For example, I trade futures and currencies and had written off the data services expenses and the commissions. The agent informed me that I couldn't be a trader, since traders work for brokers or exchanges.

That's silly. It is commonly known that broker commissions are tax deductible; they are filed on the 1099B, usually provided by your broker. Software, consultant services etc. are all generally tax deductible as well. Don't take my word for it; five seconds on Google pulled this page up at Schwab that gets into the specifics.
Agent was bullshitting you, or trying to substitute a badge for competency.
