The United States has what's called the Pattern Day Trader (PDT) Rule. That means you need a min of $25k cash balance in your broker account in order to day trade more than 3x in a 5 day period. Since most traders take 3-5 trades per day, they are considered Pattern Day Traders. Many of our new students don't have $25k and that's OK.
There is a Hedge Fund we work with called Clique Fund, LP that allows students and traders to trade freely. They also have active risk managers working with their traders are making good trades and progressing. They provide all the software needed to trade, both long and short, and have low commissions.
