Help needed as to where to show this as expense

Dear All

I am a salaried person and I do trading and some investing in equity markets. 

I file ITR-4 every year as I do Equity, Futures and Options, which are mostly on the losing side.  Analysing that my skills are stupid enough, I decided to take up an Equity subscriptttion service for a year, which costed me Rs. 30000.  Now, can I show this as expense in ITR-4 and if yes please tell the section and point number in ITR-4, where I could show this as expense

Thanks a lot
