Hey Product Hunt 👋 I'm the maker. I built this because I was scalping BTC/ETH on 1-min bars and bleeding to fees, and I couldn't tell if my signals were bad or the market was bad. Every existing backtester I tried either required an account, wanted a payment, or assumed I was running a 4-hour swing trade. This is the thing I wanted: a single static page where I add a real position, click "Scalp", and see what would have happened. The backtester simulates a 0.2% round-trip fee and flags days where the intraday range is <1.5%. A few things I'd love feedback on: 1. The signal logic itself (pivot + volume spike). Is there something smarter that works for 1-min? 2. The data source. Right now only Binance's free REST API. Should I add Bybit / OKX? 3. The replay UX. Right now signals pop on the chart in real time. Should they pre-paint with a "would have been this" tooltip? Free, no signup, no analytics that track you personally. Would love to hear what you think. — The maker
