Options are different than outrights. Even electronically traded options there is still a lot of chat and voice
What are you talking about?
Outright? What does that mean? Are you referring to the underlying security or index of an option?
And what do you mean by voice and chat?
The simple fact is that most trades of stock, options, and futures are now processd through electronic platforms that do not involve one person talking to another, whether by voice, text, e-mail, or anything else. That doesn't mean there is no human involvement. Market makers and other industry professionals enter bids and offers into electronic systems. But most trading does not involve voice or text communication.
