Coding Function OnTick:

void OnTick() { if(Digits==3 || Digits==5) pt=10*Point; else pt=Point; LabelPutih(); if(UseTrailingStop) trailing_stop(); if(UseTPinMoney && TPinMoney<= money()) closeall(); double candle2high = iHigh(Symbol(),NULL,2); double candle2low = iLow(Symbol(),NULL,2); double candle2open = iOpen(Symbol(),NULL,2); double candle2close = iClose(Symbol(),NULL,2); double candle2bullish = candle2close > candle2open; double candle2bearish = candle2close < candle2open; double MA3shift1 = iMA(Symbol(),NULL,PeriodMA3,0,MODE_SMA,PRICE_CLOSE,1); if(candle2bullish && MA3shift1 > candle2close) signal=1;//aturan buy if(candle2bearish && MA3shift1 < candle2close) signal=2;//aturan sell if(Jam_trade()==1) { if(SL==0) slb=0; else slb=Ask-SL*pt; if(SL==0) sls=0; else sls=Bid+SL*pt; if(TP==0) tpb=0; else tpb=Ask+TP*pt; if(TP==0) tps=0; else tps=Bid-TP*pt; if(wt!=Time[0]) { if(jumlahorder(0)<MaxOrder && TradeBuy && signal==1) { tiket = OrderSend(Symbol(),OP_BUY,NR(Lots),Ask,3,slb, tpb,"EA OP Buy",Magic,0,Blue); } if(jumlahorder(1)<MaxOrder && TradeSell && signal==2) { tiket = OrderSend(Symbol(),OP_SELL,NR(Lots),Bid,3,sls, tps,"EA OP Sell",Magic,0,Red); } if(tiket>0) wt=Time[0]; } } }

Coding Function Jam Trading EA:

int JamTrade() { bool trade = false; if(MulaiJam > AkhirJam) { if(Hour() >= MulaiJam || Hour() < AkhirJam) trade = true; } else if(Hour() >= MulaiJam && Hour() < AkhirJam) trade = true; return (trade); }

Coding Function JumlahTransaksi:

int JumlahOrder(int tipe) { int total=0; for(int i=0; i<OrdersTotal(); i++) { if(!OrderSelect(i,SELECT_BY_POS,MODE_TRADES)) continue; if(OrderSymbol()!=Symbol() || OrderMagicNumber()!=Magic || OrderType()!=tipe) continue; total++; } return(total); }

Coding Function Normalisasi Lot:

double NR(double thelot) { double maxlots = MarketInfo(Symbol(), MODE_MAXLOT), minilot = MarketInfo(Symbol(), MODE_MINLOT), lstep = MarketInfo(Symbol(), MODE_LOTSTEP); double lots = lstep * NormalizeDouble(thelot / lstep, 0); lots = MathMax(MathMin(maxlots, lots), minilot); return (lots); }

Coding Function TrailingStop:

void trailing() { for(int i=0; i<OrdersTotal(); i++) { if(!OrderSelect(i,SELECT_BY_POS,MODE_TRADES)) continue; if(OrderSymbol()!=Symbol() || OrderMagicNumber()!=Magic) continue; if(OrderType()==OP_BUY) { if(Bid-OrderOpenPrice()>pt*TrailingStop) { if((OrderStopLoss()<Bid-pt*TrailingStop) || (OrderStopLoss()==0)) { tiket=OrderModify(OrderTicket(),OrderOpenPrice(),Bid-pt*TrailingStop,OrderTakeProfit(),0,Green); } } } if(OrderType()==OP_SELL) { if((OrderOpenPrice()-Ask)>(pt*TrailingStop)) { if(OrderStopLoss()>(Ask+pt*TrailingStop) || (OrderStopLoss()==0)) { tiket=OrderModify(OrderTicket(),OrderOpenPrice(),Ask+pt*TrailingStop,OrderTakeProfit(),0,Red); } } } } }

Coding Function CloseAll:

void CloseAll() { for(int i = OrdersTotal() - 1; i >= 0; i--) { if(!OrderSelect(i,SELECT_BY_POS,MODE_TRADES)) continue; if(OrderSymbol() != Symbol() || OrderMagicNumber()!=Magic) continue; if(OrderType() > 1) tiket=OrderDelete(OrderTicket()); else { if(OrderType() == 0) tiket=OrderClose(OrderTicket(), OrderLots(), Bid, 3, CLR_NONE); else tiket=OrderClose(OrderTicket(), OrderLots(), Ask, 3, CLR_NONE); } } }

Coding Function TPinMoney:

double money() { double dp = 0; int i; for(i = 0; i < OrdersTotal(); i++) { if(!OrderSelect(i, SELECT_BY_POS, MODE_TRADES)) continue; if(OrderSymbol() != Symbol() || OrderMagicNumber()!=Magic) continue; dp += OrderProfit(); } return(dp); }

Coding Function Info Akun:

void LabelPutih() { Comment("\n\nBalance: ", DoubleToStr(AccountBalance(),2), "\n\nEquity: ", DoubleToStr(AccountEquity(),2), "\n\nFloating: ", DoubleToStr((AccountEquity()-AccountBalance()),2), "\n\nJumlah Buy ", jumlahorder(0), " Jumlah Sell ", jumlahorder(1), "\n\nOrders Total ", OrdersTotal(), "\n\n ", AccountCompany(), "\n\n ", AccountName(), ""); }
