One method by which this could be done, is to create the table inside a Google Spreadsheet and share the link here. You can also give the Editing Rights to travi bhai or any other friends, and then you all can edit that sheet "while others can only view it and not edit it." In this method, the work load can be shared as well, and one person will not have to do the editing / updating work alone, on a daily basis.
As you already mentioned, this cannot be done directly in traderji, because it does not allow multiple editing of single post over many days.
If any doubts in this Google Spreadsheet Method, then please ask, I will explain more.
Thanks and best regards
