If you mention CMT, even to someone in the industry, generally you will see a puzzled look on their face. The biggest reason for this is because of the lack of awareness of what Technical Analysis is. Most feel that it is a form of voodoo, however if you boil down technical Analysis to its basic form it is simply looking at statistical data over a given period of time in an effort to improve your probability of successful trades based on tested trading methods. Technical Analysts simply look at the data on charts vs balance sheets and cash flow statements.
With that said, I have to say that I am in the industry and also an affiliate of the Market Technicians Association, who administers the CMT program. Currently I am preparing to take level two in the fall. Personally I am doing this for professional advancement throughout my financial services career, however this is not the only certification that I will pin that on. Many industry professionals actually carry two certifications, as an example John Bollinger(creator of Bollinger Bands, and president of his own capital management firm) carries both the CFA and the CMT.
Ultimately you would have to decide where you want to go through your career, and determine what certifications, if any, would show your potential employer(s) your competencies in the area for which you are applying.
As far as the program is concerned, you should expect to pay annual fees(about 400.00) to be an affiliate of the MTA during your testing period, which they give you up to five years to complete. There are benefits associated with this fee, such as a website with links to help you in your studying, discounts on various industry magazines and trading/TA software. As far as the passing rate. My level one exam, about 70% passed, and colleagues of mine that took level II said about 50% passed.
