The order book: bid, ask, spread
Everything starts with the order book: the list of every resting limit order, sorted by price. Two sides face each other at all times.
- Bid: the resting buyers, offering to buy at a given price or lower. The best bid is the highest buying price.
- Ask (or offer): the resting sellers, offering to sell at a given price or higher. The best ask is the lowest selling price.
- Spread: the distance, in ticks, between the best bid and the best ask. Tight spread, liquid market; widening spread, thin liquidity or volatility.
