I need to graph daily and weekly limits, open session values

I need an indicator to graph the following values as lines on the graph on a historic basis (not only for the curren day and week):

// WEEKLY LIMITS

Limit_2_Long  = iClose(NULL,PERIOD_W1,1) + iClose(NULL,PERIOD_W1,1)*weekly_Limit/100 ; 

Limit_2_Short = iClose(NULL,PERIOD_W1,1) - iClose(NULL,PERIOD_W1,1)*weekly_Limit/100 ;   

// Where weekly limit is an input variable



// DAILY LIMITS

Limit_1_Long  = iClose(NULL,PERIOD_D1,1) + iClose(NULL,PERIOD_D1,1)*daily_Limit/100 ; 

Limit_1_Short = iClose(NULL,PERIOD_D1,1) - iClose(NULL,PERIOD_D1,1)*daily_Limit/100 ;   

// Where daily limit is an input variable

EXCEPTIONS FOR DAX AND BUND AS FOLLOW:

// DAILY CLOSE AS REFER TO CALCULATE LIMITS 
 if (Hour()==Euro_end_session+1 && Minute()==0)
     { 
     Daily_close = iClose(NULL,PERIOD_H1,0)  ;
     }


// WEEKLY CLOSE AS REFER TO CALCULATE LIMITS 
if (Hour()==Euro_end_session+1 && Minute()==0 && DayOfWeek()==5)
     { 
     Weekly_close = iClose(NULL,PERIOD_H1,0)  ;
     }
// Where Euro_end_session is an input variable

Open session values: this should be a white line that shifts on every new session, with external inputs to decide which session to use (for instance I wante to use Asian - Europe- US for EURJPY but only Europe and US for DAX). Also previous days values is required.

//+------------------------------------------------------------------+ 
//| ASIAN SESSION                                                          |                                           
//+------------------------------------------------------------------+ 

     
    if (Hour()==Asian_open+1)  // where Asian_open is an input variable
        {                   
        Open_LIne = iOpen(NULL,PERIOD_H1,0) ;                                            
        } 
        
        
//+------------------------------------------------------------------+ 
//| UE SESSION                                                              |                                           
//+------------------------------------------------------------------+ 

     
    if (Hour()==Euro_open+1)  // where Euro_open is an input variable
        {              
        Open_LIne = iOpen(NULL,PERIOD_H1,0) ;      
        } 
              

//+------------------------------------------------------------------+ 
//| US SESSION                                                              |                                           
//+------------------------------------------------------------------+ 

     
    if (Hour()==US_open+1)  // where US_open is an input variable
        {               
        Open_LIne = iOpen(NULL,PERIOD_H1,0) ;  
        }
