Hi i'm new What are the advantages/disadvantages of putting orders through ECNs, REDI plus, thru a trade desk, calling down to the trading floor? I heard a trader say he prefers redi plus to ecns but he would like access to a trade desk or be able to call down to the floor? isnt it all the same?
You must first know the difference between listed stocks and OTC (over-the-counter) Listed stocks traditionally traded on exchange floors - calling the order down. These are stocks with 3 or less symbols. (They can be traded on ECNs or with market makers as well.) OTC stocks have more than 3 letters. These do not have a centralized exchange. ECNs and market makers are the tools for execution. ECNs display orders and mtch them electronically. Market Makers trade to make money.
