Because scalpers focus on short-term positions with low-profit margins, the best scalping strategies (such as the Triple S strategy mentioned below) require some leverage. It's recommended that scalpers start with a large amount of capital. Opening and closing larger positions allow you to reduce the marginal costs of trading and maximize potential gains.
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.

Swing trading is one of the most popular forms of active trading, where traders look for intermediate-term opportunities using various forms of technical analysis. If you're interested in swing trading, you should be intimately familiar with technical analysis.

It needs sheer dedication, hard work, patience, quick wit and immense knowledge to be successful in intraday trading. Successful intraday trading involves 90% waiting and 10% execution. So, yes, it can make a trader rich in a relatively short period of time if the correct processes are followed, and yes, it is possible to hold on to the profits in the long-term if the correct strategies are followed.
Assess how much capital you're willing to risk on each trade. Many successful day traders risk less than 1% to 2% of their account per trade. If you have a $40,000 trading account and are willing to risk 0.5% of your capital on each trade, your maximum loss per trade is $200 (0.005 x $40,000). Set aside a surplus amount of funds you can trade with and you're prepared to lose. Remember, it may or may not happen.
