This strategy is mostly only done by day traders. It requires that you have access to one to several real-time news sources and can make split second decisions. News and rumors can provide large amounts of volatility and high emotion creating great opportunities if traded properly. The biggest challenge of trading this strategy is anticipating the market’s reaction to the news and how it effects the price of the stock. Click here for more information on trading news and rumors.
If the strategy is within your risk limit, then testing begins. Manually go through historical charts to find your entries, noting whether your stop loss or target would have been hit. Paper trade in this way for at least 50 to 100 trades, noting whether the strategy was profitable and if it meets your expectations. If it does, proceed to trading the strategy in a demo account in real time. If it's profitable over the course of two months or more in a simulated environment, proceed with day trading the strategy with real capital. If the strategy isn't profitable, start over.
Scalping can appear easy because a scalper might make an entire day's profit within a few minutes. However, in reality, scalping can be quite challenging because there is very little room for error. If you do decide to try scalping, make sure that you do so by using a trading simulator, until you are consistently profitable and no longer make any beginning mistakes, such as not exiting your trades when they move against you.
Traditional investing – Traditional investing is a longer game and looks to put money in popular assets such as stocks, bonds, and real estate for long-term value appreciation. Realistic investment returns over a whole year are in the 5-7% range. Unless you are already rich and can invest millions, traditional investing returns too little to make much of a difference on a daily basis. However, the intelligent trader will also invest long-term.
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.
