hours, I don't know what the hours are for this contract (re they different?) so just a guess.

They are all daily charts. Unless they use different rules to decide the open and close prices, they should be the same.
