How do you calculate position size in trading?+
Size (lots) = (account × risk %) ÷ (stop loss in pips × pip value per lot). Example: 10,000 at 1% risk with a 20-pip stop and 10/pip → 100 ÷ 200 = 0.5 lot.
What percentage should I risk per trade?+
Most professional traders risk between 0.5% and 2% of their account per trade. 1% is the most common standard.
What is the value of a pip?+
For 1 standard lot (100,000 units) on USD-quoted pairs, one pip is worth about $10. For JPY pairs and other quote currencies the value varies slightly.
