I think this question is actually fairly interesting. As most of us probably know, behavioral finance drives profits and at the same time misfortunes for many. Algorithmic trading is pretty systematic and will obey the rules regardless of what the person who programmed it thinks (therefore, it may avoid the mistakes a person will make with irrational behavior).

Around 60% of today's trading is actually done automatically using similar systems (computerized) sometimes done with softwares from brokerages.

My personal opinion is that it will become more and more competitive as people will be building algorithms to trade vs other firms and people. If everyone's systems are similar then it would be difficult to for many to live off (generate a profit) off the markets.

I am also interested in what many of you think! Please reply!
