Russian Option(redirected from Russian Options)
An option giving the holder the right but not the obligation to buy (for a call) or to sell (for a put) the underlying asset at the best price that occurs between the start of the option and the time it is exercised. What distinguishes a Russian option is the fact that there is no expiration date. The holder can wait indefinitely for an advantageous price and exercise the option. It is a type of lookback option.
