That isn’t arbitrage. Arbitrage entails making a guaranteed profit, not relying on predictable fluctuations.

Arbitrage over time is properly called arbitrage. If the fluctuations are known in advance, then you make a guaranteed profit by trading over time.

Yes, but you don't "know" the fluctuations in advance. You just have educated guesses about how they will mean-revert.
