Quote from boid-dog:
i know one who's traded in the pit w/ Baldwin & co. Ask him how he trades--"by feel." (it's probably true by now). Scalps Interest Rates, and and Index. No charts just a half dozen TT doms...he has levels and recognizes bluffing. Also pays member fees, like 10 cents; commissions stop after a certain point...
...I believe a great deal of the NAZDAQ volume, as much as 20-30% is the result of one firm in Kansas City...a former trader/programmer who programs algorhythms all day as a couple dozen minions monitor their progress.
The pit does have a feel - you can even be blindfold and go by volume and be able to judge the size of the trading "wave". Knowing who is on the other end of the order helps too so you can piggyback the known winners and heavy hitters. That's partly why pit traders usually make bad screen traders.
Yeah algo's is the way to go for those who know indicators work and understand how to speed them up. Also graybox assistance can help big time to improve a traders entries and exits, and if you know what to look for the scalp entry can run for hours.
Clever guy though to keep the human element imho if you are looking at longer term strategies.
