# Bonus | Twin-Win

## Bonus Overview

Pay a premium to be long the underlying while protecting downside up to a barrier below the strike. 

In the case of bonus order, the protection consists of being protected at the reference price level at expiry up to the knockout barrier.

In the case of twin win order, the protection consists of not only being protected, but effectively flipping one’s exposure to short ETH up to the reference price; therefore one wins on both the upside post the breakeven price reference and makes money equivalent to having shorted ETH down to the knockout price.
