How do I get a loan to invest in stocks?
Do you want to invest or trade?
From what I know is that loans cannot be used for speculation activities. I am not sure though , be sure to read that document you sign for personal loan or credit card well. Usually the bank employee will under the table approve the loan and themselves say “don’t tell anyone you are trading in stock market with this loan”.
Well if you are doing well , get returns and able to service the debt then great but if you lose everything, you are in debt and if they find out you played in stock market, I have no idea how well that’s going to go.
The thing is you are looking for leverage and speculation. I believe F&O were created in market for this very specific purpose. Better to stick with that!
I am not too sure if the OP knows everything you are saying. I don’t even know if he wants to invest or trade, so I asked him that 
Trading purpose
