Macro-eco is always important for building good models, you can take economics as well.
And because your target is Trading, not pure research, economics becomes more important.
You don’t want to be sitting at the back running analysis while someone else is taking part in strategy development. Understanding how FED’s rate hikes and the CPI data might mess up with your strategies is key especially during these times.
Economics will be required to understand the ghost patterns as well and if you want a career ỉn Portfolio management.
Good luck
