The Momentum and Reversal trading strategies are the #1 and #2 best trading strategies out there. These two day trading strategies are being used by thousands of our students who have participated in the Warrior Trading Day Trading Courses. In fact, in a survey of 100 of these students, over 80% are now trading profitably thanks to these strategies (click here for survey details) These strategies can be the basis for your $200/day trading plan.
Different markets require different amounts of capital to day trade. Stocks are popular, but also the most capital intensive. If you want to day trade stocks in the US, the absolute minimum you need is $25,000. And you'll actually need more because you need to keep your balance above $25,000. Starting with $30,000 or more is recommended. The stock market provides up to 4:1 leverage on day trades.

The first 9 successful trades produce $900 in profit. On the 10th trade, when the position is down $50, instead of except the loss the untrained trader purchases more shares at a lower price to reduce his cost basis. Once he is down $100, he continues to hold and is unsure of whether to hold or sell. The trader finally takes the loss when he is down $1,000.
But there is an added risk with the shorter time frame. A wide spread between the bid, the ask and commissions can eat too large a portion of your profits. Swing traders can struggle with this too, but the effect is amplified for the day trader. Day traders can find themselves doing all the work, and the market makers and brokers reap the benefits.
You're probably looking for deals and low prices, but stay away from penny stocks. These stocks are often illiquid, and chances of hitting a jackpot are often bleak. Many stocks trading under $5 a share become de-listed from major stock exchanges and are only tradable over-the-counter (OTC). Unless you see a real opportunity and have done your research, stay clear of these.
