Calculator FAQs
How do I calculate my position size in forex?
Decide how much of your account you are willing to risk on the trade (many traders use 1–2%), then divide that risk amount by your stop-loss distance in pips multiplied by the pip value of one lot. The position size calculator above does this for you: enter your balance, risk percentage, stop-loss and instrument, and it returns the size in lots and units.
What is a pip and how much is it worth?
A pip is the standard unit of price movement in forex — 0.0001 for most currency pairs and 0.01 for yen pairs. Its cash value depends on the instrument, your trade size and the current exchange rate. For one standard lot of EUR/USD a pip is worth 10 US dollars; use the pip value calculator for any other instrument or size.
How much margin do I need to open a trade?
Margin is your position's full notional value divided by your account leverage. For example, one lot of EUR/USD at 1.1000 has a notional value of 110,000 US dollars; at 1:100 leverage the required margin is 1,100 US dollars. The margin calculator applies the live rate and your chosen leverage automatically.
