Could you build this?

Partial The candle-replay UI, position tracking, and R/win-rate stats are straightforward to vibe-code in a browser. Clean, licensed historical intraday data for EUR/USD, GBP/USD, gold, DXY, and DAX is the harder piece.

What it would actually take: Use a charting library (e.g., TradingView Lightweight Charts) with a React or Svelte front end and a simple backend for trade logging and social battles. The hard part is sourcing accurate, tick- or minute-level historical OHLC data across several instruments, either through a licensed vendor such as Dukascopy, Polygon, or a broker feed, or by curating public datasets and handling their gaps and licensing terms. Some market-data literacy is needed to avoid misleading replays.
