Does Charming Traveling Merchant activate its ability?

Ruling: Yes, Traveling Merchant's ability triggers when moved by Charm or any other effect. The ability states "When I move" and will trigger regardless of how the movement occurs—whether voluntary or caused by an opponent's effect.

Sequence:

• Charm is played targeting Traveling Merchant
• Charm resolves, moving Traveling Merchant to a different battlefield
• Traveling Merchant's triggered ability "When I move, discard 1, then draw 1" goes on the chain
• The ability resolves: discard 1 card, then draw 1 card

Nuances:

• The ability triggers on ANY move, not just voluntary movement by the controller
• Recall is specifically defined as NOT a move, so the ability would not trigger on recall
• The trigger condition is simply "when I move" with no additional restrictions about who initiates the movement
