Lot size isn't a guess: it comes from how much money you accept to lose if price hits your stop.
EURUSD example: $1,000 account, 1% risk ($10), 20-pip stop. With 1 lot each pip is worth $10, so:
If the stop is hit you lose $10, not a dollar more, whatever your leverage.
FAQ
How much is a pip worth with 1 lot?
On pairs quoted in USD (EURUSD, GBPUSD, AUDUSD, NZDUSD) 1 pip with 1 standard lot is worth $10; with 0.01 lots, $0.10. On USDJPY, USDCAD or USDCHF it depends on the pair's price — that's why the calculator asks for it.
How much is 1 lot of gold (XAUUSD)?
With most brokers 1 lot of gold is 100 ounces: every $1 the price moves is $100 with 1 lot and $1 with 0.01. On gold the stop is measured in dollars of price: entry at 2,400 and stop at 2,395 is $5.
What is contract size and where do I find it?
It's how many units are in 1 lot: 100,000 in forex, 100 ounces in gold, 5,000 in silver, 1 BTC in Bitcoin. In MT5: right-click the symbol → Specification → "Contract size".
How much should I risk per trade?
Most professional and funded-account traders risk 0.5% to 1% per trade. At 5%, five losses in a row (which is normal) take almost a quarter of your account.
