style: minor refinement of trade text

also remove unnecessary conditional

this is a huge improvement but we might consider also making it so only
non-zero influences are shown, we'll need to re-style the UI though,
simply filtering out the zero influences doesn't look great (and 1 sided
trades look weird, e.g., 1 side has 0 influences, and the other has
some)
