And went back to the corporate world? How did you do that with a massive gap in your resume? Most employers are conservative and don't like people with unconventional background.
I was a BD and member of the AMEX. It was not just trading, it was running a business in a regulated environment with escalating costs. To me, the MM business for equity options was no longer worth the risk reward. Too may option exchanges, too many orders crossed. Rather than build a new strategy to trade off floor without access to order flow, I chose to do something else. It was just not fun for me anymore. Time to move on.
I believe there is more value to trading off floor now as customer with a PM account, where you can trade whatever you want with good leverage, and no regulatory and infrastructure costs that BDs have.
