Barter Wise is kind of redundant with your background, which I think of as a mix of Indiana Jones and a prospector.
Alternative can be
Perceptive: You gain Advantage when Testing to gain information about your surroundings or find things that may be hidden. You gain this even while asleep.
Survivalist: You gainAdvantage when Testing to forage for food, find water, seek shelter, or create shelter in the wild.
Trapmaster: You gain Advantage when Testing to create, locate, and disarm traps. You also gain Advantage on Save Tests against traps.
Eidetic Memory: When Testing to recall information, you have seen or heard previously—even in passing—you succeed on a roll of 4, 5, or 6.
Charismatic: You gain Advantage when attempting to convince someone of something or otherwise influence them.
Explain how you view you background vs Barter wise or pick a different trait
If you let me know the reason you became an adventurer I can get you started. If it is just a continuation of your profession then expect something drastic to drag you further from you homeland than you have typically traveled before.
Look out for Baby :)
