Educational content, not investment advice. Nour explains how markets work. She never tells you what to buy or sell.
A lot is a standard unit of trade size; the platform's contract size tells you how many units one lot holds.
- In forex one lot is commonly 100,000 units of the base currency. Standard 1.00 = 100,000 (≈$10/pip on EUR/USD), Mini 0.10 = 10,000 (≈$1), Micro 0.01 = 1,000 (≈$0.10).
- A 50-pip loss on a $1,000 account: −$500, −$50 or −$5.
- Minimum volume and volume step are set by the broker — check the symbol specification.
- Size is a result: risk amount ÷ (stop pips × pip value). $10 ÷ 25 pips = $0.40/pip = 0.04 lot.
