Hey! What a co-incidence. I subscribed to the free 3-day trial this week for the S&P500 pit, after hearing some hedged recommendations.
Long story short ... after 1.5 days I turned it off. Drove me nuts. It was the service with the commentary, with the actual noise in the background. Even if it drove me nuts I would have persisted if I thought it would add value, but I couldn't see it doing so. There are times when I think it might be useful, but there are some serious questions that I was asking myself which I couldn't answer to my own satisfaction.
Now the long story.
The pit (S&P500) trades about 20% of the value of the screen-based product (the emini ... sorry TH ... the $50/per point FUTURE CONTRACT
). There's a problem right there for me ... why would I listen to the contract that is the little brother (or sister ... nothing if not PC) for direction on the much larger volume contract? I had heard that sometimes the pit leads the screen, a big local can search out stops in the abscence of 'paper' interest for example and move the market, a move a scalper for instance could take advantage of. Numerous times I did hear a 'top-tenner' (big local) was attempting to shift the price (look, to be fair after 1.5 days I don't think I can draw a fair conclusion, but each time the top-tenner did this he was so wrong....maybe it was a spoof while his office scooped up the screen-based contract...a possibility and if someone as dumb as me can think of this I imagine these guys can, and do).
There was an appreciable increase in pit-noise as we went through significant levels. But ... I can see the significant levels in front of me... the noise just confirmed it. I dunno, maybe this is a useful thing?
There was a substantial rally (I think it was Wednesday, might have been Tuesday), the start of which co-incided with Morgan Stanley buying big on the floor. But there were many times that big names like this came in, transacted in size, and had zero impact on the ensuing price behaviour ...
After so long screen-based trading (I have never traded in a pit/on a floor) maybe I am just used to screen-based trading - the moves all flow through the chart or whatever I am looking at (TH looks at the DOM and sees moves flowing through there). The noise was a distraction.
To be fair to the vendors, I only took a 3-day trial, so maybe a longer period of experimentation would have changed my perceptions. The trial was free, so by all means when you are ready give it a go. Even if you want to try it for a month its not going to break the bank. I wouldn't worry about follow-up pestering sales calls - these guys were so disorganised it took me over a week just to arrange a free trial. I ended up going straight to tech support and they connected me, the admin/sales people were just hopeless. Since the trial ended, no follow up at all.
