I built free position-size calculators for forex traders — the lot-size math most beginners get wrong

dev.to Beginners2026-10-15 02:230 views

Lot size decides everything: risk per trade, pip value, how fast an account dies. Most beginners eyeball it. The math is simple — risk amount ÷ (stop-loss in pips × pip value) — but it changes per pair, per account currency, per contract size. So I built PipAtlas: free, no-signup calculators for BTCUSD, NAS100, XAUUSD and majors, plus a pip calculator and a glossary. No ads, no email wall. Feedback welcome — what would you add?
