The usual technique is to wait until the first bar of the day then refer to the values of variables back one bar. For example:

   NP = NetProfit;

   if Date <> Date[1] then begin
      XXX = Close[1];
      YYY = NP[1];
   end;

This usually works for finding values but not for issuing signal for the first bar of the day.

You can also say:

   if Time = 1615 then .....
   if Time = Sess1EndTime then .....

and this works if there is a bar with that time stamp. It usually works except on days when the market closes early.
