Quote from wrbtrader:
A computer outperforming a human is different than a computer trying to perform like a human.
Thus, a computer can outperform a discretionary trader but that doesn't imply that the computer can replicate or duplicate the thinking of a discretionary trader. Further, when markets change (it always changes)...both the computer and a discretionary trader must be able to adapt to remain profitable.
Quote from wrbtrader:
With that said, I have two friends that are futures brokers (one in Europe and one in US)...both say they've seen a decline in the number of new clients and the size of the average trading capital per client. In addition, I've seen LESS trade discussions along with LESS veteran traders at your active online forums.
Simply, I think scalping / day trading / swing trading / position trading or any other type of trading is on the decline regardless if its due to competition with computers or the global economic crisis...most likely due to both.

Quote from intradaybill:
I just picked this from the article:
"Stocks that once moved rather smoothly from point A to point B now move in a more jagged and less predictable manner. "
I trade for 25 years and I never remember of a time when anything, any market, traded smoothly from point A to point B.
This means that this article is making up premises in order to set up a straw man argument.
Daytrading is dead for those that use models that cannot compete in current environment. Trading in general never worked out well for the majority of traders anyway.
Quote from tradin4profits:
I daytrade nothing but stocks every day and do just fine with it, Anyone who says you cant daytrade stocks anymore just doesn't have a clue as to what they are doing.
