《外汇交易实战图表与交易心理 》 作 者:(新加坡)许强 (美国)Gary Weiss



As to whether any of these option varieties represents value, is a very difficult idea to assess However, one of the main points in presenting these ideas in the first place is to get the point across that there are multiple variations for approaching the foreign exchange option market,that often times can create multiple levels of possible outcomes.

In these four examples, the static assumptions that have been used and also their relative simplicity, can itself be misleading. For example, even when evaluating the possible performance characteristics of a change in the underlying spot price throughout any of the above examples,it is easy to understand that the numbers of possible outcomes are almost unlim ited. Further, by changing any of the single assumptions such as price, strike, or even time value, the complexion of that option can take on an almost entirely different set of characteristics. The question, therefore, as to whether anything to do with “digital” options is worth the further complexity as opposed to generic foreign exchange options, is a critical issue.

As with the topic of trading generic options, the idea of “digital” options is really a view towards the portfolio effect of an overall trading strategy. Since the market often moves in unpredictable way and times, the idea of creating value at different levels of price and time is a sensible one. And, over time,this sort of approach should only enhance the return of any trading system. The idea therefore, in terms of these more esoteric vehicles is to further refine the topic. Digital options represent one of the most flexible ways to put together a u niquely structured portfolio of currency positions. Until very recently, this market was somewhat restricted by certain factors. Including the fact that there were just very few groups that were willing to make prices for these types of options. This however, has changed. Even in smaller size units, these types of options and their multiple variations are now reasonably attainable by most traders. Further, the ability to customize much of their underlying criteria, is an idea that seems to be expanding all the time.
