PIP price per position

[veedoo]

Hi,

I'm trying to calculate one PIP price for closed position, and then calculate position profit, but results I'm getting always differ from OrderProfit(). Please help me correct my code.
By PIP I always mean 1/10000 LOT price (even if there is 5 digits precision), I'm testing it in Strategy Tester on GBPUSD, account currency is set to GBP (to avoid currency rates) and I set spread for 20 (which is 2 PIP for my code):

double p = 10 * Point(); // for 5 digits precision
double lot_price = AccountLeverage() * MarketInfo(Symbol(), MODE_MARGINREQUIRED);
double pip_price = lot_price * OrderLots() * p;
double spread = 2 * p;

int dir = 0;
switch(OrderType()) {
    case OP_BUY: case OP_BUYLIMIT: case OP_BUYSTOP: dir = 1; break;
    case OP_SELL: case OP_SELLLIMIT: case OP_SELLSTOP: dir = -1; break;
}

double res = (dir * (OrderClosePrice() - OrderOpenPrice()) - spread) / p;

string str = StringFormat("%6.2lf x %4.2lf = %6.2lf (%6.2lf)\n", res, pip_price, res * pip_price, OrderProfit());
Print(str);

Exmaple output (OrderLots() == 0.02):

 50.00 x 0.20 =  10.00 (  5.74)
 29.00 x 0.20 =   5.80 (  3.42)
 18.00 x 0.20 =   3.60 (  2.21)
  9.00 x 0.20 =   1.80 (  1.21)
-38.00 x 0.20 =  -7.60 ( -3.97)
-39.00 x 0.20 =  -7.80 ( -4.08)

There is no such thing as PIP price or LOT price. There is only a change in price, lots size, and value of the currency per point. The latter depends on the pair and the account currency's exchange rates.

• You place the stop where it needs to be - where the reason for the trade is no longer valid. E.g. trading a support bounce the stop goes below the support.
• Account Balance * percent/100 = RISK = OrderLots * (|OrderOpenPrice - OrderStopLoss| * DeltaPerLot + CommissionPerLot) (Note OOP-OSL includes the SPREAD, and DeltaPerLot is usually around $10/pip)
• Do NOT use TickValue by itself - DeltaPerLot
• You must normalize lots properly and check against min and max.
  
• You must also check FreeMargin to avoid stop out
