A stop-loss order is designed to limit losses on a position in a security. For long positions, a stop loss can be placed below a recent low, or for short positions, above a recent high. It can also be based on volatility. For example, if a stock price is moving about $0.05 a minute, then you may place a stop loss $0.15 away from your entry to give the price some space to fluctuate before it moves in your anticipated direction.
Many orders placed by investors and traders begin to execute as soon as the markets open in the morning, which contributes to price volatility. A seasoned player may be able to recognize patterns and pick appropriately to make profits. But for newbies, it may be better just to read the market without making any moves for the first 15 to 20 minutes. The middle hours are usually less volatile, and then movement begins to pick up again toward the closing bell. Though the rush hours offer opportunities, it’s safer for beginners to avoid them at first.
Finally, keep in mind that if trading on margin—which means you're borrowing your investment funds from a brokerage firm (and bear in mind that margin requirements for day trading are high)—you're far more vulnerable to sharp price movements. Margin helps to amplify the trading results not just of profits, but of losses as well if a trade goes against you. Therefore, using stop losses is crucial when day trading on margin.
Individuals who attempt to day trade without an understanding of market fundamentals often lose money. Technical analysis and chart reading is a good skill for a day trader to have, but without a more in-depth understanding of the market you're in and the assets that exist in that market, charts may be deceiving. Do your due diligence and understand the particular ins and outs of the products you trade.
The intraday trading strategy to be used also depends upon the traders’ personal trading styles, along with being dependent on the market conditions. Some traders are very active and do many trades a day, with large position sizes, catching even the small price movements; while there are others who trade only on specific news events or only on tendencies that they have well researched.
Traders pay close attention to intraday price movements by using real-time charts in an attempt to benefit from short-term price fluctuations. Short-term traders typically use one-, five-, 15-, 30- and 60-minute intraday charts when trading within the market day. Typically, intraday scalping uses one- and five-minute charts for high-speed trading. Other intraday trading strategies may use 30- and 60-minute charts for trades that have hold times of several hours. Scalping is a strategy of transacting many trades per day that hopes to profit from small movements in a stock's price. The intraday trader may hold their positions for a longer period but still operate under high risks.
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.

Unless you see a real opportunity and have done your research, stay clear of these.
