Auto-compound

Auto-compound means automatically collecting the trading fees a position has earned and reinvesting them back into the same position, so those fees start earning fees too. It turns a linear return into a compounding one without manual claiming.

Manually, compounding means periodically claiming fees and re-adding them — tedious and gas-sensitive. On an L2 like Robinhood Chain, cheap gas makes frequent compounding worthwhile, and Super9MM does it for you on a schedule or fee threshold.
