Interesting. I knew a guy that was on the trading floor in 1987.
"I only knew one person when it was Knight-Trimark, they were well funded and I think he was in the Westchester County, New York office. And I know he shorted into my order flow. And once I squeezed him on a stock and pissed off. But then again, I knew my orderflow, he did not. I knew how to trade the orders and trade around him. His name was Andrew."
Crazy shit back then.
Most of my back ground is science and engineering, biochemical and patents.
I came real close to taking a start up of mine public 20 years ago.
I am so glad I did not. Just not worth the headache.
