At the grain exchange they used to tell me that it took 6 months to a year for a trader who would make it to have a positive monthly return and it would take 1 to 2 years for a trader to be positive overall (making back the money you initially lost plus expenses 'invested'). This time line applies to traders who are in the market every day, the whole session, watching other real traders trade. (Note that is does not count the traders who leave, only the ones who eventually make it. So you have a huge survivorship bias here.)
I thought this was a little pessimistic. Not really. You can take up to several months learning how the market works, finding support and resistance, analyzing charts in multiple time frames and all in real time. (Analyzing charts in real time, prospectively is much more difficult than looking at completed charts in a book.) Then you have to devise a trading strategy to take advantage of your analysis which usually involves testing various types of trades over the course of several months, losing all the while. So lets say you've got it figured out. It doesn't do any good if you just cherry pick a few trades a day, you can't make a living at that. You have to learn how to consistently execute trades.
The real work is to be able to manage your losses and to take every trade that fits your criteria. Traders trade. Trades can take action without losing their discipline. The ability to do this is a whole other set of skills that you can only begin to work on only after you've gone throught the 4 to 6 months initiation. You are going to need 6 to 12 months of expenses, plus trading capital, plus a reserve to absorb your trading losses and still have trading capital AND a cushion left over.
Here is a good article on the trading mindset. (Note it has little to do with zenning out.)
MENTAL STATE by Vadym Graifer

"The truth is : if you want to be a trader, you must trade, you must change yourself from fearing to take a trade to cold-blooded readiness to react on valid signal. Working toward your goals and dreams, not sitting and doing nothing."
"A trader that cannot execute a trade is not likely to be successful at trading."
"Your success as a trader will be achieved when the probability of successful trades outweighs the probability of losing. This will not work if a trader only executes 1 of 10 trades. You desperately trying to pick the best trade rejecting trades that meet your criteria one by one. When you finally do take one and experience a loss on that cherry picking trade, it becomes more painful, reaching a point where it is impossible to take any trades at all. "

Also read the literature on what it takes to become an advanced chess player. Thousands of exposures to board positions over many months, presuming you had a sound basic understanding going in. Then you start to 'get it.' Thats the kind of training that learning to trade is going to take.
So my point is, a $5k account is not enough unless you already have a job and you are trading the european session. (I point out the european market as an alternative because you can't learn anything sneaking in a few trades during the day when you are supposed to be working. You need some way to a spend a couple of hours each day, full time on trading.)
