Intraday means "within the day." In the financial world, the term is shorthand used to describe securities that trade on the markets during regular business hours. These securities include stocks and exchange-traded funds (ETFs). Intraday also signifies the highs and lows that the asset crossed throughout the day. Intraday price movements are particularly significant to short-term or day traders looking to make multiple trades over the course of a single trading session. These busy traders will settle all their positions when the market closes.
When there are higher low points along with stable high points, this suggests to traders that it is undergoing a period of consolidation. Consolidation usually takes place before a major price swing (which in this case, would be negative). Learning about triangle trading and other geometric trading strategies will make you a much better swing trader.
To offset this, day traders are often offered the "opportunity" to leverage their portfolios with more margin, four times the buying power rather than double. Taking larger leveraged positions can increase percentage gains to offset costs. The problem is that no one is right all the time. A lack of focus, discipline, or just plain bad luck can lead to a trade that goes against you in a big way. A bad trade, or string of bad trades, can blow up your account, where the loss to the portfolio is so great the chances of recovery are slim. For a swing trader, a string of losses or a big loss can still have a dramatic effect, but the lower leverage reduces the likelihood that the results wipe out your portfolio.
In March 2000, this bubble burst, and a large number of less-experienced day traders began to lose money as fast, or faster, than they had made during the buying frenzy. The NASDAQ crashed from 5000 back to 1200; many of the less-experienced traders went broke, although obviously it was possible to have made a fortune during that time by short selling or playing on volatility.[9][10]

Scalping can appear easy because a scalper might make an entire day's profit within a few minutes. However, in reality, ​scalping can be quite challenging because there is very little room for error. If you do decide to try scalping, make sure that you do so by using a trading simulator, until you are consistently profitable and no longer make any beginning mistakes, such as not exiting your trades when they move against you.
If the market is trending down, they would short securities that exhibit weakness when their prices bounce. Most independent day traders have short days, working two to five hours per day. Often they will practice making simulated trades for several months before beginning to make live trades. They track their successes and failures versus the market, aiming to learn by experience.
In addition to knowledge of basic trading procedures, day traders need to keep up on the latest stock market news and events that affect stocks—the Fed's interest rate plans, the economic outlook, etc. So do your homework. Make a wish list of stocks you'd like to trade and keep yourself informed about the selected companies and general markets. Scan business news and visit reliable financial websites.
