However, it might be best to not become too much of a market "expert". Some of the most famous and successful investors of all time, such as Peter Lynch, the famed manager of the huge Fidelity Magellan fund. He suggested that looking for clues in normal life is a great way to find opportunities. Lynch used to closely follow the shopping habits of his wife to see what brands people were buying. He believed that most people working professionally on the NYSE lived in a bubble.
A stop-loss order is designed to limit losses on a position in a security. For long positions, a stop loss can be placed below a recent low, or for short positions, above a recent high. It can also be based on volatility. For example, if a stock price is moving about $0.05 a minute, then you may place a stop loss $0.15 away from your entry to give the price some space to fluctuate before it moves in your anticipated direction.
ECN/Level 2 quotes: ECNs, or electronic communication networks, are computer-based systems that display the best available bid and ask quotes from multiple market participants and then automatically match and execute orders. Level 2 is a subscription-based service that provides real-time access to the Nasdaq order book composed of price quotes from market makers registering every Nasdaq-listed and OTC Bulletin Board security. Together, they can give you a sense of orders being executed in real time.
Sector leader -- Most of the best starter stocks are either the leader in their respective businesses or very close to it. (You will note this later on in this article when we give some good beginner-friendly stock examples. There's a time and place to invest in up-and-coming companies, but it's smart to save those for after you've learned the ropes.)
Now, imagine that you decide to buy the stocks of those five companies with your $1,000. To do this, you will incur $50 in trading costs—assuming the fee is $10—which is equivalent to 5% of your $1,000. If you were to fully invest the $1,000, your account would be reduced to $950 after trading costs. This represents a 5% loss before your investments even have a chance to earn.
By understanding your risk tolerance, you can avoid those investments which are likely to make you anxious. Generally speaking, you should never own an asset which keeps you from sleeping in the night. Anxiety stimulates fear which triggers emotional responses (rather than logical responses) to the stressor. During periods of financial uncertainty, the investor who can retain a cool head and follows an analytical decision process invariably comes out ahead.

Beware of confirmation bias: With penny stocks, beware of confirmation bias: the tendency to interpret information in a way that that conforms to your preexisting beliefs. This is something that afflicts nearly every human being and most new investors (or rookie poker players). Seeing what you want to see (albeit usually subconsciously) can be incredibly costly.
