In a Floating Strike Option with Lookback Feature (Partial Time), the strike price is floating. At expiration, the payoff on the call option is being able to purchase the underlying asset at the minimum observed price from inception to the end of the lookback time. Conversely, the put will allow the option holder to sell at the maximum observed asset price from inception to the end of the lookback time (Figure 63.1).
