How much equity to make it full time?
$1000 + profits will not be enough to live off. Lets say living expenses are $1000 a month - you will need 100% a month to live.
You can make a good amount of profit says 50-100% profit through this business and if you are beginner then 100$ is good to start and you can make a good start and be more profitable through it .
You need a large quantity of funds says 200 - 500$ equity to do intra trade and can make daily profit and don't re-invest your profit again and again it can cause you in loss.
EVen 1 dollar, the equity does not is the thing to start trading you can do with 1 dollar even just thing is dont loose it and make more
For me I am still at the beginning of the road do not think deposit of a large capital ... I think that a small capital to start better .. Even out the level of good and sufficient experience .. Can raise capital after that
