Belajar Membuat EA Sederhana 25 (Cut Switching)


Belajar Membuat EA Sederhana 25 (Cut Switching)

http://jumforex.blogspot.com/2013/02/belajar-membuat-ea-sederhana-25-cut.html

Mungkin sudah pada ngintip di part 24 

Kali ini kita akan bahas tentang EA model cut switching , saya sih juga gak begitu memahami betul tentang strategy ini tapi yang jelas ini termasuk juga EA martingel tapi untuk kondisi trending.

Ea ini setelah order maka bila floting negatif maka akan di cut loss dan dilanjutkan dengan order baru dengan arah yang berlawanan dengan memeperhitungkan kelipatan lotsnya

Nah sebenarnya bisa dibuat dengan beberapa model , tapi kali ini kita akan buat model menggunakan tidak menggunakan pending stop.
bagian triger digunakan indikator fractals
Perhatikan cara codingnya:

for(int d=0; d< Bars ; d++){ double up=iFractals(Symbol(),0,MODE_UPPER,d);     if(up!=0 ) break;} 
for(int e=0; e< Bars ; e++){ double lo=iFractals(Symbol(),0,MODE_LOWER,e); if( lo!=0) break;} 
int signal; 
if(Bid > up) signal=1;// signal buy 
if(Ask < lo)signal=2;//signal sell 


Bagian lain yang perlu diperhatikan adalah membaca history orderprofit, ordertype dan magic number

double trad(int m)

{
  double pr,op; 
  for (int i = 0; i < OrdersHistoryTotal(); i++) {
   if (!OrderSelect(i, SELECT_BY_POS, MODE_HISTORY)) continue;
   if (OrderSymbol() != Symbol()/* || OrderComment() != Nama_EA*/) continue;
   if(m==1)pr=OrderProfit();
   if(m==2)pr=OrderType();
   if(m==3)pr=OrderMagicNumber();
   }
return(pr);
}

  1. history orderprofit diperlukan untuk mengetahui orderprofit pada order close yang terakhir itu untung ata rugi
  2. history ordertype diperlukan untuk mengetahui type order pada order close yang terakhir itu type buy atau sell
  3. history magicnumber diperlukan untuk mengetahui membatasidan memperhitungkan level order 
Untuk memperhitungkan perkalian lotsnya digunakan fungsi sbb:

double xlot()
{
 double ylot,dlot; 
  for (int i = 0; i < OrdersHistoryTotal(); i++) {
   if (!OrderSelect(i, SELECT_BY_POS, MODE_HISTORY)) continue;
   if (OrderSymbol() != Symbol()/* || OrderComment() != Nama_EA */) continue;
     dlot=OrderLots();
     }
    ylot=NR(dlot*DiMarti);
return(ylot);
}



Untuk penentuan trigernya saya coba gunakan indikator Fractals

    Imagine if you had a robot with 6 years authenticated proof?

    I just completed a webinar with Mark and his partner, Antony, two days ago and it was AMAZING.

    During the webinar MARK and ANTONY shared their stories to success and answered questions about their new version of the GPS Forex Robot that CAME OUT TODAY!
