Lookback Option
A lookback option is a type of exotic derivative that allows the holder to look back over the life of the option to determine the optimal payoff. These options typically grant the right to buy the asset at its lowest price or sell it at its highest price reached during the holding period.
Because they provide the holder with the most favorable price, they are significantly more expensive than standard options. Lookback options are ideal for traders who are uncertain about market timing and want to ensure they capture the best possible price movement.
In the digital asset space, they are highly valued for their ability to hedge against volatility by effectively providing a perfect market entry or exit. They are essentially the most expensive type of option due to the extreme benefit they offer to the holder.
