How to calculate cost per lot ?

New comment
 

Hello All,

I want to calculate the cost in account currency for 1 lot, so that I can now how much money I will lost/profit for 1 pip move. With this info then I can calculate in advance how much I will lost if stopped with stoploss, or how much I will profit if takeprofit is reached.

Any hint? I´ll code in an EA, so post code if possible.

Thanx.

Gero.

Look at these functions https://docs.mql4.com/account

and also MarketInfo(Symbol(),MODE_MARGINREQUIRED)

Good Luck

Thanx for your reply,

I´m using this function to calculate how much I´ll loss if all of my orders stop with StopLoss:

double CalculatePossibleLossOfMoney()
{
double oo = 0.0, // OrderOpenPrice
osl = 0.0, // OrderStopLoss
ol = 0.0, // OrderPossibleLoss in Pips
oml = 0.0, // OrderMaximumLoss in [Account Currency]
tml = 0.0, // total maximum loss if ALL OPEN ORDERS Stop with StopLoss
al = AccountLeverage(),
ls = 0.0; // LotSize
for( int i = 0; i < OrdersTotal(); i++ )
{
if( OrderSelect( i, SELECT_BY_POS ) )
if( OrderStopLoss() > 0 )
{
ls = MarketInfo( OrderSymbol(), MODE_LOTSIZE) * OrderLots();
oo = OrderOpenPrice();
osl = OrderStopLoss();
if( OrderType() == OP_BUY )
ol = oo - osl;
else ol = osl - oo;
oml = oo * ol * al * ls;
}
tml += oml;
}
return (tml);
}

So, I don´t know if it´s 100% OK, neither how to calculate this for Crosses, for example, etc...

Any help, suggestion are welcome.

 

This is exactly what you're looking for:

MarketInfo(Symbol(),MODE_TICKVALUE)

Thank you,

I need to use also ticksize, as you wrote here 'What is a TICK?' ? ie. TV * TS?

No, Phy and I pretty much came to the conclusion that you shouldn't need to use ticksize.

What you will need to do is to use a 10* multiplier for 3/5 digit brokers.


So for a 3/5 digit broker:

(MarketInfo(Symbol(),MODE_TICKVALUE) * 10 * Lots * StopLoss * 100) / AccountBalance()

will yield the risk of the transaction as a % of your balance.

Thank you,

I´m with a bug in the code somewhere, so I´ll try to correct then I´ll post the final code here, ok?

Very Thanx.

Well, I think we don´t need to correct for Point difference, int the code below If you modify OP_BUY with OP_SELL and OrderStopLoss() with OrderClosePrice(), you will have all current profits (or losses) and it returns the same result as in the Terminal Window, so I think it´s ok?

So here is the code:

double CalculatePossibleLossOfMoney()
{
double oo = 0.0, // OrderOpenPrice
osl = 0.0, // OrderStopLoss
ol = 0.0, // OrderPossibleLoss in Pips
oml = 0.0, // OrderMaximumLoss in [Account Currency]
tml = 0.0, // total maximum loss if ALL OPEN ORDERS Stop with StopLoss
// al = AccountLeverage(),
ls = 0.0, // LotSize
tv = 0.0; // Tick Value
// factor = 1.0; // For diff. in pip size

// if( Digits == 5 || Digits == 3 ) factor = 10.0;

for( int i = 0; i < OrdersTotal(); i++ )
{
if( OrderSelect( i, SELECT_BY_POS ) )
if( OrderStopLoss() > 0 )
{
ls = MarketInfo( OrderSymbol(), MODE_LOTSIZE) * OrderLots();
oo = OrderOpenPrice();
osl = OrderStopLoss();
tv = MarketInfo( OrderSymbol(), MODE_TICKVALUE );

if( OrderType() == OP_BUY )
ol = oo - osl;
else ol = osl - oo;
oml = tv * ol * ls;
}
tml += oml;
}
return(tml);
}

Yes, we have to account for Point size, and also use MarketInfo(OrderSymbol(), MODE_TICKSIZE), for example for crosses like pair GBPJPY, see new code:

double CalculatePossibleLossOfMoney()
  {
    double oo = 0.0, // OrderOpenPrice
           osl = 0.0, // OrderStopLoss
           ol = 0.0,  // OrderPossibleLoss in Pips
           oml = 0.0,  // OrderMaximumLoss in [Account Currency]
           tml = 0.0,  // total maximum loss if ALL OPEN ORDERS Stop with StopLoss
//           al = AccountLeverage(),
           ls = 0.0, // LotSize
           tv = 0.0, // Tick Value
           factor = 1.0; // For diff. in pip size
           
   if( Digits == 5 || Digits == 3 ) factor = 10.0;
           
    for( int i = 0; i < OrdersTotal(); i++ )
      {
        if( OrderSelect( i, SELECT_BY_POS ) )
          if( OrderStopLoss() > 0 )
            {
              ls = MarketInfo( OrderSymbol(), MODE_LOTSIZE) * OrderLots();
              oo = OrderOpenPrice();
              osl = OrderStopLoss();
              tv = MarketInfo( OrderSymbol(), MODE_TICKVALUE ) * MarketInfo( Symbol(), MODE_TICKSIZE);            
              
              if( OrderType() == OP_BUY )
                ol = oo - osl;
              else ol = osl - oo;
              oml = tv * ol * ls * factor;
            }
        tml += oml;
      }
      return(tml);
  }

Any comment?

Oops, some times TICKSIZE = 0, so below is the corrected code:

double CalculatePossibleLossOfMoney()
  {
    double oo = 0.0, // OrderOpenPrice
           osl = 0.0, // OrderStopLoss
           ol = 0.0,  // OrderPossibleLoss in Pips
           oml = 0.0,  // OrderMaximumLoss in [Account Currency]
           tml = 0.0,  // total maximum loss if ALL OPEN ORDERS Stop with StopLoss
           ls = 0.0, // LotSize
           tv = 0.0, // Tick Value
           ts = 0.0, // Tick Size           
           factor = 1.0; // For diff. in pip size
           
    if( Digits == 5 || Digits == 3 ) factor = 10.0;
           
    for( int i = 0; i < OrdersTotal(); i++ )
      {
        if( OrderSelect( i, SELECT_BY_POS ) )
          if( OrderStopLoss() > 0 )
            {
              ls = MarketInfo( OrderSymbol(), MODE_LOTSIZE) * OrderLots();
              oo = OrderOpenPrice();
              osl = OrderStopLoss();
              tv = MarketInfo( OrderSymbol(), MODE_TICKVALUE );
              ts = MarketInfo( OrderSymbol(), MODE_TICKSIZE );
              if( ts > 0 ) tv *= ts;
              
              if( OrderType() == OP_BUY )
                ol = oo - osl;
              else ol = osl - oo;
              oml = tv * ol * ls * factor;
            }
        tml += oml;
      }
      return(tml);
  }
