Need help in calculating profit/loss

Pair: EURUSD
Size: .50
Price (sell): 1.3407
Closed: 1.3380
Profit: 30 Pips or $135

The equation:

Sold Price (- minus) Current Price = Total A (won/loss)

Total A (/ divide) Current Price = Total B

My question is how do i get to Total B ($135) or find out what is the current price at that time?

thnks

Those are very strange equations.
Your profit/loss in pips is really Sold Price (- minus) Current Price = Total A (it's 27 pips in your case by the way).

If by Total И you mean the amount in USD which you get, you just have to multiply it by the amount currency units in your position:

0.5 lot is 50,000 units

27 pips = 0.0027

0.0027 * 50,000 = 135 (USD)

The simple rule is that 1 pip = $10 with 1 lot positions. So, with 0.5 lot it's $5. Then you can just multiply the number of profit/loss pips by $5.

thnks..

got it
