Partial The replay UI, hidden-future chart, and paper-trading journal are straightforward to vibe-code. Accurate historical perp data with funding rates and an exchange-faithful liquidation engine are harder to get and get right.
What it would actually take: Build a charting frontend on top of a candle store, with a simulation engine that advances one bar at a time and tracks positions, margin, funding and liquidation. The hard parts are sourcing clean historical perp data (funding, mark prices, order book depth for realistic fills) and matching exchange liquidation rules. This needs a quant or trading-systems engineer to validate the simulation.
