Let's assume i wanna open a SELL order.
Before i send the OrderSend i calculate that my TP and SL shall be 100 pips from BID
And then i send the order, something like this:
So to the question:
In this case, will the TP/SL always be exactly 100 pips from OrderOpenPrice() becuase BID before the order opens and OrderOpenPrice() of order is always equal?
Or can the OrderOpenPrice() move away from current BID in the time between and OrderSend and the actual opening of order?
It's called slippage.
