The Bid/Ask Spread. The bid/ask spread is the difference in price between the bid and ask. In active stocks the bid/ask spread is typically $0.01, for example the bid is $10.05 and the offer is $10.06. The attached chart example shows a Level 2 in the SPDR S&P 500 ETF.
The difference between the ask price and bid price is called the spread, and it is similar to what you see in the stock market. Essentially, the spread is the cost of trading, or in the case of Precious Metals, buying and selling.
