Post subject:  Calculate break even for a basket?
Hello guru-coders :)

Does anyone have a code-snippet to calculate a basket break even price (1..n buy/sell trades with different lot sizes, including commissions and swap)?

I'm not good enough at maths to figure it out... :oops:

Any help is highly appreciated!

Best Regards,
Andy

Hope this helps - attached working indicator as proof of concept

Code: Select all

int    nOrders       = 0;
   double dOpenPrice    = 0.0;
   double dProfit       = 0.0;
   
   for (int i = 0; i <= OrdersTotal(); i++) 
   { 
      if(OrderSelect(i,SELECT_BY_POS))
      { 
         if(OrderSymbol() == Symbol())
         {
            if(OrderType() == OP_BUY || OrderType() == OP_SELL)
            { 
               dOpenPrice += OrderOpenPrice();
               dProfit+= OrderProfit() + OrderSwap();
               nOrders++;
            }
         } 
      }
   }   
   
   if(nOrders > 0)
   {
      double dAvgEntryPrice = dOpenPrice/nOrders;

Hey mobthehop,

Thanks for the speedy reply.

I went through your code, and some questions remain:

Code: Select all

dProfit+= OrderProfit() + OrderSwap();
Why are you summing up profits and don't make any further reference/use to/of it?

Furthermore, I don't see, how different lot size of the individual trades are taken into account? Or am I missing something complete here?

Cheers,
Andy

   if(nOrders > 0)
   {
      double dAvgEntryPrice = dOpenPrice/nOrders;

Hi Andy, mmhhh...... Please have a look at the complete code in indicator

a) dProfit is used to draw the profit / loss rectangle on chart....
b) different lot sizes are considered with OrderProfit()

Think of it more of a hint how to do it, I hacked this up 2 years ago to visually represent open PL of baskets, probably not 100% what you need

Cheers

I don't do any basket trading, so this may be a stupid question, but the heck is a break even "price" for an entire basket?

Hi,

// Global
extern bool useAverageBE = false; // Use average breakeven closure.

//Put in start
if (RunningTrades(Symbol()) > 1 && useAverageBE && countProfit(Symbol()) <= 0)
{
CloseTrades(Symbol(), 10, MagicNumber);
Alert("Orders, ", symbol, ", closed at breakeven.");

}

int RunningTrades(string symbol)
{
int trades = 0;
for (int i = 0; i < OrdersTotal(); i++)
{
if (!OrderSelect(i, SELECT_BY_POS, MODE_TRADES))
continue;
if (OrderMagicNumber() == MagicNumber && OrderSymbol() == symbol && OrderType() == OP_BUY || OrderType() == OP_SELL)
{
trades++;
}
}
return(trades);
}

//+------------------------------------------------------------------+
//| expert Get profit/loss for all trades for this symbol function
//+------------------------------------------------------------------+
double countProfit(string symbol)
{
double cash = 0;

for (int i = 0; i < OrdersTotal(); i++)
{
if (OrderSelect(i, SELECT_BY_POS, MODE_TRADES))
if ((OrderSymbol() == symbol) && OrderMagicNumber() == MagicNumber)
{
cash += (OrderProfit() + OrderSwap() + OrderCommission());
}
}
return(cash);
}



//+------------------------------------------------------------------+

void CloseTrades(string symbol, int Slippage, int MagicNumber)
{
bool closed = false;
for (int i = OrdersTotal(); i >= 0; i--)
{
OrderSelect(i, SELECT_BY_POS, MODE_TRADES);
while (IsTradeContextBusy())
Sleep(100);
RefreshRates();
if (OrderType() == OP_BUY && (MagicNumber == OrderMagicNumber() && OrderSymbol() == symbol))
{
closed = OrderClose(OrderTicket(), OrderLots(),
NormalizeDouble(MarketInfo(OrderSymbol(), MODE_BID), MarketInfo(OrderSymbol(), MODE_DIGITS)), Slippage, CLR_NONE);
refreshGrid();
}
if (OrderType() == OP_SELL && (MagicNumber == OrderMagicNumber() && OrderSymbol() == symbol))
{
closed = OrderClose(OrderTicket(), OrderLots(),

}
