Could you build this?

Partial The replay chart UI, footprint and volume profile views, and trade analytics are vibe-codeable. Candle-by-candle historical data across 38 markets and rule sets for 99 prop firms need licensed, high-quality data and ongoing curation.

What it would actually take: The stack would be a charting library, a replay engine that streams historical candles, and a database of rules for prop firms. The hard part is data: licensed tick or minute-level historical data for many markets is expensive, and footprint charts need order-flow data. Accurate prop firm modes also need someone to keep track of changing rules, and the data licensing costs and ongoing curation are where a solo builder would struggle.
