Quote from Option Trader:
With the algorithms, just a few is all that's needed nowadays.
This is from a resume at the following link "http://www.datashaping.com/resumes16200r.shtml"
--* An in-depth knowledge of Mantas product Architecture to thoroughly understand the interaction between the data mart and other system components.
* Sound understanding of Mantas scenarios and business problems addressed at various stages of TSD writing, scenario development, scenario tuning, scenario customization and involvement of multiple threshold sets, jobs and templates configuration for clients at the client site with the responsibilities of data analyst/data miner as per requirement.
*Detailed knowledge of behavior detection as it applies to the financial services domain in the following areas: trading and market making, money laundering within banking and brokerage firms, and retail brokerage customer surveillance.--
Most brokers have trading desks and/or do market making, and clearing firms. At one of these stages they know who you are, your positions, and what percentage you have at risk on a position. It's your broker that trades against you.
Only guy to date that's said so in public is Bill Cara
{(Humungous Bank & Broker's) H B & B trades against the order flow of its clients, including the hedge funds. It's basically a no-risk business because the broker-dealers hold the collateral, analyze the holdings and the strategies, and use this all-important info for their own gains. And, in the futures business, for every gain there is a loss.
Would any casino player play 21 (blackjack) if the dealer's knowledge of all the cards on the table was a rule of the house? Would anybody play poker if one of the players knew in advance everybody's cards and how they would play them (and was the banker)?
I have been saying this for years but too few people listen. ... ... HB&B is the player that is keeping government regulation out of "their" capital market, and that's because they are the winner and everybody else the loser. But, except for the fact it is the People's capital market, they get away with it because the People have stopped thinking -- they've been brainwashed into believing that "our" market needs to be under the control of HB&B.}
