EA sendmail problem persists

[Aesen Noah Remolacio Perez]

This was my previous problem https://www.mql5.com/en/forum/435434#comment_42935818 which has been solved

However, a new problem emerged that i'm needing help with.

When i load my EA onto a chart, immediately within seconds i get a email of the info i wanted to receive, but after that first email, my EA stops placing pending orders after the first pending orders expire or if price triggers a pending order and either hits my stop loss / take profit level. My EA stopped placing pending orders after i placed this code in the body of the on tick function: 

// In Global Scope
static datetime lastdealtime = 0;

//----------------------------------------------------------------------------------------------------------
//Send email alerts of last closed deals symbol & loss or profit amount in USD
//-----------------------------------------------------------------------------------------------------------      
//--- request trade history
   HistorySelect(0,TimeCurrent());
   uint total_deals=HistoryDealsTotal();
   ulong ticket_history_deal=0;
   int counter=0;
   string text="";
//--- for all deals
   for(uint i=total_deals-1; i>=0; i--){
   
      //--- try to get deals ticket_history_deal
      if((ticket_history_deal=HistoryDealGetTicket(i))>0){
      
         long     deal_ticket       =HistoryDealGetInteger(ticket_history_deal,DEAL_TICKET);
         long     deal_time         =HistoryDealGetInteger(ticket_history_deal,DEAL_TIME);
         long     deal_type         =HistoryDealGetInteger(ticket_history_deal,DEAL_TYPE);
         long     deal_entry        =HistoryDealGetInteger(ticket_history_deal,DEAL_ENTRY);
         long     deal_magic        =HistoryDealGetInteger(ticket_history_deal,DEAL_MAGIC);
         double   deal_commission   =HistoryDealGetDouble(ticket_history_deal,DEAL_COMMISSION);
         double   deal_swap         =HistoryDealGetDouble(ticket_history_deal,DEAL_SWAP);
         double   deal_profit       =HistoryDealGetDouble(ticket_history_deal,DEAL_PROFIT);
         string   deal_symbol       =HistoryDealGetString(ticket_history_deal,DEAL_SYMBOL);
         datetime m_from_date       = 0;
         uchar lastdeal = 1;
         //---                
         
         if((_Symbol==deal_symbol || _Symbol=="") && (Magic==deal_magic || Magic<0)){
         
            if(deal_entry==DEAL_ENTRY_OUT && deal_time>lastdealtime){
               
               counter++;
               string time=TimeToString((datetime)deal_time,TIME_DATE|TIME_MINUTES|TIME_SECONDS);
               SendMail(__FILE__, Symbol()+", $ "+DoubleToString(deal_commission+deal_swap+deal_profit,2));
               lastdealtime = (datetime)deal_time;
               if(counter==lastdeal){                  
               
                  m_from_date=(datetime)deal_time;
                  break;
                  }
               }
            }
         }
      }

and once i remove this code above and recompile it to test the EA on a live chart, it works normally and places pending orders every 2 minutes(expiry time 120 seconds) on the 1 minute chart.

Can someone please help me solve this. Why is my EA not placing orders whenever a signal is generated and how can i fix this? Thank you in advance!
