Day trading requires more money than just a deposit, though. Get setup with a good computer, one or two monitors, a trading platform and data feeds. With many brokers the data feeds for various markets cost money, so pick a market and stick with it. There is no reason to pay for data feeds you won't be using. Also, a consistent income isn't likely during the first six months to a year, so save up for living expenses if attempting to day trade as a primary income stream.
Individual traders often manage other people's money or simply trade with their own. Few of them have access to a trading desk, but they often have strong ties to a brokerage (due to the large amounts they spend on commissions) and access to other resources. However, the limited scope of these resources prevents them from competing directly with institutional day traders. Instead, they are forced to take more risks. Individual traders typically day trade using technical analysis and swing trades—combined with some leverage—to generate adequate profits on such small price movements in highly liquid stocks.

Once you have a specific set of entry rules, scan through more charts to see if those conditions are generated each day (assuming you want to day trade every day) and more often than not produce a price move in the anticipated direction. If so, you have a potential entry point for a strategy. You'll then need to assess how to exit, or sell, those trades.

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.
In March 2000, this bubble burst, and a large number of less-experienced day traders began to lose money as fast, or faster, than they had made during the buying frenzy. The NASDAQ crashed from 5000 back to 1200; many of the less-experienced traders went broke, although obviously it was possible to have made a fortune during that time by short selling or playing on volatility.[9][10]

There are a variety of methodologies to capitalize on market swings. Some traders prefer to trade after the market has confirmed a change of direction and trade with the developing momentum. Others may choose to enter the market on the long side after the market has dropped to the lower band of its price channel—in other words, buying short-term weakness and selling short-term strength. Both approaches can be profitable if implemented with skill and discipline over time.

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.
Scalping is a trading strategy geared towards profiting from minor price changes in a stock's price. Traders who implement this strategy place anywhere from 10 to a few hundred trades in a single day with the belief that small moves in stock price are easier to catch than large ones; traders who implement this strategy are known as scalpers. Many small profits can easily compound into large gains, if a strict exit strategy is used to prevent large losses.
The tick volume is measured by how much the price is has ticked “up” or “down” in that particular candle bar. So the more people are getting in at the time, the longer the volume line will become. This is because there will be more movement in price action with all of those entry orders flying in. So it makes sense that the volume indicator is, first of all, very accurate, and second has no real lag to it. It is currently showing you what the price action is doing the number of “ticks” on that candle bar. This results in the bar looking like this:
The two most common day trading chart patterns are reversals and continuations. Whilst the former indicates a trend will reverse once completed, the latter suggests the trend will continue to rise. Understanding these trading patterns, as well as ‘triangles’, ‘head and shoulders’, ‘cup and handle’, ‘wedges’ and plenty more, will all make you better informed when it comes to employing your trading strategies.

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.
Scalping utilizes larger position sizes for smaller price gains in the smallest period of holding time. It is performed intraday. The main goal is to buy or sell a number of shares at the bid — or ask — price and then quickly sell them a few cents higher or lower for a profit. The holding times can vary from seconds to minutes, and in some cases up to several hours. The position is closed before the end of the total market trading session, which can extend to 8 p.m. EST.
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.
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]

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.

If the strategy is within your risk limit, then testing begins. Manually go through historical charts to find your entries, noting whether your stop loss or target would have been hit. Paper trade in this way for at least 50 to 100 trades, noting whether the strategy was profitable and if it meets your expectations. If it does, proceed to trading the strategy in a demo account in real time. If it's profitable over the course of two months or more in a simulated environment, proceed with day trading the strategy with real capital. If the strategy isn't profitable, start over.
