The Gap & Go! is one of those Intraday Trading Strategies that capitalises on the gappers. Gappers are the securities that show a gap between the prices on a chart-when there is an upward or downward movement in the price with no trading in between. Gaps can be created by various factors like earnings announcements, any other type of news releases or a change in the outlook of the analysts.
The common use of buying on margin (using borrowed funds) amplifies gains and losses, such that substantial losses or gains can occur in a very short period of time. In addition, brokers usually allow bigger margin for day traders. In the United States for example, while the initial margin required to hold a stock position overnight are 50% of the stock's value due to Regulation T, many brokers allow pattern day trader accounts to use levels as low as 25% for intraday purchases. This means a day trader with the legal minimum $25,000 in his account can buy $100,000 (4x leverage) worth of stock during the day, as long as half of those positions are exited before the market close. Because of the high risk of margin use, and of other day trading practices, a day trader will often have to exit a losing position very quickly, in order to prevent a greater, unacceptable loss, or even a disastrous loss, much larger than her original investment, or even larger than her total assets.

Head over to websites like Reddit and you’ll see many trading dummies who will often fall at the strategy hurdle, taking the first momentum examples they see and losing money left, right and center. Savvy traders will employ day trading strategies in forex, grain futures and anything else they’re trading in, to give them an edge over the market. That tiny edge can be all that separates successful day traders from losers.
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.
