Here’s how to do PREV in a loop (I can’t check the code because I don’t have the deltav values, but this should give you an idea of what to do):

 

// MetaStock Code

 

// TLevel:= if(C=PREV,PREV,if(prev>Ref(C,-1),Min(C,deltav),Max(prev,C))));

 

 

TLevel = 0// Indicator to calculate, TLevel[i-1] = MetaStock PREV

 

PREV = 0;

 

for (i=1; i<BarCount; i++) {

 

       PREV[i] = TLevel[i-1];

 

       if(C[i] == PREV[i])

                     TLevel[i] = PREV[i];

              else {

                     if(PREV[i] > C[i-1]) {

                           if(C[i] < deltav[i])

                                  TLevel[i] = C[i];

                           else

                                  TLevel[i] = deltav[i];

                     }

                     else {

                           if(PREV[i] > C[i])

                                  TLevel[i] = PREV[i];

                           else

                                  TLevel[i] = C[i];

                     }

       }

 

}

My apologies ... you do need a loop. It is a circular reference
