Essentially it's borrowing money to buy stock/(or whatever) making gains, then paying back what you borrowed plus interest. You get to keep the rest

You can make a shit load of money because you are making a profit from money you don't even have, but if you make a loss it fucks you hard

I understand the borrowing money to buy aspect

what I dont understand is the difference between a short and a long aspect

and yes I have been reading wikiedia and google but I am too brainlet to understand. Could you give a practical example of a short trade and a long trade

You borrow it first, then sell it. Then buy it back and give it back.
