Suppose a trader employs scalping to profit off price movements for a stock ABC trading for $10. The trader will buy and sell a massive tranche of ABC shares, say 50,000, and sell them during opportune price movements of small amounts. For example, they might choose to buy and sell in price increments of $0.05, making small profits that add up at the end of the day because they are making the purchase and sale in bulk.

Day trading is making short-term trades, lasting less than one day, in an attempt to extract a profit from the financial markets. Some day traders are very active, making many trades each day, while other traders may only make one or two trades per day. The most common day trading markets are stocks, forex and futures. Day trading can be a part-time or full-time career, depending on the trader's style.
But this description of swing trading is a simplification. In reality, swing trading sits in the middle of the continuum between day trading to trend trading. A day trader will hold a stock anywhere from a few seconds to a few hours but never more than a day; a trend trader examines the long-term fundamental trends of a stock or index and may hold the stock for a few weeks or months. Swing traders hold a particular stock for a period of time, generally a few days to two or three weeks, which is between those extremes, and they will trade the stock on the basis of its intra-week or intra-month oscillations between optimism and pessimism.
In parallel to stock trading, starting at the end of the 1990s, several new market maker firms provided foreign exchange and derivative day trading through electronic trading platforms. These allowed day traders to have instant access to decentralised markets such as forex and global markets through derivatives such as contracts for difference. Most of these firms were based in the UK and later in less restrictive jurisdictions, this was in part due to the regulations in the US prohibiting this type of over-the-counter trading. These firms typically provide trading on margin allowing day traders to take large position with relatively small capital, but with the associated increase in risk. The retail foreign exchange trading became popular to day trade due to its liquidity and the 24-hour nature of the market.
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.” 
Following the 1987 stock market crash, the SEC adopted "Order Handling Rules" which required market makers to publish their best bid and ask on the NASDAQ. Another reform made was the "Small-order execution system", or "SOES", which required market makers to buy or sell, immediately, small orders (up to 1000 shares) at the market maker's listed bid or ask. The design of the system gave rise to arbitrage by a small group of traders known as the "SOES bandits", who made sizable profits buying and selling small orders to market makers by anticipating price moves before they were reflected in the published inside bid/ask prices. The SOES system ultimately led to trading facilitated by software instead of market makers via ECNs.
Due to the increased leverage and quick returns, day trading can be extremely profitable. The downside is that if done incorrectly, it can also be extremely unprofitable.

Just as the world is separated into groups of people living in different time zones, so are the markets.
