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!
Retail day traders are competing with professionals. Pros know the tricks and traps. They have expensive trading technology, data subscriptions and personal connections. They’re perfectly outfitted to succeed, and even then they often fail. Among these pros are high-frequency traders, who are looking to skim pennies or fractions of pennies — the day trader’s profit — off every trade. It’s a crowded field, and the pros love to have inexperienced investors join the fray. That helps them profit.

The bid–ask spread is two sides of the same coin. The spread can be viewed as trading bonuses or costs according to different parties and different strategies. On one hand, traders who do NOT wish to queue their order, instead paying the market price, pay the spreads (costs). On the other hand, traders who wish to queue and wait for execution receive the spreads (bonuses). Some day trading strategies attempt to capture the spread as additional, or even the only, profits for successful trades.[18]

Make a plan to trade this strategy in a Simulated Trading account for 1 month to test your skills. Your objects will be to achieve a percentage of success (or accuracy) of at least 60%. You also must maintain a profit loss ratio of at least 1:1 (winners are equal size on average as losers). If you can achieve these statistics, then you are positioned well to trade live. During the 1 month of practice, try to take 6 trades per day.
Risk management - Rather than looking for one big trade, the way a trend trader might, the scalper looks for hundreds of small profits throughout the day. In this process the scalper might also take hundreds of small losses during the same time period. For this reason a scalper must have very strict risk management never allowing a loss to accumulate.
A scalper intends to take as many small profits as possible, without letting them evaporate. This is the opposite of the "let your profits run" mindset, which attempts to optimize positive trading results by increasing the size of winning trades while letting others reverse. Scalping achieves results by increasing the number of winners and sacrificing the size of the wins. It's not uncommon for a trader with a longer time frame to achieve positive results by winning only half or even less of his or her trades – it's just that the wins are much bigger than the losses. A successful scalper, however, will have a much higher ratio of winning trades versus losing ones, while keeping profits roughly equal or slightly bigger than losses.
Fundamental analysis usually involves using a company's financial statements, discounted cash flow modeling and other tools to assess a company's intrinsic value. Scalpers may trade on news or events that drastically affect a company’s value immediately after its release. In some cases, they may also use short term changes in fundamental ratios to scalp trades but typically they focus mostly on the technical charts.
The first key to successful swing trading is picking the right stocks. The best candidates are large-cap stocks, which are among the most actively traded stocks on the major exchanges. In an active market, these stocks will swing between broadly defined high and low extremes, and the swing trader will ride the wave in one direction for a couple of days or weeks only to switch to the opposite side of the trade when the stock reverses direction.
Day traders are attuned to events that cause short-term market moves. Trading the news is a popular technique. Scheduled announcements such as economic statistics, corporate earnings or interest rates are subject to market expectations and market psychology. Markets react when those expectations are not met or are exceeded, usually with sudden, significant moves, which can benefit day traders.
Futures are a contract that match up a buyer and seller at a specific price, with the buyer agreeing to pay that price for the asset when the contract expires in the future. The seller is agreeing to deliver the asset, like oil for example, to the buyer when the contract expires. Day traders are never required to deliver or pay for the actual asset, because all positions are opened and closed within the day (no open obligations). Profits are losses are based on the prices the contract is opened and closed at.

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.

Sincere interviewed professional day trader John Kurisko, Sincere states, Kurisko believes that some of the reversals can be blamed on traders using high-speed computers with black-box algorithms scalping for pennies. “That’s one of the reasons many traders get frustrated with the market. The timing is not like it used to be, and many of the old rules don’t work like before.” [2]
Scalpers need to be disciplined and need to stick to their trading regimen very closely. Any decision that needs to be made should be done so with certainty. But scalpers should also be very flexible, because market conditions are very fluid and if a trade isn't going as expected, they'll need to fix the situation as quickly as possible without incurring too much of a loss. 

Swing, or range, trading Traders find a stock that tends to bounce around between a low and a high price, called a "range bound" stock, and they buy when it nears the low and sell when it nears the high. They may also sell short when the stock reaches the high point, trying to profit as the stock falls to the low and then close out the short position.
