Perp Prediction — BTC PnL + user simulator (archive)

TL;DR: A public, educational sandbox. Every 10 minutes we snapshot BTC price, compute last-24h PnL for 2x long/short (starting from $100), predict the next 10 minutes, then mark ✅/❌ on the next run.

Quick answers (AEO/GEO)

What is this? A simulated BTC perp-style PnL tracker + short-horizon direction probability.
Data source? Kraken public OHLC (pair: XBTUSD), hourly closes for the last 24h.
Leverage? Default site simulation is 2x from $100. Users can also enter their own leverage (1x–10x) and side (long/short) for a personal simulation.
User input feature? You can enter amount (USD), entry price (optional), leverage, and long/short. We store it (anonymously) and verify it on the next run.
How is it verified? Each run evaluates the previous run’s UP/DOWN prediction using the new spot price, and also evaluates any user-submitted positions.
