For most students, once his or her accuracy has improved the next step is increasing positions sizes to maximize profits. If you’ve been trading at 65% success with 1:1 or 2:1 profit loss ratios for at least a couple of months you should be starting to feel pretty confident. Now it’s time to increase your position sizes. Since you’ve been working with a $100 max loss, you’ve probably rarely exceeded 2000 shares.
Following the 1987 stock market crash, the SEC adopted "Order Handling Rules" which required market makers to publish their best bid and ask on the NASDAQ. Another reform made was the "Small-order execution system", or "SOES", which required market makers to buy or sell, immediately, small orders (up to 1000 shares) at the market maker's listed bid or ask. The design of the system gave rise to arbitrage by a small group of traders known as the "SOES bandits", who made sizable profits buying and selling small orders to market makers by anticipating price moves before they were reflected in the published inside bid/ask prices. The SOES system ultimately led to trading facilitated by software instead of market makers via ECNs.
First, find the lowest point of the pullback to determine the “stop out” point. If the stock declines lower than this point, you should exit the trade in order to limit losses. Then find highest point of the recent uptrend. This becomes the profit target. If the stock hits your target price or higher, you should consider exiting at least a portion of your position, to lock in some gains.
Smaller moves, easier to obtain - A change in price results from imbalance of buying and selling powers. Most of the time within a day, prices stay stable, moving within a small range. This means neither buying nor selling power control the situation. There are only a few times which price moves towards one direction, i.e. either buying or selling power controls the situation. It requires bigger imbalances for bigger price changes. It is what scalpers look for - capturing smaller moves which happen most of the time, as opposed to larger ones.
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.
