strick price?
The description did not mentioned about Strike Price. It confused me.

down & out call
so there are up & out call, up & in call, and they combined into a vanilla call (suppose the same strike price). Similarly, there are down & out put, down & in put. But it is more difficult to image a down & out call. Here, on page 11, there are two diagram, one for the ordinary call, another one for the down & out call. http://www-maths.mcs.st-andrews.ac.uk/~rac/MT4551/FM12.pdf It doesn't take the premium into account, the explantion is still not clear enough.

Creation of Barrier options
The "citation needed" was recently removed for the sentence "Barrier options were created to provide the insurance value of an option without charging as much premium. " Perhaps this is common knowledge, but it would still be good to know when barrier options were first created. Ulner (talk) 19:21, 19 September 2009 (UTC)
