You're chasing a pipe dream. To quote you from your other thread on the exact same subject: Put the $10k into the bank/money market. Study like hell and get into the best possible college you can, then study like hell some more & get the best possible GPA you can. Rinse and repeat with a graduate degree. With any luck, 10 years after graduation, you'll find $500k won't be such a pipe dream.
What kind of thread is this? Use a calculator or an excel sheet to calculate that. Anyway, some funny comment like this must be taken as a bearish indicator.
In your first year, you should be much more concerned with not losing your initial 20K rather than how much you can make.
It's definitely possible, but it's entirely a function of you and your trading system. The answer is "yes" if all of the following apply: a) You have a robust and comprehensive trading and risk management system that you have realistically tested and found to be net positive. b) The system is scalable up to the position size required to meet your income expectations. c) You have sufficient capital to trade your system as you tested it. d) You have confidence that your plan will work, and you have the experience and maturity as a trader to follow your plan exactly. That said, if all of the above were true you wouldn't be asking this forum whether it were possible -- you would know it is possible. So while it's definitely possible, it's almost certainly improbable.
20k to 500k translates into 2400% profit. Given r=e^(ln(Z)/n), where r is the required rate of return, Z is the aggregate return, n is the number of periods and e is the Euler's number, you would have: For 4 quarters => r=121,33% per Q or For 12 months => r=30,32% per month or For 252 days => r=1,269% per trading day. So, it is up to you to decide whether these figures are achievable or not.
Goto a casino. Put the entire balance on black (or red) 5 times in a row. You just have to win every round, 5 times in a row. There you got it: You made 640k outta 20k in 10 minutes. Ain't it sweet, almost risk free!!!!!!!!! (Using the above method you have a higher chance of succeeding than trying to reach your goal in the markets.)
