Hey Product Hunt 👋 I built Hex37 because every crypto paper trading sim I tried taught the wrong habits. Most fill every order at mid-price, skip funding, never simulate a liquidation. Traders practise on those, go live, and the first time slippage and funding show up, they show up with real money. Hex37 is the lab I wanted: live Binance market data, realistic slippage (0.05–0.2%), partial fills, perpetual funding every 8h on real rates, liquidations at 1% maintenance margin with the forced-close costs a real exchange charges. Free Forever tier with $10,000 in virtual USDT. No card. No KYC. The Pro tier adds AI critique on every closed trade and unlimited alerts. Three things I'd love feedback on: - Does the execution feel realistic vs. what you've used? (Be brutal.) - The journal auto-logs R-multiples — useful or noise? - Anything you'd want a paper trading platform to do that nothing on the market does today?
