Good day/night

I am trying to reverse a trade using this primitive method which does not work (the calculation in the Expert Advisor is based on ticks):

if(CalculateCurrentOrders(Symbol())>0 && Close[1]<LowLevel) // determines if there were buy orders && if a candle closed below the lower level

{

CheckForClose(); // close the order

OpenSell(); // open a sell order

return;

}

Please advise where I am going wrong? I would also be grateful for links that would allow me to close this gap.

in this function you probably count all orders.
 

How do I determine how many minutes there are between Time1 and Time2?

datetime Time_1     = D'2011.01.12 13:30';
datetime Time_2     = D'2011.01.05 10:30'; 

минут = Time_1- Time_2
 
sergeev:
this is probably the function where you count all orders. this should be Buy

This is a standard function:

int CalculateCurrentOrders(string symbol)
{
int buys=0,sells=0;
for(int i=0;i<OrdersTotal();i++)
{
if(OrderSelect(i,SELECT_BY_POS,MODE_TRADES)==false) break;
if(OrderSymbol()==Symbol() && OrderMagicNumber()==MAGICMA)
{
if(OrderType()==OP_BUY) buys++;
if(OrderType()==OP_SELL) sells++;
}
}

if(buys>0) return(buys);
else return(-sells);

}

if >0 then it is a buy order, if <0 then it is a sell order ))))

the difference returns the number of seconds.

divide by 60. you get the number of minutes.

 
Reverse the transaction. Changed the structure of the Expert Advisor - removed the functions. How to make it close and open on one candle under certain conditions.

extern double TP = 70; //takeprofit
extern double SL = 0; //stoploss
extern double Lot = 0.1;

double HighLevel;
double LowLevel;
int resBuy=0;
int resSell=0;


//+------------------------------------------------------------------+
//| expert initialization function |
//+------------------------------------------------------------------+
int init()
{
HighLevel=High[1];
LowLevel=Low[1];
return;
}

//+------------------------------------------------------------------+
//| expert function |
//+------------------------------------------------------------------+

void start()
{

if(Bars<100 && IsTradeAllowed()==false) return;


if(resBuy==0 && resSell==0 && CheckBreak()==-1)
{
resSell=OrderSend(Symbol(),OP_SELL,Lot,Bid,2,0,Bid -TP,"",MAGICMA,0,Red);
HighLevel=LowLevel;
LowLevel=Close[1];
return;
}

if(resBuy==0 && resSell==0 && CheckBreak()==-1& CheckBreak()==1)
{
resBuy=OrderSend(Symbol(),OP_BUY,Lot,Ask,2,0,Ask + TP,"",MAGICMA,0,Blue);
LowLevel=HighLevel;
HighLevel=Close[1];
return;
}

if(resBuy!=0 && resSell==0 && Close[1]<LowLevel) //------------------------------------- interested in this part: closing and opening on one bar
{
bool closeBuy=OrderClose(resBuy, Lot, Bid, 2, Blue);
// while(!IsTradeAllowed()) Sleep(100);
resSell=OrderSend(Symbol(),OP_SELL,Lot,Bid,2,0,Bid -TP,"",MAGICMA,0,Red);
HighLevel=LowLevel;
LowLevel=Close[1];
return;
}

if(resSell!=0 && resBuy==0 && Close[1]>HighLevel) //------------------------------------- interested in this part: closing and opening on one bar
{
bool closeSell=OrderClose(resSell, Lot, Ask, 0.0002, Red);
// while(!IsTradeAllowed()) Sleep(100);
resBuy=OrderSend(Symbol(),OP_BUY,Lot,Ask,2,0,Ask + TP,"",MAGICMA,0,Blue);
LowLevel=HighLevel;
HighLevel=Close[1];
return;
}

}

//----------------------------------------------------------------- Check Low&High break (Func)

double CheckBreak()
{
double candle=Open[1]-Close[1];

if(candle>0 && Low[1]<LowLevel) return(-1);
if(candle<0 && High[1]>HighLevel) return(1);
}

divide by 60. it gives the number of minutes.

I just get the date 1971.03.04 12:00, maybe this needs to be converted?

extern datetime Time_1     = D'2011.01.12 13:30'; 
extern datetime Time_2     = D'2011.01.05 10:30'; 

bool   Commentari      = true;

int start()
  {

if (Commentari){
 Comment(
         "\n Дата  =  " + TimeToStr((Time_1-Time_2)/60)," минут",
      
         "\n==============================");}
   return(0);
  }
 
Eliza:

First of all, why are you multiplying by 60?

Second - if you want to display the number of minutes as a time like 00:15,
you don't have to divide or multiply by 60.

 
sergeev:

First of all, why are you multiplying by 60?

Secondly - if you want to represent the number of minutes on the screen as a time like 00:15,
there's no need to divide or multiply by 60.

Yes, I corrected for division, but the year comes out 1970.01.01 02:51

I don't need it for the screen, I just wanted to find the number of minutes without dates, for that time interval....

even without dividing, it still outputs the date, or should I subtract the date from which the function is based on?

  • datetime is date and time, an unsigned integer that contains the number of seconds elapsed since 0 hours of January 1, 1970. 
  • extern datetime Time_1     = D'2011.01.12 13:30'; 
extern datetime Time_2     = D'2011.01.05 10:30'; 

datetime me_2     = D'1970.01.01 00:00'; 

bool   Commentari      = true;

int start()
  {

if (Commentari){
 Comment(
         "\n Дата  =  " + TimeToStr(me_2-(Time_1-Time_2))," минут",
      
         "\n==============================");}
   return(0);
  }

  • if i subtract the date 1970.01.01 02:51 it throws out that invalid time, i just need the number of minutes to get from this time interval, if its for example 25000 minutes in this interval i need this number 25000 ... something like that(
  • or is it not possible to get this by the μl language?
 

If you just want a number of minutes, you have absolutely no reason to use TimeToStr

Time is a normal int number.

Or alternatively, use TimeToStr only with TIME_MINUTE flag
