What is the Bid-Ask Spread and how is it determined in crypto markets?

The bid-ask spread is the gap between the highest buyer bid and lowest seller ask. It's driven by order book depth, volume, and market-maker competition - tighter on liquid pairs like BTC, wider on low-cap altcoins.

What is slippage in cryptocurrency trading and why does it occur?

Slippage is the difference between expected and actual fill price. It occurs when large orders consume multiple book levels, or when prices shift between submission and execution - worsening significantly during low liquidity or high volatility.

What is the difference between positive slippage and negative slippage?

Negative slippage means filling at a worse price than expected; positive slippage means filling better. Negative slippage is far more common, especially for large market orders in thin or fast-moving markets.

How do market makers influence the Bid-Ask Spread and liquidity in crypto markets?

Market makers post continuous bids and asks, earning the spread while deepening order books. Their presence tightens spreads and reduces slippage. On Delta Exchange, active market makers on perpetuals and options are critical for fair mark pricing and efficient execution.

What are the best strategies to minimize slippage when trading cryptocurrencies?

Use limit orders over market orders, split large trades into tranches via TWAP/VWAP, and trade during peak-volume sessions. Prioritise exchanges with deep liquidity - BTC and ETH perpetuals inherently carry lower slippage than illiquid altcoin spot markets.
