Quarb-X is a paper trading simulation platform. All trades use virtual capital ($10,000 by default) and have no real financial consequence. No real cryptocurrency is bought, sold, or transferred at any time. Any profit or loss displayed is hypothetical and for educational purposes only.

Past simulation performance does not guarantee future real-world results. Although Quarb-X models order latency and fills at the live order book, spreads that appear in simulation may not be executable in live trading due to: • High-frequency trading firms that close spreads within microseconds • Exchange withdrawal limits, network fees, and transfer delays • Order book depth beyond the top level and queue position • Regulatory restrictions in certain jurisdictions Quarb-X makes no representation that any strategy shown will be profitable in live trading.

Price comparisons between centralized exchanges (CEX) and decentralized exchanges (DEX) are for research and educational purposes only. In practice, CEX-DEX arbitrage requires: • Bridging assets between blockchains (15-30+ minutes) • Smart contract interactions with gas fees • Liquidity that may not exist at quoted price levels • Technical infrastructure beyond retail capability Do NOT attempt to replicate CEX-DEX signals from this platform with real funds.

Quarb-X uses machine learning — FinBERT sentiment on news headlines and statistical models that predict whether a spread will persist. These outputs: • Are not financial advice • May be inaccurate, poorly calibrated, or delayed • Are trained on simulated outcomes, not on real executions • Should not be the sole basis for any trading decision
