We invest and / or trade in the same stocks we publish. Below is doc from Google Sheets (google's version of Excel). Google Sheets has a very cool feature which allows the Current Market price of a stock or index to be automatically updated directly from Google Finance. If a trade is closed, then we remove the CMP price of that stock. (Note that google's data feed for the Current Market price column maybe delayed by upto 20 minutes).
New Feature as on 11 Dec 2017 : Once every week, we will upload a screenshot (JPG or PNG file) of the same sheet as verification that there is no tampering or changes made later in our entry or exit price, entry or exit dates.
