Limit order -- A limit order differs from a market order in that the trade is only completed at a certain price. For example, if you enter an order to buy 10 shares of Nike at $70 each, the order will only go through if the broker can fill at it at a price of $70 per share. Limit orders are a good way to buy and sell stocks that trade less frequently, since there may not be enough willing sellers to fill a market order at a reasonable price. These orders are a good for “set and forget” investing, since you can place a limit order that will remain in effect until a stock reaches the price at which you’d like to buy.

One way to “beat” the market is to invest on a regular basis. Instead of trying to time when the market is high or low, regular investing — known as dollar-cost averaging — will guarantee you’ll buy more shares when the market is low and fewer when it’s high. Over the long haul, this type of investing can make temporary market declines a good thing.
It’s a tumultuous time for online stock brokers.

Basically, the goal of investing is to commit money, and in return that money will grow. However, investing involves risk. Whenever you’re not holding your money in your own bank account, there’s a risk of loss. With some investments, the risk is low; with others it’s high. The higher the risk, the more you’d better potentially earn to take that risk.
Technically, you are only limited by the minimum amount required by a brokerage firm or mutual fund company to open an account.

I oftentimes see my friends blow money mindlessly and then when it comes time for them to do something to benefit themselves, they claim to not have money. I know people that will go out and spend hundreds of dollars at restaurants, at bars, on sporting tickets, video games, and other unnecessary items but claim that they are not able to save money each paycheck.
Remember to factor time into your goals. This is especially true for long-term projects such as retirement funds. For example: John begins saving at age 20 using an IRA (Individual Retirement Account) earning an 8% return. He saves $3,000 a year for the next ten years, then stops adding to the account but keeps the IRA invested in the market. By the time John is 65, he will have $642,000 built up. 
To the inexperienced investor, investing may seem simple enough - all you need to do is go to a brokerage firm and open up an account, right? What you may not know, however, is that all financial institutions have minimum deposit requirements. In other words, they won't accept your account application unless you deposit a certain amount of money. With a sum as small as $1,000, some firms won't allow you to open an account.
