MQL5 sendmail. EA only sends me an email one time and then it stops placing new trades, help.

[Aesen Noah Remolacio Perez]

Why does my EA send me an email of the last deal's profit only once upon initializing the EA onto a chart and then after that it completely stops placing new trades?

The way i'm trying to make this code work is, whenever a position closes, i want my EA to send me an email notification of the most recent deal closed result. So that i don't have to keep checking my MT5 account to see my profits/loss

i have been struggling to figure this out for weeks can somebody anybody help me please

This is the code that i am trying to edit:

//global scope
//--- input parameters
input uchar    InpN        = 1;  // N
input datetime InpFromDate = 0;  // From Date (D'1970.01.01 00:00' -> OFF parameter)
input string   InpSymbol   = ""; // Symbol ("" -> all symbols)
input long     InpMagic    = -1; // Magic number (<0 -> all magics)
//---
datetime m_from_date       = 0;  // "0" -> D'1970.01.01 00:00';
//+------------------------------------------------------------------+
//| Expert initialization function                                   |

int OnInit(){

//--- request trade history
   HistorySelect(m_from_date,TimeTradeServer()+60*60*24*3);

   string text="";
//--- for all deals
