A lot is the unit of size of a trade. In forex, 1 standard lot is 100,000 units of the base currency; 0.10 is a mini lot and 0.01 a micro lot. In gold, 1 lot is usually 100 ounces.
Choosing the right lot size is what turns a stop loss into a controlled loss. If your stop is 50 pips away and you want to risk $100, you need each pip to be worth $2: on EURUSD, 0.20 lots.
The formula is always the same: lots = risk ÷ (stop distance × value per lot). The calculator applies it with each instrument’s contract size and converts to your account currency.
Lots = money you risk ÷ (stop distance × value per lot). For example, to risk $100 on EURUSD with a 20-pip stop: each pip is worth $10 per lot, the stop costs $200 per lot and 100 ÷ 200 = 0.50 lots. The result is rounded down so you never go over your risk.
It is the unit of size of a trade. In forex, 1 standard lot is 100,000 units of the base currency, 0.10 is a mini lot and 0.01 a micro lot. In gold, 1 lot is usually 100 ounces; in indices and crypto it depends on the broker.
It is a personal decision, but the most common reference is 1% of the account per trade, and many prop firm traders use 0.5% to 1% because firms cap the daily loss at 3–5%. The calculator warns you above 3%.
For three reasons: your broker may use a different contract size or minimum lot (change them in “Broker settings”), it converts currencies at its real-time price instead of the ECB daily rate, and the spread and commissions add to the real loss.
