In the attached image, you can see trades 2 to 26. Column D (Price Yellow) shows the opening price and Column J (Price Yellow) shows the close price.
What I don't understand is why is the Profit column NOT equal to the difference between the opening and closing prices? Column M, shows the calculated differences between the 2 prices and (I thought) should match up to the Profit/Loss but it doesn't. The lot size was the same (1) for all trades also. What's curious is that the results are as expected in trades 21 to 26 but all the others are off.
Am I missing something here or what?
