How does bitcoin trading behave against gaps? - MQL4 and MetaTrader 4

Vitalie Postolache 2013.12.19 21:07 #3491

Forexman77:

In the picture, I have marked with an arrow where the output should be. I don't understand what the problem is. We go in, remember the time,

Then exit when the time is longer than the entry with an offset by one period and the price is below the 3-day MA min.

The code is as follows:

What do you think?

I mean it would be good to post screenshots where you can see the price and the timeframe. Maybe there is pipsing on M1 and the server just does not have time to process the order in time.

And instead of t=Time[0]; better use OrderOpenTime().

If it's not too secret, I mean it would be good to publish screenshots where you can see prices and timeframe. Maybe there is pipsing on M1 and the server just does not have time to process the order.

Use OrderOpenTime() instead of t=Time[0];.

Eureka! I understood why.

signal > 0.006 almost always, so t=Time[0]; is updated all the time and the trade does not close.

I put t=Time[0]; in the block where the fact of opening of a position is announced.

Hi all, how does the EA being tested behave against gaps? I.e. on the test it shows good profit, but on the demo it has been gapping everything for two days already :(.

[Deleted] 2013.12.20 06:18 #3494

Hi all!

I have made EA by crossing two EMAs, this is my first EA and i am afraid i made some silly mistakes, so i am asking the professionals to review the code and give me some advice if something is wrong.

This EA should trade on bitcoin exchange, the price may jump by 30% per day, so stoploss and takeprofit should be in percent of price.

I have tested it on demo account, it seems to work, but I am afraid to use it on real account, the minimum lot is about $ 7, and cent account has no broker.

I have not attached trailing stop yet, and I'm going to compare EMA difference not with zero, but with some small value, to avoid frequent trades when curves run parallel.

The program is mostly made up of bits and pieces plucked from examples and tutorials, so there's a concern that I might have messed up somewhere when putting it together.

Variables:

#property copyright "me"
#property link      "killnosock.net"
extern int SlowEma = 21;
extern int FastEma = 10;
extern int MaxRisk = 100;// % депо которое будет использоваться для открытия ордера
extern int  TakeProfit=100;
extern int  StopLoss=100;
extern int Slippage = 10;

int LastBars = 0;

int init(){return(0);}
int deinit() {return(0);}

This function defines lot size:

double GetLot(int Risk)
{double Free    =AccountFreeMargin();
 double One_Lot =MarketInfo(Symbol(),MODE_MARGINREQUIRED);
 double Min_Lot =MarketInfo(Symbol(),MODE_MINLOT);
 double Max_Lot =MarketInfo(Symbol(),MODE_MAXLOT);
 double Step    =MarketInfo(Symbol(),MODE_LOTSTEP);
 double Lot     =MathFloor(Free*Risk/100/One_Lot/Step)*Step;
 if(Lot<Min_Lot) Lot=Min_Lot;
 if(Lot>Max_Lot) Lot=Max_Lot;
 if(Lot*One_Lot>Free) {
 Alert(" free= ", AccountFreeMargin()," for one lot= ", MarketInfo(Symbol(),MODE_MARGINREQUIRED)," lot= ", Lot);
 return(0.0);}
return(Lot);}

We open an order here:

int NewOrder(int Cmd,double Lot)
{double TP=0; //takeprofit
 double SL=0; //stoploss
 double PR=0; //price
 color clr = CLR_NONE;
 while(!IsTradeAllowed()) Sleep(10);
 RefreshRates();
 if(Cmd==OP_BUY)
   {PR=Ask;
    if(TakeProfit>0) TP=Ask + Ask*TakeProfit/100;
    if(StopLoss>0) SL=Ask - Ask*StopLoss/100;
    if(SL<0) SL = 0;
    if(TP<0) TP = 0;
    clr = Green;}
 if(Cmd==OP_SELL)
   {PR=Bid;
    if(TakeProfit>0) TP=Bid - Bid*TakeProfit/100;
    if(StopLoss>0) SL=Bid + Bid*StopLoss/100;
    if(SL<0) SL = 0;
    if(TP<0) TP = 0;
    clr = Red;}
 int tic=OrderSend(Symbol(),Cmd,Lot,PR,Slippage,SL,TP,"",0,0,clr);
 if(tic<0) Print("Open order error: ",GetLastError());
return(tic);}

