The underlying may therefore only hover in a certain range (just moving inside a tunnel with this instrument, the investor can almost bet on the volatility of the underlying). Fluctuating shares break through one of the boundaries rather than the values.
Parisian options cams only when the barrier condition is satisfied for a specified period of time, so if, for example in a down-and-in option, the price for a month is less than the Barrier Levels. Depending on whether the length of time must be at or below cumulative piece, one distinguishes between the pure Parisian options and the cumulative Parisian options, also called Parasian options and VPS Forex Brokers.
Binomial options pricing model (BOPM) is a discrete model for the modeling of securities and stock price developments. Here, several development possibilities are postulated and each assigned with a positive probability for each time step. The restriction to only two possibilities for development is also called the binomial model.
The binomial model is a method for the determination of fair option prices. Here, the duplication principle is applied, which assesses the value of the option when the stock price rising and the falling price of the option in the share price in its simplest form. The call value is independent of the probability of price increase or decrease, and regardless of the risk attitude of market participants.

The quantity shares in the portfolio assumes the same value in both ways is – regardless of their probability – risk free. Call 1 short here means that a call option is sold ( it is the short position of call related).
The delta factor is important in the evaluation and hedging. It is the sensitivity of the option price to changes in the share price by one unit. The delta of a call option is positive, the delta of a put option is negative. In the two-stage Binomial Delta time is given for the two steps, wherein in the second step, the time is taken into account the up and down movement.
