Hi Product Hunt! 👋 I’m incredibly excited to share FinCalc Edge with you today. The Problem: As a day trader, I kept running into the exact same frustrating issue during fast market breakouts (especially on volatile assets like Gold). By the time I loaded up a clunky, ad-heavy risk calculator and typed in my stop loss to figure out my proper lot size, the entry was already gone. When I tried to skip the math and just "guess" my size to enter faster, I’d inevitably risk way more of my funded account than my strict 1% rule allowed. The Solution: I realized traders need execution speed, not server lag. So, I built FinCalc Edge. It’s a 100% free, zero-latency position size and risk management calculator designed for active day traders. The Approach: I built the architecture using Next.js with entirely client-side mathematics. This means the second you adjust your risk percentage slider or type your stop-loss distance, your exact lot size and value-at-risk update instantly. No page reloads, no server pinging, no waiting. Just instant math so you can execute your trade without hesitation. It currently supports Forex, Crypto, Metals, and Indices. I would absolutely love to hear your feedback! For the traders out there: what other specific risk metrics or asset classes would you want to see added to the tool next? I'll be hanging out in the comments all day to answer questions!
