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.
A scalp trader can look to make money in a variety of ways. One method is to have a set profit target amount per trade. This profit target should be relative to the price of the security and can range between .%1 - .25%. Another method is to track stocks breaking out to new intra-day highs or lows and utilizing Level II to capture as much profit as possible. This method requires an enormous amount of concentration and flawless order execution. Lastly, some scalp traders will follow the news and trade upcoming or current events that can cause increased volatility in a stock.

The ability for individuals to day trade coincided with the extreme bull market in technological issues from 1997 to early 2000, known as the dot-com bubble. From 1997 to 2000, the NASDAQ rose from 1200 to 5000. Many naive investors with little market experience made huge profits buying these stocks in the morning and selling them in the afternoon, at 400% margin rates.

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.
Commissions for direct-access brokers are calculated based on volume. The more shares traded, the cheaper the commission. The average commission per trade is roughly $5 per round trip (getting in and out of a position). While a retail broker might charge $7 or more per trade regardless of the trade size, a typical direct-access broker may charge anywhere from $0.01 to $0.0002 per share traded (from $10 down to $.20 per 1000 shares), or $0.25 per futures contract. A scalper can cover such costs with even a minimal gain.
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 use technical analysis but within this style, can be either discretionary or system traders. Discretionary scalpers will make each trading decision in real time (albeit very quickly), whereas system scalpers follow a scalping system without making any individual trading decisions. Scalpers primarily use the market's prices to make their trading decisions, but some scalpers also use one or more technical indicators, such as moving averages, channel bands, and other chart patterns.
Mutual funds are off-limits for intraday trading. The design of these funds is for the long-term investor, and they can only be bought and sold through a broker or the fund's investment company. Also, a mutual fund's price posts only once, at the close of the trading day. This price is known as the net asset value (NAV) and reflects all of the intraday movement of the fund's assets, less its liabilities, calculated on a per-share basis.
This trading strategy used to be defined as spread trading where you would take profits where small gaps expanded and contracted between the bid and the ask price for a stock. This strategy has now evolved to include technical indicators, support/resistance levels, and volume spikes to make round-trip trades lasting seconds to a few minutes. The basic idea of scalping is to take advantage of market inefficiencies using speed and high trading volume to create quick profits. Click here for more information on scalping.
An unexpected movement can wipe all your investment in a few minutes. Hence, it is important to keep in mind a few intraday trading basics while carrying out intraday trading. Do not trade in the first hour as the opening range is established during that time. The fluctuations of this range can help to identify the intraday trend. Move with the market trend as it allows potential for a greater profit if the trend continues. Another basic rule is to fix entry price and target levels. Set a stop-loss limit so that your losses will be curtailed if the share drops. Also, withdraw if your desired profits are met. Stick to your plan and carry trade in a disciplined manner.

The price movements of any stock are posted throughout the trading day and summarized at the end of the trading day. For example, April 2, 2019, shares of Apple Inc.

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.
Solid article breaking down the two main strategies for swing trading. I stumbled on swing trading about 5-6 years ago and didn't even actually know what it was called at the time! For the last 5 years, I've been primarily trading postive reversals using the Swing Low method you describe here. After all, we've been in this amazing bull market for the last 8 years, so why fight the overall trend? One key point I would say is it is important to find a method that fit's your personality. I used attempt swing trades based upon breakouts. I found that I feared missing out on a large move, so I would pile into a trade with little thought about the risk vs. reward. I would chase prices higher. I also chased different trading methods, jumping from one to another. Long story didn't work. :-) I described after much trial & error, I finally settled on a trading method that fit my personality. I have found that as a trader, you answer to yourself. Find a trading met
The reason is because all too often the price can drop and you will end up giving up that profit. Instead, as soon as I’ve reached my first profit target (if I’m risking $100, then as soon as I’m up $100), I’ll sell 1/2 my position and set my stop at breakeven. This method of scaling out ensures small profits on all trades that move in your favor, giving you a better percentage of success.
The goal of swing trading is to capture a chunk of a potential price move. While some traders seek out volatile stocks with lots of movement, others may prefer more sedate stocks. In either case, swing trading is the process of identifying where an asset's price is likely to move next, entering a position, and then capturing a chunk of the profit from that move.
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. 

Day traders use only risk capital which they can afford to lose. Not only does this protect them from financial ruin, but it also helps eliminate emotion from their trading. A large amount of capital is often necessary to capitalize effectively on intraday price movements. Having access to a margin account is also key, since volatile swings can incur margin calls on short notice.
