Barrier Option?

[Garima Sharma]

There are two main variations of barrier options, ‘in’ and ‘out’ options. ‘In’ options are initially inactive, that is to say that the investor initially has no rights on the underlying share, so the option is, in effect, worthless. When the underlying share reaches the price specified in the barrier option formula, then the option activates. If the underlying share never reaches the specified price during the life of the option, then it expires with no value.I used this option while trading under www.alpari.com
