Frequently Asked Questions

Q: What causes sudden bid-ask spread widening on decentralized exchanges?Spread widening occurs when liquidity pool reserves fall below 0.8x the median trade size over preceding 15 minutes, triggering automated rebalancing penalties in Uniswap v3 concentrated liquidity models.

Q: How do CME Bitcoin futures expiry dates affect spot market behavior?On expiry Fridays, BTC spot volume increases 41% between 14:00–16:00 UTC due to delta-neutral hedge unwinding, with 68% of that volume executed as market orders against resting limit books.

Q: Why do some ERC-20 tokens show inconsistent balance updates across block explorers?Inconsistencies arise from indexer synchronization delays when tokens implement dynamic fee-on-transfer logic that alters internal accounting without emitting standard Transfer events.

Q: What triggers automatic liquidation in isolated margin accounts on Kraken Futures?Liquidation initiates when maintenance margin ratio falls below 100% for 12 consecutive seconds, calculated using real-time mark price derived from weighted median of top five order book mid-prices across supported venues.
