A sample answer to question 1

What does a typical day as a sales trader involve, and what qualities make a good one?

My day starts before the open, reading overnight news, checking what companies are reporting and reviewing client positions and axes. I speak to clients, mostly portfolio managers and traders at asset managers and hedge funds, about market colour, flow, and ideas from research, and I take their orders. During the session I execute, deciding whether to work an order through algorithms, in the lit or dark venues, or commit capital on a block, depending on the desk's model. I keep clients informed on progress and slippage, liaise with research, the trading desk, compliance and operations, and handle any errors. After the close, I review the day's executions and prepare for tomorrow. The best sales traders combine market knowledge with clear communication, integrity, calmness under pressure and the ability to build trust, because clients give business to people they believe will protect their interests.

Common mistake to avoid: Seeing it as simply taking orders; ignoring compliance responsibilities
