If you have 10k and you buy stocks worth 480k, so you got 470k as loan from the broker.....then let's say you sold the stocks for a value of 500k. You return 470k to the broker and keep your 10k and the 20k profit. You will end up paying the brokerage and taxes.
then it will be 48000
and i earned 2000 then what will be my margine charge?
and what will be my total profit?
