Trading volume records market activity but cannot, by itself, indicate quote quality or whether trades can execute smoothly. According to ChainCatcher, venues with similar volumes may have different market conditions because of differences in bid-ask spreads, order-book depth and individual trade sizes. Spreads and depth should be assessed using consistent asset versions, quote currencies, price ranges, sampling times and calculation methods; visible order-book depth reflects only displayed orders, not all available liquidity. Tracking comparable data over time can reveal verifiable changes, while a wide spread alone is not a definitive risk conclusion.
