A free browser tool for crypto traders who scalp on 1-minute bars. Add a position, click Scalp, and it pulls live 1-min data from Binance's public API, computes VWAP support/resistance from intraday pivots, and replays every buy/sell signal with a realistic 0.2% round-trip fee subtracted. No signup, no server — positions live in your browser. Built because I was losing $800 over 6 months to fees on "feels right" entries.
