Scalping highly liquid instruments for off-the-floor day traders involves taking quick profits while minimizing risk (loss exposure).[14] It applies technical analysis concepts such as over/under-bought, support and resistance zones as well as trendline, trading channel to enter the market at key points and take quick profits from small moves. The basic idea of scalping is to exploit the inefficiency of the market when volatility increases and the trading range expands. Scalpers also use the "fade" technique. When stock values suddenly rise, they short sell securities that seem overvalued.[15]
ECNs and exchanges are usually known to traders by a three- or four-letter designators, which identify the ECN or exchange on Level II stock screens. The first of these was Instinet (or "inet"), which was founded in 1969 as a way for major institutions to bypass the increasingly cumbersome and expensive NYSE, and to allow them to trade during hours when the exchanges were closed.[6] Early ECNs such as Instinet were very unfriendly to small investors, because they tended to give large institutions better prices than were available to the public. This resulted in a fragmented and sometimes illiquid market.
Some of the common mistakes that scalpers make are poor execution, poor strategy, not taking stop-losses, over-leveraging, late entries, late exits and overtrading. Scalping generates heavy commissions due to the high number of transactions. A per-share commission pricing structure is beneficial to scalpers, especially for those who tend to scale smaller pieces in and out of positions.
Scalping in this sense is the practice of purchasing a security for one's own account shortly before recommending that security for long-term investment and then immediately selling the security at a profit upon the rise in the market price following the recommendation.[5] The Supreme Court of the United States has ruled that scalping by an investment adviser operates as a fraud or deceit upon any client or prospective client and is a violation of the Investment Advisers Act of 1940.[6] The prohibition on scalping has been applied against persons who are not registered investment advisers, and it has been ruled that scalping is also a violation of Rule 10b-5 under the Securities Exchange Act of 1934 if the scalper has a relationship of trust and confidence with the persons to whom the recommendation is made.[7] The Securities and Exchange Commission has stated that it is committed to stamping out scalping schemes.[8]
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.

There are two primary divisions of professional day traders: those who work alone and/or those who work for a larger institution. Most day traders who trade for a living work for a large institution. These traders have an advantage because they have access to a direct line, a trading desk, large amounts of capital and leverage, expensive analytical software, and much more. These traders are typically looking for easy profits that can be made from arbitrage opportunities and news events, and these resources allow them to capitalize on these less risky day trades before individual traders can react.

Scalping proves to be an extremely effective strategy – even for those who use it purely as a supplementary strategy. The same goes for Forex 1-minute scalping. However, it is important to understand that scalping is hard work. Scalpers are rewarded for quantitative work – the more Forex scalping they perform, the larger the profits they achieve. In the end, the strategy has to match not only your personality, but also your trading style and abilities.

The most significant benefit of day trading is that positions are not affected by the possibility of negative overnight news that has the potential to impact the price of securities materially. Such news includes vital economic and earnings reports, as well as broker upgrades and downgrades that occur either before the market opens or after the market closes.

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.
Scalpers buy low and sell high, buy high and sell higher, or short high and cover low, or short low and cover lower. They tend to utilize Level 2 and time of sales windows to route orders to the most liquid market makers and ECNs for quick executions. The point-and-click style execution through the Level 2 window or pre-programmed hotkeys are the quickest methods for the speediest order fills. Scalping is purely based on technical analysis and short-term price fluctuations. Due to the extensive use of leverage, scalping is considered a high-risk style of trading.

Different markets require different amounts of capital to day trade. Stocks are popular, but also the most capital intensive. If you want to day trade stocks in the US, the absolute minimum you need is $25,000. And you'll actually need more because you need to keep your balance above $25,000. Starting with $30,000 or more is recommended. The stock market provides up to 4:1 leverage on day trades.

Spreads are bonuses as well as costs - Stock Markets operate on a bid and ask based system. The numerical difference between the bid and ask prices is referred to as the spread between them. The ask prices are immediate execution (market) prices for quick buyers (ask takers); bid prices for quick sellers (bid takers). If a trade is executed at market prices, closing that trade immediately without queuing would not get you back the amount paid because of the bid/ask difference. 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.
Identify a stock or ETF where the weekly trend is up and the bottoms on the daily bar chart tend to be short and sharp. Analyze how the stock or ETF has behaved since the beginning of the trend. If it has returned to the moving average 3 times and penetrated it by an average of 1.5% of its price, place a buy order approximately 1% of the instrument's price below the moving average, a little more shallow than the previous declines.
The profit potential of day trading is perhaps one of the most debated and misunderstood topics on Wall Street. Internet day trading scams have lured amateurs by promising enormous returns in a short period. The idea that this kind of trading is a get-rich-quick scheme persists. Some people day trade without sufficient knowledge. But there are day traders who make a successful living despite—or perhaps because of—the risks.
