Market Making vs Market Taking (Quotes vs Orders)
This is too lengthy for a comment. The following quoted passages are excerpted from this Money SE post. Before electronic trading and HFTs specifically, trading was thin and   onerous. No. The NYSE and AMEX were deep, liquid and transparent for nearly 75 years prior to high frequency trading (HFT), in 2000 or so. The same is true for NASDAQ, but not for as many years, as NASDAQ is newer, being an electronic market. The point is that it existed, and thrived, prior to HFT. The NASDAQ can be active and functional, WITH or WITHOUT high frequency trading.  This is not historically true, nor is it true now:  Without a bid or ask at any given time, there could be no trade... Market makers, also known as specialists, were responsible for hitting the bid and taking the offer on whatever security they covered. They had a responsibility assigned to them by the exchange. Yes, it was lucrative! There was risk, and they were rewarded for bearing it. There is a trade-off though. Specialists provided greater stability on a systemic level, although other market participants paid for that cost. Prior to HFT, traders who were not market makers were often bounded by, boxed in, by the toll paid to market makers. Market makers had different, much higher capital and solvency requirements than other traders. Most specialists/market makers had seats, or shared a seat on the NYSE or AMEX. Remember that market makers/specialists are specific to stock markets, whereas HFT is not. If this is true, then we are in trouble: HFTs have supplanted the traditional market maker Why? Because trading volume is LOWER now than it was in the 1990's! EDIT In the comments, I noticed that OP was asking about the difference between  I suggest reading this very accurate, well-written answer to a related question, The spread goes to the market maker, is the market maker the exchange? That explains the difference between
