Aside anything trading needs a lot of know how as well as a stable income to back up with and that's to say you can't trade without a source of income. And again I pointed out something you said about taking a loan, absolutely a bad idea and a destructive force i tell you.taking a loan to trade or take up some risky decisions put one in a state of regrets so instead i concur to what he's told you and as you grow in trading take note that you'll always generate loses and gains.
If we compare both investing and trading together we say trading is more risky than investing. But even the investing you are not even advice to go for loan to invest, talk more of trading which is generally agreed to be risky, this is because with your capital been from loan it puts you in difficult situations like wanting to make up the money fast to pay up or been too afraid to lose the money and this two affects your psychology while trading which usually results into losing. So it is a bad step using loan to trade or even invest.
Extra income aside trading gives you extra confidence in the market and sharpens your psychology too which I can say contribute to the success of your trades because with extra income elsewhere you don’t enter trades with the mindset of your next meal depending on such trades and this even gives extra patience not to enter some trades which might look risky and could save you from loses most of the time
