How the calculation works
Every good trade starts with the loss, not the profit. You decide the maximum you are happy to lose, then size the position so that hitting your stop loss costs exactly that amount.
- Risk amount = balance × risk %. With 1,000 and 1%, that is 10.
- Stop distance = the gap between entry and stop loss. 4310 to 4072 is 238.
- Loss per 1 lot = stop distance × contract size × conversion rate.
- Lot size = risk amount ÷ loss per 1 lot, rounded down to your broker's lot step so you never risk more than planned.
Targets use risk : reward. At 1 : 2 the target sits twice your stop distance away from entry, so if it hits you make twice what you risked. You can add up to 10 targets, or switch to Price and type your own target prices to see the risk : reward of each one. Profit shown for each target assumes the full position is closed there.
If the smallest lot your broker allows already risks more than your limit, the calculator tells you. The honest answer in that case is a wider account, a tighter stop, or skipping the trade.
Stocks work differently. There you choose how much of your balance to put into the trade. Shares = (balance × % to invest) ÷ entry price, rounded down to whole shares. With 1,000 and 10% at 10 a share, that is 10 shares. The stop loss and targets then show how much that holding would lose or make.
For learning and planning only. This is not financial advice. Contract sizes, lot steps, margin and leverage differ by broker and symbol, so confirm them in your own trading platform before placing any order. Spreads, commissions and slippage can make the real loss slightly bigger than shown.
