i. Trading Psychology: The psychological aspect of trading is extremely important, and the reason for that is fairly simple: A trader is often darting in and out of stocks on short notice, and is forced to make quick decisions. To accomplish this, they need a certain presence of mind. They also, by extension, need discipline, so that they stick with previously established trading plans and know when to book profits and losses. Emotions simply can't get in the way.
ii. Understanding Fear: When a trader's screen is pulsating red (a sign that stocks are down) and bad news comes about a certain stock or the general market, it's not uncommon for the trader to get scared. When this happens, they may overreact and feel compelled to liquidate their holdings and go to cash or to refrain from taking any risks. Now, if they do that they may avoid certain losses - but they also will miss out on the gains.
Traders need to understand what fear is simply a natural reaction to what they perceive as a threat (in this case perhaps to their profit or money-making potential). Quantifying the fear might help. Or that they may be able to better deal with fear by pondering what they are afraid of, and why they are afraid of it.
Also, by pondering this issue ahead of time and knowing how they may instinctively react to or perceive certain things, a trader can hope to isolate and identify those feelings during a trading session, and then try to focus on moving past the emotion. Of course this may not be easy, and may take practice, but it's necessary to the health of an investor's portfolio.
iii. Greed Is Your Worst Enemy: There's an old saying on Wall Street that "pigs get slaughtered." This greed in investors causes them to hang on to winning positions too long, trying to get every last tick. This trait can be devastating to returns because the trader is always running the risk of getting whipsawed or blown out of a position.
iv. Greed is not easy to overcome: That's because within many of us there seems to be an instinct to always try to do better, to try to get just a little more. A trader should recognize this instinct if it is present, and develop trade plans based upon rational business decisions, not on what amounts to an emotional whim or potentially harmful instinct.
v. The Importance of Trading Rules: To get their heads in the right place before they feel the emotional or psychological crunch, investors can look at creating trading rules ahead of time. Traders can establish limits where they lay out guidelines based on their risk-reward relationship for when they will exit a trade - regardless of emotions. For example, if a stock is trading at $10/share, the trader might choose to get out at $10.25, or at $9.75 to put a stop loss or stop limit in and bail.
Of course, establishing price targets might not be the only rule. For example, the trader might say if certain news, such as specific positive or negative earnings or macroeconomic news, comes out, then he or she will buy (or sell) a security. Also, if it becomes apparent that a large buyer or seller enters the market, the trader might want to get out.
Traders might also consider setting limits on the amount they win or lose in a day. In other words, if they reap an $X profit, they're done for the day, or if they lose $Y they fold up their tent and go home. This works for investors because sometimes it is better to just "go on take the money and run," like the old Steve Miller song suggests even when those two birds in the tree look better than the one in your hand.
vi. Creating a Trading Plan: Traders should try to learn about their area of interest as much as possible. For example, if the trader deals heavily and is interested in telecommunications stocks, it makes sense for him or her to become knowledgeable about that business. Similarly, if he or she trades heavily in energy stocks, it's fairly logical to want to become well versed in that arena.
To do this, start by formulating a plan to educate yourself. If possible, go to trading seminars and attend sell-side conferences. Also, it makes sense to plan out and devote as much time as possible to the research process. That means studying charts, speaking with management (if applicable), reading trade journals or doing other background work (such as macroeconomic analysis or industry analysis) so that when the trading session starts the trader is up to speed. A wealth of knowledge could help the trader overcome fear issues in itself, so it's a handy tool.
In addition, it's important that the trader consider experimenting with new things from time to time. For example, consider using options to mitigate risk, or set stop losses at a different place. One of the best ways a trader can learn is by experimenting - within reason. This experience may also help reduce emotional influences.
Finally, traders should periodically review and assess their performance. This means not only should they review their returns and their individual positions, but also how they prepared for a trading session, how up-to-date they are on the markets and how they're progressing in terms of ongoing education, among other things. This periodic assessment can help the trader correct mistakes, which may help enhance their overall returns. It may also help them to maintain the right mindset and help them to be psychologically prepared to do business.
Bottom Line, it's often important for a trader to be able to read a chart and have the right technology so that their trades get executed, but there is often a psychological component to trading that shouldn't be overlooked. Setting trading rules, building a trading plan, doing research and getting experience are all simple steps that can help a trader overcome these little mind matters.
