Positive Slippage

Positive Slippage occurs when your trade gets you more tokens than you were expecting. This can happen when the price of the asset you are buying goes down and you end up getting more tokens than you originally thought.

Many aggregators take this positive slippage. When that happens, Matcha Meta does not currently benefit.
