Must be a real aquatic whale or dolphin. The whale must make a human-understandable decision upon seeing, hearing, or sensing the market as input.
The whale must provably understand and acknowledge the market, so no random waiting and guessing. Any form of working human-whale translation is permitted for input and output.
The bet must be automatically placed after correctly processing the whale output, without human intervention.

For posterity
Let's just say, I see a whale, I shout at it a description of a market, and I wait for some sign (say, whether they turn left or right), then, I make a bet about that. Would that resolve this YES?
Or does the whale need to actually understand what I told them?
The whale must understand the input and produce an output specifically in response to the input.
