Explanation:

The bid-ask spread is best explained as the difference between the bidding price and the asking price.

Let’s say that I’m looking to buy a security at the bidding price of $10 and the asking price is $10.50 if I it’s me that wants the security immediately, I'm going to have to pay the asking price not the bidding price, on the other hand if it’s the dealer who wants to sell instantly and immediately they're going to have to be paying the bidding price. The bid-ask spread of that basically is the 50 cent difference.
