A scalp trader can look to make money in a variety of ways. One method is to have a set profit target amount per trade. This profit target should be relative to the price of the security and can range between .%1 - .25%. Another method is to track stocks breaking out to new intra-day highs or lows and utilizing Level II to capture as much profit as possible. This method requires an enormous amount of concentration and flawless order execution. Lastly, some scalp traders will follow the news and trade upcoming or current events that can cause increased volatility in a stock.
Whether you are scalping EUR: USD, other currency pairs, or other assets outside of forex, it’s important to pay attention to the details. Scalping typically occurs in 5-20 minute increments. However, if you were trying to implement a one-minute scalping strategy, volume indicators, M5/M15 time charts, and price action trends should be the first things you look at.
The systems by which stocks are traded have also evolved, the second half of the twentieth century having seen the advent of electronic communication networks (ECNs). These are essentially large proprietary computer networks on which brokers can list a certain amount of securities to sell at a certain price (the asking price or "ask") or offer to buy a certain amount of securities at a certain price (the "bid").
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.
