Need help, MQL4 first timer...

Hello everybody, thank you very much for any support you would kindly give me.

I am a newbi in programming and I am trying to make this few lines work... It is very simple stuff: when I press the "u" button, it opens a buy order, when I press the "n" button, a sell order is triggered.

Then, it checks which kind of order is opened (but or sell) and it applies a trailing stop according to the parameters ("spostamento/shifting" and "profitto/prifit" I put in an editable field together with the lots number "lotti").

This is the "Frankenstein code" I put together :), I run it and... nothign happens!! :D

string CampoTesto[1000];
double Profitto;
double Spostamento;
double Lotti;

double NewSL=0;


int OnInit()
  {    
    creazioneSfondo("Sfondo");
    creaCampoEditabile("Profitto","Pips di profitto",75,150,150,30,clrWhite,clrGray);
    creaCampoEditabile("Spostamento","Spostamento SL [pips]",75,200,150,30,clrWhite,clrGray);
    creaCampoEditabile("Lotti","Numero di Lotti",75,250,150,30,clrWhite,clrGray);
    
   return(INIT_SUCCEEDED);
  }

         }

             }

Done, sorry for not doing it but I am a real newbi to the forum too.

Always use

#property strict

Read the documentation for OrderSend and check the return value. Print the error if necessary.

if(OrdersTotal()>0)
      
      if(!OrderSelect(0,SELECT_BY_TICKET,MODE_TRADES)){
       Print("Errore Ordine Select #",GetLastError());
      }

There will never be a trade with the ticket #0

Thank you Keith,

yes I used #propery strict but didn't mention it.

You are right, I should selcet by position and not by trade...

Why do you think the keyboard event is not working?

Also print something when the key is pressed in order to check.

Thank you Keith for your help, but I am still not getting the point... Is it a ridicuolous idea to ask you exactly what should I do?
