Sizing drills
Practice: $2,000 account, 1% risk, 25-pip stop, pair at ~$10/pip per lot. Risk = $20; per-lot risk = 25×$10 = $250; size = 20/250 = 0.08 lot. Do ten of these until instant. If you cannot size a trade in seconds, you are not ready to risk real money. The ShaFX calculator does it, but you must understand it.
