MagicNumber Trailing Stop - MetaTrader 4 Expert | MT4 EA Download

Trailing Stop really supports our trades by moving the stop loss to the profit area so that we can always automatically protect our trades.

We will start the code by specifying the input trailing stop parameters

 Enter boolean Yes Trailing Stop= True ; //Trailing Stop
Input integer trailing start = 15 ; //Trace starting point (point)
Input integer trailing step = 5 ; //Tracking step size (points)

Input integer magic number = 0 ; //magic number

global variables

 //variable global
double mypoints = 0.0 ;

When we run this EA, the OnInit () function will be executed for the first time, in which we will validate and initialize the input variables.

 Integer initialization ()
  {
 
if (isTrailingStop && TrailingStart <= 0 ){
alert ( "Parameter is incorrect" );
return ( INIT_PARAMETERS_INCORRECT );
  }
  
   myPoint = GetPipPoint( symbol ());
  
Return ( initialization successful );
  }

Whenever a price change (quote change) occurs on the chart of this EA pair, the OnTick () function will be executed. The setTrailingStop() function will be called in the OnTick() function.

 Blank check ()
  { //--- setTrailingStop(MagicNumber);
  
   }

Function setTrailingStop()

Blank to set trailing stop( integer magic number = 0 ){
if (isTrailingStop== wrong ) return ;
  
integer order = 0 ;
string pair = "" ;
Double sl = 0.0 , tp = 0.0 ;
  
   pair= symbol ();
  
   Orders= Total number of orders ();
order ( integer i=t order - 1 ; i >= 0 ; i -) {
boolean hourSelect = orderSelect (i, SELECT BY POS, MODE_TRADES);
if (OrderMagicNumber() == magicNumber && string search (OrderSymbol(), right, 0 ) == 0 ){
if (orderType() == OP_BUY){
if ((Bid - (trailingStart * myPoint)) >= OrderOpenPrice()
                  && (Bid- ((trailingStart+trailingStep) * myPoint) >= OrderStopLoss() )
                )
            {
              sr = normalized double (bid - (trailingStart * myPoint), number ());
if (!OrderModify(OrderTicket(), OrderOpenPrice(), sl, OrderTakeProfit(), 0 , clear blue )) {
Print ( "#" , Order Ticket(), "Gajal Update SL" );
              }
            }
        }
  
if (orderType() == OP_SELL){
if ((Ask + (trailingStart * myPoint)) <= OrderOpenPrice()
                  && ( (Ask + ((trailingStart+trailingStep) * myPoint) <= OrderStopLoss() ) || OrderStopLoss() == 0.0 )
              )
            {
              sl = normalized double (Ask + (trailingStart * myPoint), number ());
if (!OrderModify(OrderTicket(), OrderOpenPrice(), sl, OrderTakeProfit(), 0 , clear blue )) {
Print ( "#" , Order Ticket(), "Gajal Update SL" );
              }
            }
        }
      } //End if magicNumber } //End }

The other standard function required is GetPipPoint()

// Fungsi gets PipPoint
Double points gained (pair of strings )
{
Double points = 0.0 ;
Integer number = ( integer ) MarketInfo(pair, MODE_DIGITS);
if (number == 2 || number == 3 ) points = 0.01 ;
else if (number == 4 || number == 5 ) points = 0.0001 ;
return (view);
}
