Retail day traders are competing with professionals. Pros know the tricks and traps. They have expensive trading technology, data subscriptions and personal connections. They’re perfectly outfitted to succeed, and even then they often fail. Among these pros are high-frequency traders, who are looking to skim pennies or fractions of pennies — the day trader’s profit — off every trade. It’s a crowded field, and the pros love to have inexperienced investors join the fray. That helps them profit.
Price volatility and average day range are critical to a day trader. A security must have sufficient price movement for a day trader to achieve a profit. Volume and liquidity are also crucial because entering and exiting trades quickly is vital to capturing small profits per trade. Securities with a small daily range or light daily volume would not be of interest to a day trader.
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.
