Hey, NSE Certified market professional is nothing but a certification based on the number of NCFM exams you have cleared... If you clear the first 3 modules of NCFM then you'll get a Nse certified market professional level-1 certification and so on..
what modules to take up depends on your area of interest and your specialisation...I would suugest you to complete the 1.Financial markets Beginners module, 2. Capital Markets(Dealers module), 3. Derivatives Market(Dealers Module) first to get a basic understanding of the markets and its functions
After this you can go for Portfolio management module, Debt market module, mutual funds module, currency derivatives module..etc
You can download the study materials and also view the contents of each module in the NSE India website...so go through it decide which all modules would be useful for you.... NCFM Certifications will give you a very good knowledge about the Investments and stock market...All The Best
