That makes it clearer
Hers is one way to do it, another is to use a for loop, but try the
simpler first
change your buy to buysig in your code
buysig = yourbuyconditions;
EndOfDay = cross( timenum(), 155959 ); //for end of trading day 160000
DoneTrade = flip(buysig,endofday);
buy = buysig and ref(donetrade,-1)==0;
