This part is all up to you. There is no "line crossing," "arrow appearing" or "a small voice telling you to buy now!" You have to understand a little bit about how the price action works before you decide on your entry. Using our example, the Volume indicator shot up drastically meaning that traders are getting in on the action and thus driving the price upwards!
Trading stocks intraday offers different opportunities than a traditional ‘buy and hold’ strategy. Speculating on stock prices via CFDs or spread betting for example, mean traders can profit from falling prices too. Margin or leverage also reduce the capital required to open a position. So you can take a position on the latest news release, product announcement or financial report – as well as technical indicators.
A pure scalper will make a number of trades each day — perhaps in the hundreds. A scalper will mostly utilize one-minute charts since the time frame is small, and he or she needs to see the setups as they shape up in as close to real time as possible. Supporting systems such as Direct Access Trading (DAT) and Level 2 quotations are essential for this type of trading. Automatic instant execution of orders is crucial to a scalper, so a direct-access broker is the preferred weapon of choice.
A day trader often closes all trades before the end of the trading day, so not to hold open positions overnight. A day traders' effectiveness may be limited by the bid-ask spread, trading commissions, as well as expenses for real-time news feeds and analytics software. Successful day trading requires extensive knowledge and experience. Day traders employ a variety of methods to make trading decisions. Some traders employ computer trading models that use technical analysis to calculate favorable probabilities, while some trade on their instinct.
Many orders placed by investors and traders begin to execute as soon as the markets open in the morning, which contributes to price volatility. A seasoned player may be able to recognize patterns and pick appropriately to make profits. But for newbies, it may be better just to read the market without making any moves for the first 15 to 20 minutes. The middle hours are usually less volatile, and then movement begins to pick up again toward the closing bell. Though the rush hours offer opportunities, it’s safer for beginners to avoid them at first.
