I will whip something together later. Hopefully, my dealer is stopping by and I will be mellow while doing it. General idea is that you can see people post orders as actual quotes and quantities traded broken by actual fills. As a result you can guess who got shafted, who cleaned up and maybe come up with causal relationships. In spooz it's hard to make heads and tails of TaQs unless you really zoom into a very small window. Of course smaller players like myself would not have the infra to trade the book in ES anyway, that's Jump and HRT territory. However, in something less liquid and speedy you can see stuff like "oh, look some guy posted 500 at the offer and instantly the bid faded, he chased and got f*cked (also instantly)". You see these patterns enough times and can actually use them as either source of alpha or an adversity model.
Congratulations, you just shit on one of the half dozen people on this forum who are professionals who actually trade for a living and know wtf they're talking about. I have to agree with the douche assessment. Double douche actually because people like you make the people who do add value less likely to stick around and contribute. What's your problem anyway?
I think it is safe to say SP will not be gaining 900 points by March 31st. If anything, it is looking to lose a few hundred more, and prolly be at around 1700-1800 by end of April. That's a nice comfortable 50 percent drop, yes?
