What is bid size and ask size in wealth simple?
I'm new to wealthsimple app and wanted to know what some numbers mean. If we look at Microsoft stock for example and look at these numbers shown in the app:  Bid $259.87 x 17,481 Ask $259.90 x 10,387 Last sale $259.89 x 0  I know the bid price represents the maximum price that a buyer is willing to pay for a share of stock or other security. The ask price represents the minimum price that a seller is willing to take for that same security. And Last sale is the price of the last transaction some trader did. I think it relates to the bid/ask size, but not entirely sure. Thanks
