Welcome!

I meet a lot of new and wanna-be traders through my Meetup and here is the advice I lay out, with a little math

Let's say you have a lifestyle of $100K per year. The best traders on average have annualized returns of 10-20% a year. That's annualized. That means some years they may be up 50+%, other years down 40+%, but on average, over time, they make 10-20% a year. Let's be optimistic and say you can actually annualize 20% a year. That would mean you would need 5x capital, or $500K of trading capital to start with assuming you use good risk management.

This also assumes that when you have down years that you don't spend any of your trading capital, you just don't get a paycheck from your trading, so you'll need some other savings to pay for your drawdown periods. I'd guess that would mean you need another 1-2yrs of savings on hand. So now we're up to 600-700K. The reason this is important is that you must not spend your trading capital in drawdowns, because it will make it harder to recover from your drawdowns with a smaller and smaller account size.

With all of that said, this all assumes you actually have the skills and discipline to make 20% annualized. If it's only 10% then you need 2x that capital. While your attention-to-detail skills will be very helpful, it's only one tool you will need to master. Deciding to becoming a full-time trader is like deciding to become a doctor, a lawyer, or play professional sports. You can't just jump in and expect to be successful just because you are smart, work hard and are determined. It takes a lot of work and practice achieved over time. You will probably blow out 2-3+ trading accounts on your way because you have not yet mastered the skills needed, so you'll need some "tuition" money to lose on the way. It will probably take you at least a few years to get where you need to get to.

Enjoy the journey and try to minimize your tuition losses on the way.