Here we close 1 or all orders

//CloseOrder
void CloseOrder()
{double PR=0;
 while(!IsTradeAllowed()) Sleep(10);
 RefreshRates();
 if(OrderType()==OP_BUY)  PR=Bid;
 if(OrderType()==OP_SELL) PR=Ask;
 if(!OrderClose(OrderTicket(),OrderLots(),PR,Slippage,CLR_NONE))
   Print("Order close error: ",GetLastError());
return;}

//Close all Orders
void CloseAllOrders()
{
  for(int i=OrdersTotal()-1;i>=0;i--)
   if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES))
     {
      CloseOrder();
     }
return;}

This function calculates the difference of two EMAs

double EmaDiff(int shift)
   {
      double difference;
      difference = iMA(Symbol(),0,FastEma,0,MODE_EMA,PRICE_CLOSE,shift)
                 - iMA(Symbol(),0,SlowEma,0,MODE_EMA,PRICE_CLOSE,shift);
      return(difference);
   }

And here is the body of the program

int start()
  {
double Lot;
    // действуем, когда открывается новая свечка
    if (LastBars == Bars) return(0);
    else LastBars = Bars;
      {         
         if ((EmaDiff(1) > 0) && (EmaDiff(2) < 0))
            {
               CloseAllOrders();
               Lot = GetLot(MaxRisk);
               NewOrder(OP_BUY,Lot);
            }
            
         if ((EmaDiff(2) > 0) && (EmaDiff(1) < 0))
            {
               CloseAllOrders();
               Lot = GetLot(MaxRisk);
               NewOrder(OP_SELL,Lot);
            }                    
      }
   return(0);
  }

I UNDERSTAND BUT THERE IS A LOT AND A PRICE AND A BUY OR SELL FOR EXAMPLE:

284429 2013-08-05 16:47:27 BUY 1.00 EURAUD 1.48839 0 628.85

THE PRICE IS 1.48839 CURRENCY PAIR -EURAUD, LOT 1 BROKER 5 MARK!!! PROFIT 628 I.E. THE PRICE WENT 628 PIPS UP!!! at lot 1!!! i mean if you can look at the history, i don't understand, honestly the time is almost 17:00 but the price is much lower than this 1.48839!!! EVEN IF THIS IS THE CLOSING PRICE I COUNTED 7000 PIPS I DO NOT UNDERSTAND HOW

Where did you count 7000 pips? It's the opening price, but even if it were the closing price, one price is not enough to count something there, you still need both of them. I think it's just a fake, unless the contest ran until December 18, when this position could have been closed with 630 pips profit. But before that he would have been forced to sit out a drawdown of about -830 pips (for 4zn), not very clever, the strategy is such a dismal guano...

I would have lost it on the real account, it works on a demo when I have a lot of virtual money)))

Please help me fix the errors in this function. It has already squeezed all the juice out of me. The essence of the function, when it reaches a certain profit, the function should close half of the order.

void CloseHalfOrder(){

for (int i = 0; i<=OrdersTotal(); i++)
{
if (OrderSelect (i,SELECT_BY_POS,MODE_TRADES) == true)
{
if (OrderSymbol() == Symbol() && OrderMagicNumber() == Magic && OrderProfit()>= NormalizeDouble (TP*Point,Digits))
{
if (OrderType() == OP_BUY)
double Lots = OrderLots();
double HalfLot = NormalizeDouble (Lots*0.5,2);
OrderClose(OrderTicket(),HalfLot,Bid,0,HotPink);

if (OrderType() == OP_SELL)
double Lots1 = OrderLots();
double HalfLot1 = NormalizeDouble (Lots*0.5,2);
OrderClose(OrderTicket(),HalfLot1,Ask,0,HotPink);
}
}
}
}

Oh, and how do I make this function work only once per open order?
